thank you for your kind words
Online ranking systems (OPR, SharkScope, ProLabs/Top Shark).
This topic is not covered at all in general poker literature. For some bizarre reasons it's not even covered in MTT VODs in English community. I am not sure is it some sort of local policies about third-party systems, but Russian community VODs or any trainings use them all the time.
Anyway, it may come as a surprise, but online ranking systems (I also refer them as “host systems”) are mandatory for modern MTT regular player, their importance is the same as HUD, that is why lack of information about them is shocking.
These systems and info from them is a primary source for initial opponent evaluation, most of fishes and strong regulars can be detected immediately based on them. Again, it's just one of the sources, you shouldn't solely depend on it, it gives the first impression which can be very misleading, so you shouldn't stick too much to it. The main approach is to check an unknown opponent and see if you can roughly categorize him based on online ranking system data. Later your conclusion will be corrected by HUD stats and own notes and observations you get during live play.
Many tournaments under various rooms may be not tracked at all by some online ranking systems.
Some history and rules.
Spoiler
Online ranking systems are relatively new, that is why last couple of years there were conflicts between poker rooms and these providers. In particular, Fulltilt banned commercial SharkScope, Top Shark explicitly and free OPR was officially not recommended during live play. PokerStars used to forbid SharkScope, Top Shark during live play but allowed OPR without restrictions. Recently PokerStars had forced all online ranking systems to hide by default ROI and Profit stats for their players, and they can be shown only if player explicitly allowed that. All systems added that restriction for PokerStars players and they officially lifted ban from commercial systems. So, right now all mentioned online ranking systems for tournaments are allowed without any restrictions by all major poker rooms and networks. At least I investigated poker room rules, policies, terms and conditions for all rooms I mentioned in the previous articles. You can find my discovery results here: https://sourceforge.net/p/usunpokertools/wiki/Licenses%20and%20Restrictions/
It won't hurt to double check your poker room policies before using them. 3rd party tools using online ranking systems for integration are usually also allowed by poker rooms during play.
Once again, ROI and Profit numbers for PokerStars players are currently hidden by default on all systems!
Automation.
Normally regular player start actively using these systems in later stages, when there are less tables left and they are focusing on tables and opponents left. It's because by default they manually check players one by one, they just don't have time to do it earlier and prefer ABC play on earlier stages.
However, there are tools to automate the process and lift this restriction:
Spoiler
1) Commercial systems SharkScope and ProLabs provide their own desktop applications/HUDs with main data to all their subscribers. In most cases they are allowed by major poker rooms, but check room policies just in case.
The drawback is that subscription cost money and may be you won't be happy to have multiple HUDs from multiple providers on the same table (like local tracker HUD PT, HM + online ranking system HUD). The positive is thing is that it will be very well supported and won't break when host systems change their Integration API sometimes.
2) Free OPR doesn't have its own desktop applications and HUD, and it's clear why, they live from banners and ads, and don't have much money to support anything else except their main site.
There are some 3rd party automation tools/HUDs integrated with OPR, but you should always remember that they are not officially allowed by OPR and their usage can easily cause ban by IP from OPR.
Anyway, here is a commercial HUD for OPR:
OpenTool http://fishinterceptor.com/en
Its support topic is in Russian-language community: https://forums.pokerstrategy.com/ru/forum/thread.php?threadid=513994
It was very popular before PokerStars forced OPR to close ROI/Profit and even ABI stats. There is a minor risk to get banned by OPR, because it searches for player only on demand, by user clicks, and therefore it shouldn't generate high load on OPR.
It is officially allowed by PokerStars.
3) Here comes my own project to support integration with online poker ranking systems and multiple rooms, it's free and open source:
usunpokertools - https://sourceforge.net/p/usunpokertools/wiki/Home/
Its support topic is in Russian-language community: https://forums.pokerstrategy.com/ru/forum/thread.php?threadid=603065
It'll be presented to English community after next major release 1.4, when I expect to polish it completely.
It is officially allowed by PokerStars. It is officially approved and licensed by SharkScope.
The main idea here is to provide integration with multiple rooms, and online ranking systems (OPR – officially it's just a demo but there is full functional support, SharkScope – officially approved, ProLabs/Top Shark – no response from them, but should be ok to use with them, PTR for cash only – no response from them, but should be ok to use with them). It doesn't have it's own HUD, it reuses other local tracker HUD(s) as simple containers, i.e. based on data retrieved from host system(s) tools generate one or many player notes and store them as local tracker HUD player notes (PT3,4, HM1, HM2 – for HM2 only limited support).
It provides both tools to search players manually one by one, and to enable auto-scan and auto search for everything from hand histories (it keeps elaborate local cache to avoid duplicate searches).
Auto scan for OPR can easily case ban by IP from them. Right now it generates quite high load with multi-threaded auto search. By default it is configured to auto-restrict 5-10 searches per 2 minutes but the danger of ban is still there - you can play around various settings. Sure, I support advanced support for list of proxies which is a workaround, but it's not so convenient and is kinda for advanced users.
Data from Online ranking systems/host systems.
1) OPR – officialpokerrankings.com
This the only major fully free online ranking system, and therefore the most popular. It only tracks PokerStars, PartyPoker, Ongame Network, Carbon from Merge Network, Fulltilt.
It doesn't have side applications, like own HUD or Integration API for 3rd party software. It is the only host system that explicitly forbids automated 3rd party search via it. If they think there are two many searches going from some IP, they just ban the whole IP, and user can only see redirect to “dip.officialpokerrankings.com” and after that can really use only proxy to access it.
OPR provides all standard info except graphs, it also shows a very important and underestimated info – breakdown by finishes by stages.
It's highly recommended to start with it and use manual search in the start to reduce risks of bans.
Let's go through some standard info provided by it: ROI, ITM, distance, ABI, AFS, R&A ratio, prizes, profit, fish by stages breakdown. For the rest host systems it's pretty much the same, differences will be covered explicitly.
Example page (it's a bit old):
Spoiler

- For some players stats are explicitly hidden, so you can mark this fact in notes, it may either mean that player is good reg with significant distance or some weak fish with huge losses, or may be just don't like to show his stats. In any case, at least this player knows what is online ranking system and therefore he is not a complete newbie.
- Distance is amount of tournaments played. It is important stat. 484 in example here. On smaller fields and rooms usually 300 is minimum to draw some conclusions, 500 is default ok distance, >1000 is more or less certain for average fields (AFS < 1000). If less than 100, it usually means no distance at all and all info can be ignored.
- Return of investment (ROI) in %. Is considered to be main financial stat, hidden for PokerStars by default. (-100%;-15%) is quite bad, it's a loosing player. From -8% up to +5% is around zero (“rakebot”). +45% is excellent and very strong, especially on higher limits. You should be careful with this stat – it can be heavily affected by swings on lower distance, fluke victory in huge tournament or lucky shot on much higher limits than his regular ones.
In this example +170% ROI is a clear sign that distance is not so big and player is in upswing. It's better to check may be it is a lucky shot in some huge or high-limit tournament. In this particular example, it appeared that player has 12 finishes in TOP3 in regular tournaments of the average buy-in, medium-size, but with abnormal high TOP-1 ratio. So, looks like regular but on major upswing. Low limits medium size won't likely give more than 100% ROI on significant distance, and on medium stakes it won't be higher than 50% normally. The higher limits – the lower ROI. The higher AFS – the more ROI can be, especially on swings.
- In the money (ITM) in %, additional somewhat important stat. Normal values for regulars are about 15-17%. It can be higher on smaller tournaments (check AFS) and lower down to 12% for larger tournaments, especially for loose aggressive regulars. If player has something like 20% on medium-size fields and not high ROI – it usually signals that here is too tight around bubbles, and he is a good target to abuse on pre-bubble/bubble stage. 10% and lower is a clear sign of weak player. If player has -15% and lower ROI and under 10% ITM on some distance it's almost sure a fish. If his finishes by stages are shifted to earlier stages – it's a guaranteed fish. Even if player has a good positive ROI, but ITM under 10% and bad finishes by stages – I'm sure that this is a lucky fish and just need to check what fluke big or high-limit MTT he's won (I don't even bother to check, just set “fish” label – it's just one more example how ROI stat is overestimated).
The conclusion here is that even with hidden ROI stat for PokerStars players we still go enough information to detect typical fish on open stats left.
In the example provided, 16% is normal for regular.
- Prizes in $ – not so important stat; just to see the volume. I don't consider player with less than 10k prizes as a regular, maximum semi-reg. 100k+ may mean something in combination with ROI and ABI stat, it can be a minimum requirement semi pro+.
Here we get 12k prizes, might be some reg.
- Profit in $ - additional stat of actual + or - results. Hidden for PokerStars by default. You don't really care much about it, ABI and ROI are more important.
+7.6k in example doesn't mean anything.
- Average buy-in in $, this is an important stat to see on what stakes player usually plays. It's even better to look all stats breakdown by limits/buy-ins. Beware that for rebuy tournaments actual total buy-in paid by any player is an estimated figure. They cannot track individual rebuys and add-ons, only average ones for each tournament. In “breakdown by limits” section, ABI displayed is not actual ABI paid, but just nominal buy-in, i.e. $3+0.3 rebuy&addon is displayed as $0-$4.99 limit in this breakdown. Seems total ABI is a normal one – consists of total estimated actual money put into the tournament.
9.24$ in example means low limits.
- Average field size (AFS) – to get an impression what tournaments player usually participate in. It really affects distance required to draw any conclusions. For AFS 500, it may be enough 300+ tournaments to tell something, for AFS 1000, it should be closer to 700 tournaments, for AFS 2000+, it starts from 1000+ tournaments and it's not a linear dependency, hardly anyone ever get legit distance for big tournaments.
523 in example – typical medium tournaments.
- Rebuy & addon ratio (RA) in %, it is useful to get the estimation of how many rebuys are in stats, it really affects how should we look on ABI. If you seen 90% RA in limits breakdown for $0-$4.99, it means that player doesn't really play micros, and actual buy-ins there are more likely to bee in 5-25% range.
There is one more important thing about rebuys in any online ranking system – they have no way to know how many rebuys and add-ons each player really made. They can only track the overall total of all rebuys and add-ons made in each tournament and record an average for every participant. Therefore, the higher RA, the less correct are ROI, Profit, ABI figures.
- Finishes by stage breakdown – it is very important and grossly underestimated stat. As already described above, it's not only the main stat in combination with ITM that can indicate fish with certainty, even regardless ROI, profit stats. It is also the only stat that can tell you a lot about player's style. High finishes in earlier stages (like 20/20) shows player sticks in very lightly near the tournament start – it means he is either very loose aggressive and not afraid to gamble or may be trying to build huge stack right away, or may be it's just a weak fish and calling station or maniac, who has no clue when it's time to fold.
30/30/20/15/5 – this is the main fish pattern with clear dis-balance leaning towards earlier finishes who rarely survives till later stages (5% late is very low, it usually shouldn't be less than 10% for plus players), if you see something like this – it's almost certain is a fish regardless all the rest stats.
15/20/30/20/15 – this is very dangerous loose aggressive player, late stage is very high and finishes are gradually distributed – he starts fight and table press from the first hand. If he lucky to build a big stack early, he won't wait for anything and will squeeze everything from this advantage.
11/20/40/19/10 – this is a real-life example of mid stakes+ very strong and very loose aggressive regular. This is really close to fish stats, but 14% ITM tells us not o jump into conclusions, and high ROI on big distance makes it clear who we face.
5/10/45/25/15 – typical stats for good reg who is tight in the start and getting more and more aggressive later in the tournament.
In example we got 2/10/53/21/13 – falls under the last category, compatible with typical regular and plays tight in the beginning and then loosen up. You should think twice before calling his all-in in early stage.
By the way, my usunpokertools would generate the following player note based on this data:
opr3Jun12: +170ROI/16ITM/484($9)/$12k(+7.6k)/523AFS/28RA 2/10/53/21/13
And here are initial conclusions we can make based on this:
- there is enough distance for initial conclusions, taking into consideration field sizes
- player is a winning regular of low limits;
- doesn't really wait for ITM and is able to move;
- standard style as tight in the start and more loose aggressive the further he goes in the tournament.
2) SharkScope - http://www.sharkscope.com/
Commercial system with only 5 free searches per day and 150 or 500 searches per day depending on the subscription type. Has its own desktop application with own HUD (I never used it).
It supports the widest set of tournaments, rooms and networks. It is very friendly to 3rd party systems/tools integrated with them, has official Integration API and promotes any tool that use it.
Data returned in comparison to OPR:
- Doesn't have finishes by stage breakdown info – this is the main disadvantage of this system.
- Default total ROI displayed is normalized by buy-ins. i.e. it is not total money ROI, but rather an average tournament results ROI, which is more important. ROI and profit are also hidden for PokerStars players by default.
- It has very useful graphs for player results, it really allows immediately resolve any uncertainty caused by standard stats contradictions and strange values. Regular MTT graph looks like a ladder steadily going up in the long run. Big swings usually indicate very loose aggressive style or tournament selection with huge variance (like hyper-turbo). Here we can easily see if +ROI/Profit is really caused by some single random big win with a clear downward tendency - then it's a clear fish. They are disabled for PokerStars players by default.
- It doesn't display Prizes $, and that is why ABI is not hidden here for PokerStars.
3) ProLabs/Top Shark - http://pokerprolabs.com/topshark/
Commercial system with only 10 free searches per day and 200 or higher searches per day depending on the subscription type. Has its own desktop application with own HUD (I never used it).
It supports the wide set of tournaments, rooms and networks (but less than SharkScope and started many rooms tracking later than SharkScope).
It doesn't have official Integration API yet, but seems doesn't care about 3rd party tools and doesn't try to block them.
Data returned in comparison to OPR:
- Has the same finishes by stage breakdown stats. They are disabled for PokerStars players by default.
- It has similar very useful graphs to SharkScope.
- It doesn't display Prizes $, and that is why ABI is not hidden here for PokerStars.
