ATS stat - what is normal?

Important to know is that you have an information advantage:
- you see that they attempt to steal 80 or 90%,but you also see their positional fold to 3bet stats and act accordingly!
- you plan to punish them by 3betting, but THEY only see your average 3bet values

So, in their eyes they see you 3betting a bit more than usual, but nothing drastic.

I would however not call more SC. You still play out of position and when you hit big you may not get a payout - because villains range is so weak. Plus you induce a squeeze from BB, if you do that from SB.

On rush-and-cash tables it may be OK to re-raise them from the BB with a wider range, but still be cautious from the SB for the reasons SvenBe suggests.

On a standard table I don not want such a player on my immediate right — I would just leave.

You can use Equilab to determine what ranges are good to 3Bet vs an 80% open.

All the best,
VS

general rule of thumb is to 3bet a third of the opponent's opening range. If he's opening 90% you can get away with 30% 3bet range for sure. And make sure to use polarized range with lots of trash if he's folding >70%+ vs a 3bet.

If he's folding 75-80%+ without adjusting you could even start to skew your value:bluff ratio -> Why 3bet a hand like 99 or AJ/KQ if he's folding almost always? As for bluffs, don't waste your 65s or A5s - instead use your 64o or 32s

A hyper-exploitative range would be something like (paste in equilab):
TT+, AQs+, 74s-72s, 64s-62s, 53s-52s, 42s+, 32s, AQo+, T3o-T2o, 95o-92o, 85o-82o, 75o-72o, 62o+, 52o+, 42o+, 32o

As he starts to adjust and fold less (60-70% fold vs 3bet), re-add 99 88 AJ KQ ATs KJs to your value 3bet range and remove some of the worse bluffs (assuming he's still opening 80% -> then you should never be folding any hand in the BB cos you have position + pot odds so your VPIP should be higher than his)

88+, ATs+, KJs+, 64s-62s, 53s-52s, 42s+, 32s, AJo+, KQo, 95o-92o, 85o-82o, 74o-72o, 64o-62o, 52o+, 42o+, 32o

If he's going crazy with the 4bets [10-15% 4b frequency when facing a 3bet] (while still opening 70-80% range), it means he would still be 4betting with a 7-12% 4bet range which is insanely high.

Which would mean you can start ripping it in with 88+, maybe 22-77, AJ, KQs, ATs

Theoretically you need a 5:5 or 6:4 value to bluff ratio for your 3bet range (value = not folding to 4bet) if you want to be unexploitable vs a 4bet bluff. But it's going to be really hard for your opponent to do anything when you're going ape on him preflop and maybe even postflop you can start raising all sorts of random backdoor equity hands.

This should force him to tighten up to 50-60% unless he's stupid.

Thanks for the tip. I did not know that.

I will make their ATS into ATM.

On sites without HUDs, its pretty amazing how little players adjust to stealing 100% on the button and SB. I am talking about 10 euro cash game.

I would expect this is on <NL10 also the case and maybe on some higher limits as well.

Great post by mbml, learned a lot!
