First session went a bit longer than planned, about 2,5K hands. Project started with a heater:

There are some thought that have risen up while playing PLO2, but I will keep them in my head for now. Don't want to make too quick conclusions yet.
Here are some hands I marked from the session:
#1

Hero (BTN): 803 BB
SB: 116 BB (VPIP: 32.00, PFR: 20.00, 3Bet Preflop: 9.09, Hands: 28)
BB: 97 BB (VPIP: 40.00, PFR: 10.00, 3Bet Preflop: 13.33, Hands: 30)
UTG: 101.5 BB (VPIP: 30.00, PFR: 13.16, 3Bet Preflop: 3.66, Hands: 193)
MP: 100 BB (VPIP: 16.77, PFR: 11.64, 3Bet Preflop: 2.09, Hands: 517)
CO: 209 BB (VPIP: 58.49, PFR: 22.64, 3Bet Preflop: 9.52, Hands: 53)
SB posts SB 0.5 BB, BB posts BB 1 BB
Pre Flop: (pot: 1.5 BB) Hero has 3♣ A♦ 8♦ A♣
fold, MP raises to 3 BB, CO calls 3 BB, Hero raises to 13.5 BB, SB calls 13 BB, fold, fold, CO calls 10.5 BB
Flop: (44.5 BB, 3 players) Q♥ Q♣ Q♠
SB checks, CO bets 43 BB, Hero calls 43 BB, fold
Kind of flop that is not that great. Hand is pretty much locked and it's really hard to get value from anyone. And then CO donks for a pot in 3bet pot, which didn't make ANY sense. I almost folded, but as I looked at his stats I thought that as he understands something about poker he is not a passive drawer. Plan was to call flop bet and if he shoves turn I would fold.
Turn: (130.5 BB, 2 players) A♥
CO checks, Hero checks
When I saw turn I thought "for fuck's sake!" as it doesn't really change anything but mentally makes it harder to fold. And opponent might think that A on the board blocks my AA hands which is the most obvious hand in my range. Although when I call flop I have Q on my range too, so it's not a good spot for opponent to barrel. He checked, which didn't help me a lot as the river would have the exact same spot unless it's A or Q.
River: (130.5 BB, 2 players) K♠
CO bets 126 BB, Hero calls 126 BB
When the river came, I said to myself "FOR FUCK'S SAKE!" as now the ONLY worse hand opponent might bet for value on the flop sucked out on me. And then opponent bets pot.
First I was quite ready to fold. Then I thought why would he bet pot with KK, and maximize the folding equity vs. Aces. Or is he even capable of thinking like that. Or would he be ballsy enough to pot with air and assume I would fold? And then I thought that either flop or river bet doesn't make that much sense with Q, and if I had Q myself I would bet something on the turn. So I am at the top of my range. To fold that, I would need pretty hard evidence that opponent isn't bluffing there. And all evidence leads to the fact that there's something fishy going on. So I call.
CO shows 2♥ 6♠ 3♥ 3♦ (Full House, Queens full of Threes)
(Pre 28%, Flop 0%, Turn 0%)
Hero shows 3♣ A♦ 8♦ A♣ (Full House, Aces full of Queens)
(Pre 72%, Flop 100%, Turn 100%)
Hero wins 370 BB

SB posts SB 0.5 BB, BB posts BB 1 BB
Pre Flop: (pot: 1.5 BB) Hero has 5♦ A♣ 8♣ T♥
fold, fold, fold, Hero raises to 3.5 BB, SB calls 3 BB, fold
Flop: (8 BB, 2 players) 9♠ 6♠ 8♦
SB checks, Hero checks
Here I checked, not enough folding equity on that board. On some turns we can valuebet, some we can check and some we can bluff.
Turn: (8 BB, 2 players) 4♣
SB bets 4 BB, Hero calls 4 BB
57 gets there, but we have one 5 ourselves. Sizing is the interesting here. Often half a pot on this kind of board is sort of "I am not sure what to do so I bet half a pot". If he had T7 or 75 (we block both) he would often bet bigger. So I called with plan to bluff a lot of rivers if his sizing looks weak and I don't improve.
River: (16 BB, 2 players) 2♥
SB bets 8 BB, Hero raises to 26 BB, fold
River is a blank, and he bets half a pot again. Now the funny part is that as I raise, I pretty much rep nothing. If I had T7, I would have bet the flop or raised the turn. If I don't raise turn with 75 why would I do it on the river? So against a good thinking player this raise would be suicidal. Here the opponent is a bit loose and passive, and his betsizing tells me that he isn't on very high level of poker strategy and thinking. So when he faces a raise, he probably just thinks "I can't call with this hand" without ever thinking about my hand. Because he doesn't really understand range thinking.
Hero wins 31 BB

Pre Flop: (pot: 1.5 BB) Hero has 6♠ 8♦ 5♣ 9♣
Hero raises to 2 BB, MP calls 2 BB, CO calls 2 BB, fold, SB calls 1.5 BB, BB calls 1 BB
Flop: (10 BB, 5 players) 3♣ 4♣ 7♠
SB checks, BB checks, Hero bets 1 BB, fold, CO calls 1 BB, SB calls 1 BB, BB calls 1 BB
This is just a funny one. I misclick on the flop with nuts and redraws. Opponent calls with gutshot and backdoors.
Turn: (14 BB, 4 players) 5♠
SB checks, BB checks, Hero bets 13.5 BB, CO raises to 54 BB, fold, fold, Hero raises to 175.5 BB, CO calls 83.5 BB and is all-in
Turn is THE ACTION card. I still have the nuts with redraws. Now he has the nuts with redraws. We both have the flushdraw and gutshot to higher straight. And I have few full house outs. Big flip.
River: (289 BB, 2 players) 8♥
And I win.
Hero shows 6♠ 8♦ 5♣ 9♣ (Straight, Nine High)
