CO is winning regular 28/16
BB is 79/53 fish, bad aggressive

Reads I have on him are, that he mashes pot button quite alot, he did it with stuff ranging from air to 2nd pair type hands, to top pair good kicker. Few hands ago I 3bet him for value he calls, flop comes Q22 I check behind /w AK, expecting to snap off a PSB by him, he pots it, turn comes K, he's got 22bb left and shoves I call he turns KQo.

He also once did a massive 3bet PF with 44 being 35bb deep and called a shove, thats probably not that important for this hand, but shows something about his 3betting.

"BB is 79/53 fish, bad aggressive"　- is this over big sample?

That's not quite a fish but a maniac.

I'd bet 1/3 pot on turn to induce, snap off a shove.

I got 81 hands on him but ptr has him like that for 12k hands big loser (-37 BB/100)

in preflop, dont play guessing games with 88 post when you have a clearly +EV spot just jamming it in this fishes face - expect to get called by worse often

I'd make it 25 pre, as played bet a third of remaining stacks.

+1 on inducer bet and I call PF as well. If he's truely bluffing pot a lot I may not 4bet at all depending on what I think about his get-it-in-Pf range.

The PF read from when he was 35bb deep seems more like the standard "I'm tilted and have a pair...flipping against AK to get even so I bet big" and I wouldn't want to draw conclusions about his full stakced/non-tilted play from it.

If he indeed gets it in PF with worse pairs obviously 4bet PF and probably flat big cards to flop a pair and collect at least one PSB (nice implied pair odds omnomnom).

I'm leaning towards a 4b preflop not only because we're ahead of his stack off range, but it's going to be difficult for us to play postflop when we flop 2nd pair or worse majority of the time.

4bet/call.. You have a read he goes crazy with lower PPs so go for it. 88 flops ****.

As played bet $20, milk him in chat and tank call

never seen a 28/16 winning player
