BB is a bad MSS player, 13 / 12 / 6.1% 3bet with low post flop skills. AF 7.8 (!), 47% (he feels pot committed a lot ). Loses 3bb/100 over 5k hands (!) while playing MSS, that is how bad he is.

Notes:
- Horrible post flop.
- 3bet AI with ATCs (I kind of targeted him, sue me )
- Open shoves AJo with a small stack (no auto rebuy).
- Raises and 4bets AI from BTN with AJs.
- Calls with ATo and fires 3 barrels with mid pair
- SB vs BB raise and 4bets ATo.

MP1 is 20 / 2 / 0% 3bet (!) over 1.4k hands with impressive loss rate of -15 bb/100. AF 1.3, 20%.

Notes:
- Always tries reverse float.
- Never folds a PP.

So, a lovely situation that I described in "fish schooling" topic

I decided for a larger cbet even against 2 players since these guys don't fold anything, anytime, for anybody.

Unfortunately, Ace falls on the turn and these guys have it a lot of the time, especially BB.
I think he wouldn't 3bet me with crappy Ace since I stacked him a few times when trying such moves but he is definitely calling it preflop.

On the river another Ace makes it slightly less likely one of them has it but I decide to fold.

1. I need line check with correct thought process in this situation. These come up a lot.

Total pot: $4.64 | Rake: $0.23

Results below:

Like... I don't know, we're getting 3:1 to call the jam. If he thinks this is a good bluffing spot (it's terrible but I've seen that happen) or whatever we MIGHT be good calling. Super marginal though -- it's probably better to fold and make a note on EXACTLY what he did that with for future reference, if the station called (which he almost certainly would).

EDIT: LOL @ this guy. Kay, so he is capable of bluffing that spot. Next time call down OPs TPs (if the board pair isn't tops like here) and good second pairs in this spot; you're good really often and you have killer odds.

EDIT2: Actually we pretty much HAVE to call down here even if we're not sure what he does this with because the station will definitely call with worse -- so in reality we're getting 4:1; odds too good to pass up. The uncertainty alone makes it correct to call down this spot with those odds.

Worst case scenario is that I call, then MP1 jams, then I feel like shit. If I am the last to act, then it is different but these passive guys are born to shove rivers if they think they are good. Not to mention that AJ is right for his range.
