MP2 is 20/2/3.7 over 280 hands or so. I have seen him slowplay a set on a 4-way flop and a HU turn, making a PSB on the river. I have also seen him lose his stack with a KK overpair met with heavy post flop aggression.

UTG is a 60VP$IP/low PFR donk.

I have been betting at most of the pots I've been involved in at this table.

One of the villains might very well have flopped a flush, so I check the turn in the middle. When MP2 makes his half pot bet I call, looking for a boat or a check-check river if he has the king and thinks I am full of shit on the flop. River brings me my boat so I make a half pot bet looking for a raise or a call. I'm hoping he's slowplaying the nut flush and is stupid enough to raise, but looking back he's probably not going to.

Thoughts?
