I played a very unusual hand vs MK_Ruthless, a good SSNL reg who's up 25k over 300k hands. during this session he's been winning all the big pots as well as 3betting many of my LP opens. we've played before but never tangled enough to create a lasting dynamic. he's probably noticed I've been 3betting a lot this session, but I haven't shown down non legit hands in big pots. his flop c/r is 17% over ~500 hands, fold to 3bet is about 75%

this hand happened towards the end of the session.

his flop c/r reps almost nothing, and this looks like a good board for me to cbet. I don't think there are a lot of Jx hands in his range given he flatted my 3bet OOP, and he probably slowplays his flopped sets sometimes since this board looks good for me to barrel twice. so I decided to float and see if he'd shut down on the turn. **I used my timebank before I called the flop c/r.**

when he checks the turn and shoves the river I'm really confused. If he turned a draw I'd expect him to shove the turn.. would he play KQ this way?
