This is a $400 buyin WSOP circuit event at Coconut Creek Seminole Casino in Ft. Lauderdale, Florida. We just made it to the money (top 25) and there are now 24 players left. Current cash is like $750, 1st place is right around $20k.
I'm on the SB with 200k, blinds are 2500/5000 with 500 ante.
Folds around to hero, I raise to 13k with A♣
:. The villain in the BB calls. He is the biggest stack easily at the table and maybe the tournament with about 400k.
Flop is K♣
Hero checks. Villain bets 13k. Hero calls.
Turn is A
:. Hero checks. Villain bets 19.5k. Hero raises to 56k. Villain tanks for about 30 seconds and calls.
River brings the 6♣
. Hero checks. Villains tanks and shoves.
What is the play here? Is the turn check raise ok? Do we call or fold the river?
