0.5/1, I'm pretty TAG or actually nitty, I don't cbet a lot and bluff and have about 150BB behind and a tourist UTG player has me covered, he limps UTG and has been playing pretty loose calling AI with draws on the turn, opening JTo from UTG and keeps buying back in. There are 3 limpers in front, I raise the button with Qs4c to 300, the UTG limp reraises to 800, I take time and call. everyone else folds. there is a decent chance that UTG's range is capped but the issue is that he's loose and doesn't fold draws
the flop is: 4s5s7c (pot 1750 minus rake), I bet out 600, he double CR's me now to 1800, I hesitantly call after a long time.
turn: 4s5s7c9s (pot 5350), I instantly go AI for 4400 and swing my remaining stack forward.
Now the player does all kind of angle shooting at me banging his chips on the table trying to get a response, he takes 15 minutes and finally calls and says he wants to gamble. He says that I wouldn't bet so much with a flush but bet less. he hits an ace on the river and takes all of my money. I may have overestimated my fold equity, he would call AI with 100bb stacks with draws on the turn and buy back in.
The mathematical probability that he has the A or K of spades overall seems low, though when he does call the flop it probably goes up somewhat.
