Hero checks, MP1 checks, Button bets, Hero calls, MP1 raises (!!), Button 3-bets, Hero calls (XXX), MP1 caps, button calls, Hero calls (YYY).

River blank, hero checks, MP1 bets, button raises, hero folds, MP1 calls.

I'm perfectly happy w/ how I played the hand until the turn. I want to know about decision points XXX and YYY. Could / should I have gotten away from the hand at either of those points??

I like checking the turn K, because I'd prob get raised by any K if I led, and my goal is to see river for 1 bet. Calling first button bet is no-brainer. But then MP1 comes alive on a trap play and checkraises 2 opponents, screaming some kind of boat, and button 3-bets!! I need to call 2-cold at XXX, but pot is very large, and I've got a great draw even though board is paired. Then at YYY, it's just one more bet in a huge pot, and I do have the miracle royal draw, even though it looks like hitting a simple straight or flush is only going to cost me more money vs. a boat.

Comments? This hand was a tough one for me.
