I made the 1/2psb on riv cuz I thought I would be paid off by trip queens, a very likely holding, but didn't really have a gameplan against a raise (from a fullhouse).

If yo'ure gonna bet the river, push. He might call with trips, but he's only raising when he has you crushed. That said, bet less on the turn, try to price yourself in.

Both.

Preflop, raise or fold with KJs. Open limping in early position is bad IMO.

Flop is fine, but another possible line is to make a smaller bet for a multiway pot with your draw, but you don't mind winning it right there.

Turn you are now heads up and out of position and the board has paired and you could possibly even be drawing dead. I think that a check or 1/3 pot bet is good here.

River, not much else you can do at this point.

Guess you lost to a full house or quads, although you don't post the result.

Well even if I raised pf (which I don't really like to do, althought I dont like the limp too much either, maybe fold from now on lol) he could have called.

He showed 10 10 on the river. Guess I was just meant to be stacked?

IMO i like the way you played the hand. The bet on the river is fine too, as it often wins against other drawing hands who strike out.
IMO, once the pair hit the board, you were drawing for a winning NON NUT hand at best. You KNOW that a full house could be lurking out there. An important question, easily overlooked , is "What did i put him on?"
If you just sat down at the table, your call is justified.
If you've been there a while, and your opponent has been playing soundly, and not too many hands, then your call is a mistake.
If the guy has been playing loosely, then again, yoiur call is sound.
IMO.
MTFBWY May The Flop Be With You. lol
