Flop full house, fold turn. Am I weak/tight?

[NIX]

I fold too, but I definitetly 3bet the flop. Having SB slow down on the flop with a flushdraw or middle pocket pair would suck.

Well played every street. I don't think it matters much whether you call or 3-bet the flop. I think you make more on non-diamond turns if you just call the flop.

Lots of people in on this hand. The flop contains a pair of jacks that could easily go with another hand. Diamond possibilities could give you action but they will probably come along anyway. You played right by jamming this early getting the most out of the hand. I would call the turn and river bets if the action was light.

The reason I jam early is because an ace, king, queen or case jack (as what happened) could come on board making your hand second best.
