did I overplay this hand?

[No Nuts]

I don't know that I would have played 77 for two raises from the SB, but that's just me. Not knowing how the table is playing, two raises means my small pair gets tossed in the muck - especially because the 2nd raise is for the minimum. That just seems like a big pair asking for callers.

On the flop, it's a tough hand to play. I would also check to see what happens behind me, although you hate to give a free card and have another spade hit if everyone checks around.

UTG raised pre-flop from an early position, so he probably has a decent starting hand. It's possible he flopped the nut flush with something like AQs or AJs, but I don't think it's likely because of the flop bet. If he flops the nut flush, he probably checks to the pre-flop re-raiser to try to sucker him in. So you figure UTG doesn't have a flush.

The call by LP makes this one harder to play. It's possible he's got AQs or AJs and is smooth calling to pop it again on the turn.

The play is either fold if you think LP will slowplay a flopped flush, or raise if you believe your hand is the best.

I think LP played this one poorly - if he raises a significant amount on the flop, he might be able to push you off your hand.

All in all, it's an aggressive way to play the hand, and I don't think there's anything wrong with that.
