Wow this hand just had me scratching my head the whole way. OK, I know I usually tell people you need reads to make the whole hand analysis more beneficial, but by the preflop action (3 posters!!!) you should realize I just sat down at the table intending for it to fill up, so unfortunately I do not have any reads.

OK, I started to analyze my play in this hand, but I think it might be better if the other posters analyzed this hand and tell me the good and bad of it before I delve into any logic I had for this hand.

I'll keep it simple.

Cap the flop.

Lead the turn.

Call down a turn raise.

[brettbrettr]

Cap flop, lead turn, pray to fill up on river.

edit...read the post wrong

You gotta cap the flop and lead the turn. I thought that you might be going to check/raise the turn when I first read it, but you didn't (I prefer capping). Backing down to a flop 3-bet when you flop top two is pretty weak. You must ram-and-jam here, you won't find a better place to do so, but one where your equity could change so quickly.

Yeah now looking back not capping the flop and leading the turn seems pretty weak.

My logic was to check raise any turn, however, when it got back two cold to me on a 3 flush board I didn't know what to do so I just called.
