Made some money on this play. No read on opponent. 50NL ultimatebet. Made some money, but:

1. Should I have been in the hand in the first place?

2. Should I have been more agressive on the flop?

3. Did I have any business check-raising the turn?

I don't like playing a big pot with TP 3:d kicker in an unraised multiway pot. He could have A3, K9, 33, 98s or whatever. The fact that he's a shortstack is obviously a good thing here.

The way I looked at this hand, and maybe you guys can find the flaw in my logic: Limped in looking for a big flop, got an ok one. I'm not willing to play through as many people as that with only top pair, so I check.

The pot raise from a player an unknown player at the end is where I decide he does not have best hand. This is compounded by his lack of a PFR. Really what I see here in my mind most of the time is A with a weaker kicker or 9 something. With hearts on the board I felt I could make this pay:

On the turn I checked. The full bet indicated to me he isn't on a draw, but he thinks I could be. The club is a green light for him to bet. I felt my hand was best, but didn't want to see another card (Its debatable if I should have seen the turn), so I pushed.

Do I just have a bad case of FPS?

I like a flop check raise or leading the flop. I prefer the check raise.
