Seems to be played the way I would have, did you have a read on UTG+1?

Fold pre-flop . Otherwise fine.

God I hate flops like that. I like the play, you took a stab at the flop and turn. I can't believe he checked the river. Did he have a naked Ks, aces up, crappy 97s or even better an A with a worse kicker, or even worse AQ? You still have plenty of chips.

Looks a bit too aggressive for me. It looks like your putting alot of money in the pot with TP... Maybe I wouldnt have bet as much, but since you added money on the preflop raise (maybe a mistake since your in middle position, not late position) you were probably thinking of matching the pot on the flop/turn. Early position AJ can be folded (at a full table)

I normally fold AJo pre-flop from that position. When I do play it, I have mixed feelings as to whether to raise it or limp it. By limping I avoid scaring off the Ax players who I might dominate and get payed by post-flop....but I also risk letting players with garbage hands hit a big flop.

However, I like your post-flop play. In a raised pot you can't fear the flush too much. It's more likely that he has a four-flush than a made flush post-flop so you bet to protect your hand. Sadly, it's entirely possible that he has AQ/AK....but I bet it's more likely he's chasing the flush with a king of spades. Mathematically AQ/AK is more likely but his play seems more consistant with a chaser.
