After he reraised the flop, I was hoping to get a cheap showdown. Normally I'd fold here, but I think a that's a leak in my game (when people put all-in pressure on me I fold almost everything). Is my play alright?
He wasn't at the table long so I don't have any reads.

Dont like your line here much - I think that a call on the flop instead of a 3bet is ok, as often fish minraise with really strong hands. On the turn I am raising all in after his weak bet - fish normally follow up min raises with the nuts with strong bets - this bet is too weak and I now think that his min bet was made with a draw.

On the river the fish has bet massivly. This is what I would have expected him to do on the turn if he had a huge hand on the flop. I fold.

Very easy fold IMO. Hes never pushing worst than poorly played straight here. Most likely your going to see a flush though.

You're seeing monsters under the bed. This is almost never KJ. A flush's much less likely because he bet turn, but it's a possibility. Reasonably, you're ahead of AT, A2, AK, and crazy bluffs, and behind TT, 22, and flushes. I call here, you're good at least 1/3 of the time.
