Hand 1: This is probably bad since it makes it so easy for a set/straight to stack you, but I find myself often just pushing the flop here. I think it's fine how you played it, though. Depending on what I thought he had, I might just fold to the c/r, even against a player of these stats. EXTREMELY read dependant spot.

Hand 2: Lol, ouch. I don't know. Flip a coin?

fwiw, it's pretty obvious you're beat, but I usually call just so I can see what the other guy has. The alternative is to convince yourself that he has the bare ace of hearts, which is a possibility, but unlikely IMO.

Hand 3: I don't dislike the preflop raise against some players, but against a good TAgg, I'd probably just respect his blind here.

Post-flop is beautiful. High variance, but I'd play it the same way.

Hand 4:

[obvious]he doesn't have KQ, dude.[/obvious]
