Keep in mind the following hands come from a guy that plays a 100NL that's not as aggressive as yours. Anyway:

Hand #1: You need to raise the flop. This looks like a standard flush draw trying to get a cheap turn card in case he didn't hit, but he did anyway.

Hand #2: I really don't see what you're beating here. What's his 3-bet calling range. I would put him on TT+, AQ+ (wider?) On the flop he knows you didn't call the reraise with AK. So if he has QQ-KK I don't see him pushing as he has to know he's only getting called by a better hand. I can't see someone trying to make a move in a reraised pot like this.

Hand #3: Would this guy only call with TT-JJ in the SB? This looks like a "even a shitty player gets a good hand too" kind of spot. Seems like a total set line but that turn push is odd. Have you seen him make moves like this without a legitamit hand or a FD? If so I call. If I don't have that info I sadly fold.

Hand #4: He's taking a weird line but he could have been getting tricky with AA or something against the initial raiser thinking he wouldn't have gotten much ction with it otherwise. Or maybe he was counting on you making the squeeze. I have seen people do this with AK lots too though. Whatever the case, I think 99 is behind his range. I also can't see a 19/10 trying to teach you a lesson so I think he needs credit for a hand.

Hand #5: This is good assuming you put him on a float or a Q type hand. His turn is weird though. He plays this hand totally different from the other possible FD board in Hand #1. His turn bet is weaker than in the first hand. Would he be bad enough to telegraph his hand strength like this? Does he float reraised pots in position?
