Hand 1: Value bet dont push. You do not have the nuts and you will only be called when you are behind (in a small pot).

Hand 2: I probably raise preflop here with AJ but the check is fine. Apart from that it was played fine until the river. Should really check behind on that river. He probably wont pay you with just a pair. The turn pot is fairly large so you could argue a push but getting calls is fine since the stacks are so small that getting sucked out on and calling the river push is still EV for you. One thing to note is that many players will call the turn push with just a flush draw at 10NL with those stack sizes compared to pot size. Watch out for those players and always push against them here.

Too tired to look at the others now since its 4am here but ill probably take a look tomorrow.
