ok, i pretty much crush 3/6 6 max so ill go against the grain here...
hand 1...Fold, let these other morons be the fish. Your drawing period...your 9 hit may not be good even, running flush is a low percentage out, the pots small, ditch the hang wait for a good spot to cast again...
also note, if he has AA or KK which he is playing like, his boat smokes your flush, that sucks, thats why we dont get into these hands...

hand 2 - i like this, but i may just check call river...hes showing ultra aggression, any read?

hand 3- fold this preflop, hitting a Q or 4 puts your hand into an even crappier position that it already is. also, your draw may likely be a split...

hand 4- call here and take notes...
