id raise/call hand 1. you can raise fold if for some reason you think this person is totally incapable of bluffraising

bet or checkraise or whatever in hand 2 but definitely be aggro, especially trying to make the pot hu. this deep you want to make sure you dont get str8 over str8 or flush over flush and you can also get a lot of folds from hands as strong as KQ QJ

hand 3 preflop flat is fine i guess. float flop usually. def fold turn
