Hand 1 : Everything is fine except river is a check - there just isn't enough value from the odd 9s/10s (i think a decent player is folding those lots) vs the times he c/calls better or c/raise owns you.

Hand 2: I'm a bit torn - on the one hand it's consistent with your line to be strong here - but I think most people expect you to jam AQ+ on that board to a raise but then again you'd be jamming most flushdraws as well so yeah I think this is fine and he folds Ax sometimes.

Hand 3 : Meh i'd just fold flop since I Don't think people are bluffing this board that often and if his range is Kx + combo draws you're pretty crushed.
