hand 1. is push/fold. if we call we have half of our effective stack committed so if we're going to play we want to make sure draws pay. looks like a fold though.

hand 2. is really player dependent the whole way. you can check the turn vs some, bet vs players who call light. also on the river, will this player slowplay a set and then shove on this board? its a fold vs a good player.

hand 3. raise this gay blocking bet. we often have the best hand, but we're folding out hands we beat with a raise. that is a very scared bet.

hand 4. fold. its a very strong bet, he isnt vbetting a weak ace this strong. all you beat is a missed straight.

hand 5. fold, hes taking a very strong line and there are no draws. you can also c/c turn, c/f river unimproved.

if you break these hands down in to individual posts it would be easier to respond to.
