I agree with bobbyi on hand 1. Not a lot of hands you'll fold and it'll probably take another bullet to fold AK and AQ and they may not on a blank.

Hand 2 is OK but I'm not sure it's any better than calling down. Check the river.

I don't like hand 3 much at all- what kind of range do you put this guy on after his flop 3-bet? I think you have very little fold equity and he's blocking any free card attempts too often for this to pay.
