Hand 1 I re-raise bigger to setup a no-brainer flop push if the limper calls.

Hands 2 & 3 are both foldable pre-flop.

It's funny that I play so much looser than you, but I'm a total nit with AK/QQ against people who don't re-raise much.

When you read posts involving bigger games and get advice from people in them, understand that pre-flop and to an extent post-flop is so much more aggressive in those games. I think folding a good hand becomes less of a big deal as you move up because bluffing frequencies make it less of a mistake.
