Hand #1: Played perfect if you're going to limp with 55 in EP. I personally raise it up anywhere, but that is just different PF play.

Hand #2: I like the fold. You only have $1.25 invested an this guy clearly wants to play a big pot. Your hand isn't getting any better. Half the time if you boat he makes a better boat.

Hand #3: I check behind here too. If you get raised you have to puke/fold. Be glad you hit the J and took down the pot.

I want to see the really bad ones that you speak of though. I know hands like these didn't cost you 2 buyins.
