Thanks for your answers, I'm still a n00b so I'll take any advice and read it a couple of times. The table was so horribly passive that any pre-flop raise might have made me just getting the blinds. I've also seen a LOT of the I'll-play-any-suited-hole-cards-players. But yeah, I've learned my lesson. Be careful with slow-playing AA (change tables if I don't get any action).

The reason I thought he would call my all-in is that he had a flush (any will do, for these flush-lovers)

But again, this is a bad play gone terribly well. Thanks for pointing out stuff, I'll try to play it better next time

In sum -- raise preflop, bet out on the flop, make a man-sized raise on the turn, and make a callable bet on the river.
