UB 25/50: I fold a hand (for once)

[AZK]

Hmm, not sure that I like this fold, the action is so confusing, I can understand the turn check, if he hit spades to get a call on the river, but then he checks the river, does he really expect you to fire? Most people would be spooked into checking behind. I mean i konw this isn't a bluff cause so many pay it off, but it's a weird way to play 666 or a gutter. I also don't see much point in 3betting the flop. I don't see many people calling the 3 bet.
