Yeah gotta be honest, I would probs wait a couple of minutes, and then start raisinig, at least then you can say you gave him time to get back.
Mikey, that is exactly what I did. I waited a couple of minutes and then decided if he wasn"t back by then I"d get raising. So I waited the two minutes and no sign of him.
After about 90 seconds of raising, he returned and stack sizes were 16k and 5k.
My heads up was awful, bad cards, couldn"t hit a flop, couldn"t bluff when not hitting a flop, and he played very well. Stacks were back even, when I got pretty much coolered.
Holding AJ, board comes 3 7 J 7 A
Gradually the chips went in during the hand, but majority went in on the river. He was holding J 7.
At the time of him sitting out, blinds were 100/200 I think. As has been commented on, I considered this a "community" game and that"s why I chose to do what I did.
In the end, it was the wrong decision "results" wise, and an extra two minutes of blind stealing would have left him very very shortstacked, but I felt it was the right decision, and also a decision that I would hope anyone would make in APAT league game for example, although, maybe my hopes are a bit high there.
