If we want to find out where we stand, just bet fold. I think putting in 2 more BBs is too much.

His check means one two things, like fizzle suggested:

1) A slowplay. Likely KK or QQ, maybe retardedly AA or AK (seen it before)
2) A hand like 99 or JJ... maybe an overplayed AJs or AQ and the K scared him? (usually a K doesn't scare a guy willing to cap AQ).

If we check/call, it should only be because we think we have the best hand. It's unlikely here. If we think the chances of being ahead + chances of sucking out is good enough for the price we're getting, I'm willing to hear those arguments. However, if that's the case, we can't check/call the river too. We have to fold if he bets the river, too. We'll almost never see a river bet from a hand we beat.

Bet/folding is good because it gives us fold equity for the times he has JJ. It also means we only put in 1 bet when way behind.

If we bet and just get called, then I think I'd probably check/call UI, because now I'm fully in "wtf?" mode and want to see his cards.
