And, it's already been said, but include much more information. We can't give you a broad answer here because "it depends" [img]/images/graemlins/smile.gif[/img] on particular circumstances. Here, it's vital for us to know how big the stacks are to give a good answer.

I'll give you a couple of my thoughts. If BB has a good hand here, why wouldn't he just check and let you bet, since you were the preflop raiser? Usually, if there is a draw on the board, i'd suspect that the extra large bet was just to buy the pot with some draws. But here, there are no draws, so it comes down to a particular player and his tendencies.

In a small stakes cash game i'd more readily think i was against a really big hand here, and the BB is hoping you or someone has an ace and will pay off his two pair or set here.

If I was shortstacked id have to call, but if we were deepstacked, i'd let it go and look for a better spot.
