I'm kind of a noob, so if this analysis is way off, please let me know.

Doesn't his line say to you that he has a mid-sized pocket pair (5-5 to 10-10). If this is right, then there is really no bluff to snap off. Even if he has a pair of dueces you are beat. If you are saying that you want to bluff with your AK, okay, but you can't really snap off a bluff, can you? Help me see what I'm missing.

Thanks
