I had a similar situation happen in a B&M tournament a few weeks back.. it was a full table, so there are differences, but I had QQ in EP, and raised about 4X the BB. The chip leader 2 seats to my left re-raised all in, and the action got back to me. In this situation, I have to ask myself.... Is this something this guy would do with JJ or worse? Especially because you are in a $50 SNG, as compared with, say, a $10 SNG. I ended up folding, (face up), and he flashed me KK. You have to think BEST CASE SCENERIO you are a coin flip v.s. AK, and worsecase scenerio you are as 41/2 to 1 dog
