Sitting in a sng down to last four players. Need one more to exit and then everyone else will get paid. stack size is 10x BB. Dealt AK in SB and raise 3xBB, chip leader raises you All In; everyone else folds. What is your play??

Knowing the other stacks is critical as K of M said. 10xBB sounds relatively small. If it is small, and close to another small one, then raising was a mistake in the first place. You want to complete and see the flop, fold if its raised.

If your stack is small and 4th place, then I agree you have to play it to the end. You are a coin flip away from being a pretty solid 3rd vs ready to blind out.
