I'd have to say fold even though I sometimes like to call the two overpair all-in's with my slightly higher pocket pairs. Like it was said before, it's a coin flip, but initial percentages go your way.
Fact of the matter is, you only have 150 into the pot. To call another 4850, there's no pot odds
, and given the person didn't jump the gun and flip the AK suited, you wouldn't know if you where facing a higher pp or complete garbage.
I agree with the posts that say wait, pick your spots, and don't put yourself into a position to get knocked out unless your at least 90% sure you have the best hand.
Just my two cents.
