Standard Value bet or Check

Nope, I'll keep the moniker: I thought they both had >1K. Didn't notice OP only had 300. Since this is the case, I agree that a bet would be better, because now the chance that you are ahead is almost 100% since villain would certainly bet if he beat you expecting a crying call from OP and also because there is no fear of a c/r. The only question now is how much to bet. Personally, I like something like slightly under half pot. Hope to get a crying call from a weak hand or induce a c/r bluff. I doubt he is calling a full pot sized bet with too many hands here.
