Converter is crapping out quite a bit and is pissing me off but UTG or UTG+1 initially raised and then button raised to 21K, an initial raiser folded. So it was heads up to the flop with one all-in. Given the money in the pot okay to shove here on the flop, is this standard? Am I ever getting any fold equity here? I don't think too much is folding here. AK in the absence of no spade might lay down but what else? Would this be a solid shove on the flop or is this really my only move? I feel as though all I can do is shove here.

Hero?

With 16BB's I would shove the first time around over the original raiser. After getting 3 bet by the button for over 1/2 your stack you are pretty much committed to the pot since you called. You only have t27,000 after calling pre and the pot is t58,000.

Shove first time for sure, never folding this with your stack.
