I'm not seeing how the K changed anything at all here.

We can rule out KK for either villain I'd say and if one has KT then they have us the whole way down and would have stacked us anyway when we pushed to a flat call.

If they have the straight then they got there on the turn and we should have heard about it on the turn.

Really don't like the check on the flop and not too happy about no raise on the turn either to see what the 1/2 psb meant.

As played with stats I'm calling here and expecting to see MP2 overvaluing AK and SB showing up with anything but most likely a bluff hoping to buy the pot with his image.
