I mucked this and it was a pretty big mistake. I thought it'd be marginal because most UTG pushes are, but shit, I found out this push is unexploitable.

what I mean by unexploitable is that regardless of what the others are calling, absolutely regardless (they could be calling 100%) it's a +EV push.

In fact, it's +EV for all of the following: Push hands: 55+,ATo+,A9s+,KQs (10%)
