I was wondering about a random scenario i thought of where i cant seem to find an easy solution from the top of my head.

The szenario is 2 players reach the flop with the exact same range (booth only have AA and KK), the pot is 2bb and they are both 100bb effective and the person out of position is first to act (duh). Logically i would think the player IP must have the advantage so his EV should be >1bb, but i just dont understand where this ev comes from.

Forgot to mention that the flop is 789R
