Let's see if I can work out the maths myself:

AA against 88 on a 6-max table has a 80% of winning, that's 1:5 you're going to loose.

If we think both have 100BB that makes your

equity +80BB over time for going all in in this situation. That's for a single run.

However, the second run has an additional 5 cards removed from the deck, so villains probability changes to maybe 22% in the second run. That makes it roughly 20%+22% = 42% for villain not to loose his whole stack. The chances of villain not hitting in either run is roughly 0.8*0.77 = 61%. Let's settle for a 60% chance.

The chances of villain hitting both runs is 0.2*0.1 = 2%, effectively making quads.

That makes hero's equity: 60% to win 100BB, 2% to loose all, 38% to split. Does that mean the total equity is (0.6*100) + (0.38*0) - (0.02*100) = +58BB

This is not regarding the 2% chance of both hitting a set in the same draw and not accounting for the rake.

Does that mean that although you loose your stack less often with aces, you split so much more often that your equity gets ruined????

Thank you very much for all mathematically gifted people to revise the calculation !!!!

Edit: I am disabling run it twice immediately just in case my calculation is right. It would mean that RIT only favors recklessly loose opponents.
