#1) I get all in with AK vs AJ. We both have $200 to stat and there is $15 in blinds in the pot. For ease of math, we'll say Im a 70-30 favorite.
You win $215 70% of the time, and lose $200 30%;
So your expected return is (0.7*$215)-(0.3*$200) = +$90.5 each time you play this hand.
#2) I get all in with AA vs KK. Same stacks and blinds. Total pot is $415 and I put in $200 of it.
This is 82/18 so
(.82x$215)-(.18*$200) = +$140 each time you play the hand.
You played the hand once each - so your expected EV is +$230.50
Your actual winnings were only $15.
You have $215.50 sklanksy/icy bucks to spend on complaining about it !
