View Full Version : $EV Diff miscalculation for tied hands

I am noticing that HEM is calculating my $EV Diff incorrectly for certain hands--I'm not sure if the problem is limited to just this, but I've noticed a problem when two hands likely to split are shoved in.

For example, the hand below I shoved AK and was called by AK. We each had two suits so I had exactly 50% equity. However, it was 95.6% likely we would split the pot.

When I went into the hand replayer and ICM, sure enough it says my "luck" was 63 cents above my EV, which is correct given my tournament structure. However, the main window (and therefore my graph) is displaying the hand as $EV Diff = -$14.54.

I'm assuming the problem is that HEM is assuming when I get in an AI situation that 50% equity simply means I have a 50% chance of doubling up and 50% chance of busting. See the attached hand history and screen shot:
