Hi, I download pokercruncher today and when I calculate the equity of

KK vs. TT+, AQo, AQs, AKs, AKo, AJs, A5s, I get 67.59%
If I remove AQo, I get 66.36% equity.

Is it normal that the equity of the KK goes down if I remove the AQ, since KK vs QQ is about 72%. How could it be that by adding a weaker holding to villain's range our equity goes down.

Thanks!

If you remove a hand that you are ahead the eq is going down , since there is bigger chance of you being against the other hands of that range.

This. Plus this is the poker goals & challenges section of the forum...

Hello,
(Disclosure: I'm the developer of PokerCruncher. Hope it's OK I'm adding a clarification on this.)

This is as expected because: the original range has 32.5% equity against KK (run the Monte Carlo sim long enough to converge on the stats). AQo by itself has 28.2% equity against KK; the important part: this is below the range's overall equity (32.5%) i.e. AQo is a below-average hand of the range. So if we remove AQo from the range, we're making the range stronger, so the range's equity will go up, and KK's equity will go down.

I think this is mostly the right idea but it's not "remove a hand that you are ahead"; the key is remove a hand that's below-average in the range. For example, KK is ahead of AKs, but if we remove AKs from the original range then KK's equity goes *up* a little (from 67.5% to 67.6%). This is because AKs is an above-average hand of the range (34.1% equity), so we're making the range weaker.
