Hi two plus two,

I'm trying to find an equity calculator with the following capability:

I want a tool that allows you to narrow a pre-flop range to a certain equity percentile in post-flop situations (as measured against a random hand or another specified range).

For example, say I start the analysis with a 25% pre-flop range, and I choose Ts9s3d for the board, I want to be able to tell the program to restrict this pre-flop range to the best 60% of hands, in light of that board. "Best" would be defined as having the most equity against either a random hand or against a specific opponent's range that could also be manually chosen.

So...does anyone know if this exists?

Equilab, and Flopzilla as far as I'm aware, let you restrict ranges based on board interactions, but not based on percentiles. You have to manually select which post-flop hand types you want in the modified range.

Combonator gets closer to this (you are able to enter percentiles) but it ranks post-flop hands based on their absolute value (which terribly undervalues draws) or based on their equity versus one specific hand (which leads to problematic card removal effects).

Thanks.
