So I realized where pokerterms.com had gone wrong in their evaluation of the so-called “computer hand” of Q7o.

As the legend has it and my own evaluator showed, Q7o is the hand just above the 50% mark in heads-up matches. Q7o has a very slight statistical edge (winning 50.56%) against random hands when the board runs out to the river. The entry for “Computer Hand” at pokerterms.com, however, claims that the Poker Stove application “Q-7 shows 51.77% equity versus a random hand.”

The problem arises from a misunderstanding by the folks at pokerterms.com of what Poker Stove calculates. As the Poker Stove FAQ itself states (emphasis added):

What does PokerStove calculate?

The values generated are all-in equity values. This is not the chance that a hand will win the pot. Rather it is the fraction of the pot that a hand will win on average over many repeated trials, including split pots.

So what we’ve got here is a sort of apples and oranges comparison. The “computer hand” specification is precisely about how often a hand will win. Poker Stove is making an entirely different evaluation.

Don’t believe everything you read on the internet.
