"ahead on the flop"-equity?

Schpacko · #1 07-26-2007, 06:50 AM

Like most of you, i use pokerstove to evaluate the equity of a hand vs. a specific hand or a range of hands.
Is there a way to find out the probability that my hand is ahead on the flop against a hand/range?

by "being ahead" i mean an equity of 51% or more.

That does not appear to be possible with PS.

There just isn't any way to stop it 'half way' as it were.

Any other programs out there?

Stove works for this.

put the flop cards in under "board", select a hand for one player, and pick a preflop range for the other. Good work as usual, qpw.

So how do you get PS to evaluate the probability the hand is ahead "on the flop" as OP requested, rather it being ahead the end?

Yes, you really don't seem to be getting this, do you?

The OP was asking a question, not answering one.

You claim that what he wants is possible but you still haven't explained how you get PS to give to an evaluation of the probability on the flop rather than on the river.

You've just been rude (again), but do not appear to have provided the required information.

No, I did, you just don't understand it. His equity on the flop is equal to his equity in the hand overall. If he has 51% equity on the flop, preflop, on the turn, whatever. Doesn't matter. He has 51% equity in the hand. You can't have a showdown without all five on the board cards at the end.

Board: 7c 8c 3s
Dead:

equity win tie pots won pots tied
{ AdAh } 43.737%
{ Tc9c } 56.26%

T9c has 56.25% equity and is ahead on the flop.

Instead of AA, if Tc9c were against about the top 10% of hands, it would be around 60% equity.

Having the leading made hand at the moment (in the case with AA) is not the same as having most equity in the hand.

OK, maybe i used the wrong word. So for clarification:

I have XX, villain has YY.

There are Z possible flops

on how many flops am i ahead (probability of winning >50%)
on how many flops am i behind (probability of winning <50%)

For that, you can run it through Stove the same way but have to add on an extra step.

Run your calc then eake the total number of possible 7 card combos (hand + board) and pretty much divide them up proportionate to win % - different than equity since sometimes the hands will tie.

In the AA vs T9s example above they can't tie. So T9s is ahead ~.5626 * number of combinations, well over 100 million IIRC.
