How accurate is the Poker Odds Calculator?

I just attempted to use the poker odds Calculator. I entered in the following hand:

As 6h vs Jc 2c
FLOP: Kc Qc Qh

first calculation said: 49.6 to 50.4
recalculated several times: one went to 42.3 to 57.7

That seems like a bit of a difference to me. I was just wonderring how accurate is this calculator and shouldn't the result have been the same on each calculation with no changes in the cards?

Thanks,

nope, because all the calculator does is run the hand 100 times and then tells you the results.

you'll never have the same thing happen everytime, so it gives you a rough estimate...
that hand is just about a coin-flip anyway, so why the hell you even calculating it =]

the results aredifferent everytime but the % should remain the same, no?

I agree with Crock - 7.3% is too much of a variance to render the calculator workable.

well it should be exactly the same percent each time, shouldn't it?
a hand's strenght will not change if put against the same hand on the same flop...

NOTE: Results may differ if you rerun a calculation using the same hand. This is because the figures are the result of a Monte Carlo simulation (sampling from the deal of a few thousand random hands), not an exhaustive enumeration of every possible flop.

Winning poker is not about catching cards, it's about catching pots!

love that quote.


but as tazz was saying, the % it gives you is not the % of card possibilities that will allow you to win vs % of card possibilities for the other hand to win..

it just runs the hand over and over and over and over and gives you the out-come.

ran it 500 times, hand A won 300, hand B won 200.... but there are more than 500 possibilities....

and 7% is big, somewhat, but look at the hands there..... a flush draw with lows.... ace high..... 9 clubs for the flush, a jack or a deuce wins it for hand A... but if its a 10 - J on the turn and river, then hand B wins..

You have 3 (since the club is bad for hand B) 3's, 4's 5's 7's 8's 9's 10's = 21 + 2 queens and 3 kings 2 aces 6 deuces = 30 cards that will help....

but then lets say a 6 of clubs comes on the turn... any other 6 or queen will give you the boat....

i mean.. there are just way to many cards and card combinations that could give either hand a win... the flush draw is the only one of the two hands that actually has the possibility of seeing a turn card that would give it a little bit of an edge...

the A-6 has no one card on the turn that could give him an edge.... the J-2 can at least hit the 2-3-4-5-7-8-9-10-J are all cards that would give j-2 an edge.... but then again, even that 10 or J runs the risk of a straight...

hmm i never knew that
i thought they used some kind of formula or equation to figure it out

that calculator uses the monte carlo method. some however do it mathematically

I noticed the same thing about my odds to win hand quiz. I ran them again and got different percentages the second time. The one I use does about 1 million hands to come out this the odds of win lose or tie.

So how do you calculate the odds by hand without a simulation anyone got the math or a link to information to learn

....google ...for odds

rufcut;
if you're talking about preflop odds, it's pointless to try to calculate them in your head - all you have to know is the odds of certain kinds of hands vs. certain other kinds.
(ie pocket pair vs. smaller pocket pair is roughly 4.5 to 1, pocket pair vs. overcards is roughly 1.3 to 1 [not sure about this one, but roughly 45% to 55% i think])

If you're talking about post-flop odds, do what wsorbust said or search pot-odds and drawing odds here on CC. I think there's actually an article about odds. You should come up with a few threads about how to do it; I don't want to rewrite what's been said before.

Thanks for the info ChuctTs.
As for poker office wsorbust I downloaded the trial version, works well just does not support enough sites but the prog is great.
