how'd daniel calculate 7d8d is 53.48% fav. vs 2c2s

In his answer to Quiz#7, he listed a bunch of preflop odds about 7 8 against a variety of hands. For example,

vs 2 2 53.48%

probably used an odds calculator

You can find one at cardplayer.com if you want to use it for your future references.

Yes, I know, there are a bunch of online pod odd calculators you can find and they are very useful.But in live casinos, you don't have those available. Unless you are a math genius like Gus Hansen, how could you figure those preflop all-in odds? Is there any simpler way to find out, like the 4/2 rule (which doesn't apply to this one)?

some of them you just memorize

forgot where i heard this... but heres a rough estimate that i use to find odds... lets do a pair to an overpair..you have 88 i have KK... you have 2 outs, with 5 cards to come.multiply your outs with the number of cards to come, double that number and add a % to it.. and it should come out pretty close..so with your 2 outs x 5 cards to come (10) x 2 = ~20%... which leaves me with ~80%..if im not mistaken, an overpair is a 4-1 favorite to win, so it comes out about right..

The thing is so many situations are analogous, and the pot odds set by betting imprecise enough to make knowing the general situations well enough all you need.So create a list of scenarios you need to know the odds of, esp. preflop, check each part of that list, and think as groups of situations, not a hand vs. another hand. Then memorize.For example, JTs is the same as 78s vs those deuces, etc.

Unless you are a math genius like Gus Hansen, how could you figure those preflop all-in odds?There are about 10 situations that matter odds-wise.Knowing that 78s is better against 22 than AKs by a few percentage points is fairly meaningless.Having some idea how well two overcards do against two undercards on the other hand is usefull.

math genius? hahahahaha OP: I think Negreanu uses poker probe, but maybe he's upgraded to another calculator by now.

so if I have AQ and you have 99 I have 6 outs x 5 cards is 30 x 2 is 60% AQ over 99? dosnt seem rightyoure 60% to hit your AQ, add in the odds of his possible trips, str8.....

[augmented 0]

yeah basically its like you are 60 percent to hit your hand, but he is 20 percent to hit his (2 outs times 5 cards times 2 percent). so about 40 percent, then add in your straight possibilities and it works out to about 57/43 him.

I sincerely doubt that anyone can do those calculations on the fly. What people are describing are highly simplified versions of the actual calculation. All a player needs to know is a figure that approximates the relative strength of their hands. Anyone who's in poker should know all the relevant odds off the top of their heads anyways.With one, or even two cards remaining, it's pretty easy to calculate the probability of a hand winning against another hand. With one card remaining, you need only know the number of cards in the deck and the number of "outs" (or cards that'll keep them ahead) that remain in the deck. Each additional card to be drawn doesn't just add one more calculation, though. The complexity of the calculation shoots way up for every additional draw in a not-so-linear fashion.
