What´s the point? When you´re playing poker of course you may not know what your opponent is holding. But remember that one of the most important part of the game is to read your opponent, to guess what he may be holding. You cannot count your outs if you don´t know what you need to beat your opponent. For example, let´s say you hold Ac 7c and the flop comes Ah 10c 5c.
Now the way you count your outs changes depending on what you think your opponent is holding. The outs are not the same if you think that your top pair is good enough to beat your opponent, or if you think that you need just the flush or two pair to beat your opponent (because you may guess that he has top pair with better kicker).
When you count your outs you´re counting the cards that make your hand winner, but winner against what? Against your opponent´s hand. The same hand can be a winner or a loser depending on what your opponent is holding.
That´s the reason of why the
odds calculators need at least two
hands to calculate the odds. Odds calculators calculate the chances of winning of each player.
You asked if there is a program that says what are your chances depending on just your cards. The answer is i don´t know, but it doesn´t matter. As i said before, your chances of winning doesn´t depend just on your cards, they also depend on your opponent´s hand. A nut flush for you can be a full house for your opponent. But if your are looking for an odds calculator that you select your hand and then you ask for example what are the odds of making the straigth with that hand after the flop or turn, you´re looking for something that you really don´t need. To calculate your hand odds, use the rule of 4. Just count your outs and after the flop you multiply them by 4. After the turn it´s the same but instead of multiplying your outs by 4, you multiply them by 2.
For example, let´s say that after the flop you have a flush draw. You have 9 outs. You multiply 9 x 4 = 36. You have 36% chances of making the flush.
Of course that odds are not exact, because you don´t know if your opponents were holding some of your outs. Math in poker is not exact, because poker is a game of unknown variables, so use the odds to know approximately where are you standing on the hand and if it´s correct to chase or not your draw, but don´t make every decision according to them. Math is a very important part of your arsenal, but is not everything. And that´s the reason of why you can just use the rule of 4, because you need approximately odds, not the exact ones.
ps: Sorry for all of you community but i´m back! If you want to know how my trip to
brasil was, i can tell you that i enjoyed it very much. I didn´t play so much poker because we didn´t have time. We made 2 sit & go, and i finished 1st and 2nd.
ps2: can someone make an article of odds? I think it would be really helpful. I would like to make it, but i´m not an expert and my english is bad.
