Preflop to post flop odds...

[VorShot]

Is there a good way to calculate how possible hands are to be % wise only from from preflop to flop?

Everything i find goes from either preflop, the flop and the turn to the end only.

Here is a quick accurate estimation .

If your hand is an underdog to the river , then you must hit your hand on the flop and your opponent must miss .

This is just 1/3*2/3=2/9 or 22.22%

This works if both of your kickers are less than your opponents .

If one of your kickers is higher than your opponents then you have to make an adjustment .

Say your opponent has a-j to your k-10 .This means your opponent may hit a jack and you can hit a king and be ahead .

This will happen about 1/6*1/6 . Now add this number to 2/9 and you get the probability you're ahead by the flop .
2/9+1/36= 25%

What about hands like Suited connectors?

Suited connectors are drawing hands . The only way you can have the best hand on the flop aside from hitting your kickers is if you hit your flush or a straight on the flop. Otherwise, depending on what your suited connector is up against , you have to look at your kickers relative to your opponents kickers which I've given the answers to already .

If you have a hand like 10-9 suited , you should add about another 2% , 1 % for hitting either a straight or a flush .

So.....the odds of hitting either two pair, trips, a straight, a flush or picking up a Straight flush draw (15 outs)on the flop only are?

[jay_shark]

The odds of hitting two pair , trips is already included in my calculation of hitting the flop . For instance , if you have AK , then the probability you hit an ace or a king is around 33% (1/3) . This also includes hitting two pair, trips,fh or quads . However , it does not include the probability of hitting a flush or a straight or any type of draw .

The odds of hitting two pair or trips is around 3.5% . The odds of hitting a flush draw is around 3*3.5=10.5% . The odds of hitting a straight draw is also around 10.5% . The odds of hitting either a straight draw or a flush draw is around 20% .
