There are some programs that do these calculations but I would like to know if there is any way to do it efficiently and quickly?
I lose some chips, cause i don't make this.
There's some tips to make it more efficient and fast.
In a rapid search I found this:
1-> count your outs (cards that make your hand win)
2->the chance of win is your out multiply for 4 (you have a flush draw, 9 cards cam make you a flush, you got 9*4 = 36%)
3->calculate the odds, if the pot has 80 chips and you need to put 20 chips, the odds are 10:2 or 20% (80+20=100, 100 of total pot with your chips 20-> 100:20, simplifing this 10:2)
4->20% are less than your 36% wining hand, you shoud pay ( if the odds are more than you chance you have to fold)
OBS.: I have troubles with this too, there's no a easy formula, you will need to study a lot, others facts can modify this count, don't use only this, try to study
pot odds, implied odds, and the villain range, they can have a flush draw too, a fullhouse.
Playng against with fishs, maniacs and callstation need to the do with atentions, the odds, maybe will not has much important, try to play more tight and go loose after seen some villain's actions
