I normally just estimate, there’s no real time to be precise.

If my odds to improve to a leading hand are good enough I call.
If I think my opponent is on a draw I bet enough to offer them a bad call.

lol ok, how do you calculate them though.......what do you do? and please be more precise, what do you consider "good enough"?

Miss J - I recommend you go read on the topic. Lots of good info out there.

The skinny of it is that you look how much the bet you would have to make is compared to the size of the pot.

Example: On the turn in a 3/6 FL hold'em game, it is $6 to you to call. The pot (which includes the bets in front of other players which have not been slid into the pot) is $60. This is giving you 10 to 1 pot odds ($60 pot / $6 to call). If your nuts draw is better than a 10 to 1 to hit, it is a +EV move to call for $6.

It is after the flop, there is $20 in the pot preflop. You have 8 Heart 9 Heart.

Flop A Club K : Heart 2 Heart


OK, you have 9 outs for your flush and cant expect to really have any more. So you have a 36% chance of seeing a heart on turn or river. So, it someone bets $2 on a $2/$4 limit game, $22 in the pot, you have 36%, you have good pot odds.
Now, lets assume it is 10/20 and it is $10 to call. Now there is $30 in the pot when action is on you, assuming heads up, you have about even pot odds. Since that $10 might win you $30 and you have 36%. Now, if you assume that the player will bet after the turn or river, you would assume that your $10 investment will net you more than $30, so you have positive implied odds.

Now, turn-no heart, no pair. Still have 9 outs, but now only 18% chance of hitting. Lets say no one bet the flop, still $20 in the pot. 2/4, someone bets, $4 to call, $24 to win 4/24=16.67% and you are 18% win, you are again even to positive. 5/10 game, $10 bet, now $30 in the pot, 10/30=33%, you have negative pot odds since you are only 18% to hit so you should fold.


So basically: amount call/pot size% < % chance to hit the winner then positive pot odds

now there's an answer with some detail. thank you.

Sorry Miss J I know I was very brief but when I get into an answer I usually end up re-reading it and delete loads because I think it’s to specific and doesn’t allow for other factors. I’d rather be generic and vague then fall foul to the deadly “it depends”.

I’d advise you do some googling, the subjects pretty big and you’ll get lots of good examples, much better thought out than I could write Smile
I’d also recommend The Theory of Poker, Sklansky has a very mathematic style and cover pot odds better than the other books I’ve read.

Memorize these numbers:
-a flush draw is 4:1
-an open ended straight is 4.5:1
-a gutshot straight is 11:1

If you have a draw simply ask yourself: can I make the corresponding number based on draw times the amount it is to call? That's the quickest way to do it.

Another example:
You get A Spade T Spade in the BB. There are 4 callers + the SB + your BB which puts 6 small bets in the pot. The flop is 7 Spade 8
Heart 6 Diamond . SB checks, you check, the next guy (who is extremely passive and never bets anything worse than two pair) bets everyone else folds and it's back to you. There were 6 small bets preflop and now there is one more so you're getting 7:1 on your call. You are a 10:1 dog to hit your draw so you have bad pot odds.

But it occurs to you that you will win 2 big bets (4 small bets), possibly more if you hit on the turn. You're getting 11:1 implied odds so you have good implied odds.

I thought a gutshot was 11:1?

You're 100% right.
