flicked on to the open highlights this afternoon and Norman was talking through a hand. one of the players was four to the flush on the flop and Norman was taking through the pot odds. he was saying the player was 4/1 to hit his flush. with two cards to come that's not quite true is it? I wonder if Norman meant specifically 4/1 to make his flush on thenext card or if he was forgetting to double it.
I remember pot odds being a mystery until someone put it in these simple terms. numbers are approximate but easy for quick reckoning.
If I'm doing this wrong please correct me.
number of outs x 2% x cards still to come
so for a flush draw on the flop 9 outs x 2% x 2 cards
9x2x2=36% or a touch better than 2/1
big difference to 4/1.
obviously the other consideration is that if you don't hit on the turn will you face another bet and are you likely to be getting the 4/1 you need to call that bet.
so for example
flop is
you have

and you are absolutely convinced your oppo has AK
pot is 500 and he bets 250
you are calling 250 to win a pot of 750 so you're getting 3/1 which is right by the 9x2x2=2/1 but wrong for the 4/1 Norman was talking about.
however. if you call on the flop and your opponent bets the pot to shut it down on the turn you're in trouble. now you're calling 1000 to win 2000. thats 2/1 but now you're 4/1 to hit.
that's why I like live poker better than online. it's subtle phyical clues you get as to whether your man will be moving again on the turn or not that aren't there online (for me at least)
I think an easier rule of thumb is "the rule of four".
On the flop, multiply your "outs" by 4, the answer is the % chance you are to hit.
Thus, 4 to the flush on the flop, so 9 outs x 4 = 36%, = (as near as makes no difference) just over 2/1.
On the turn, it becomes the rule of two. 9 outs x 2 = 18%, about a 9/2 shot.
At least, I think that's right......approx.....roughly......near enough.....
