Poker math practice (example)
Hey guys!
Im trying to get a hold of the math but idk if I'm right or wrong. So it was this 888 poker and I was wondering if anyone can correct me if im wrong. Its a simple of example of pot odds and wether or not to call. Ok so pot odds I got was 13 to win with 7.4 to call So 13:7.4 which is roughly 1.8:1 so roughly 36% And hand odds are I'm assuming they need a straight so they're open ended so 8 outs. 47:8 and I just learned I'm supposed to reduce to 39:8 so that gives us 4.8:1 so 17% See this is where I get lost. If what I just did is correct in ratio form. The math indicates a call and then in % form it goes against a call. So if anyone would be kind enough to take a look at this and show me where I went wrong it would be a huge help. Thanks a lot

You could always use an EV calculation to see if the call is + or  EV
https://www.cardschat.com/pokeroddsexpectedvalue.php Formula is ~ EV = (%W * $W) – (%L * $L) % you win i.e. 36%. Amount you win $13 % you lose 64% Amount you lose $7.40 So = (36.00% * 13.00)  (64.00% * 7.40) = 0.06 so its slightly minus EV

IF you have 8 outs (8 outs x4) you roughly a 32% chance of making your hand. You need to be getting about 31 (about 21,000) in the pot to get the correct odds to call. While these aren't exact figures, they are close enough to make the correct call or fold and can be done very quickly in your head. But, there are other bigger problems with this hand. You are counting outs that really aren't outs. Generally people count outs to the nuts. You are counting outs to the sucker end of the straight. If the villain has a hand like Kh Qh you lose a lot of outs, hands like Ah Kh have you in worse shape (you are only like 20% to win). This is a very easy fold.

I'll fold on this situation, because 36% you will win and the rest you will losse. Its hard to risk on this situation , but if you feel that your outs will come , and you made call , and you win this hand... you're nice.
Anyway Fold on this situation.

Easy fold, just not enough money in the pot to risk 1/2 of your stack.

E.g. you are 2/1 or 33% to win If you played the Hand 1000 times and it cost you $1 every time, you would win approximately 333 time and lose 667 times When you win you get 2/1 odds so would get $3, 333 times approx $1000 return The times you lose, lose $1 which will happen approx 667 So it costs you $1000 and get $1000 back so breakeven The actual breakeven equation is Risk/(Risk + REWARD), so 1/(1+2) ~ 1/3 or 33% If you are getting 33% its breakeven. If you are getting greater than 33% i.e. Calling an all in Bet with a flush draw 36% its above breakeven so a call and if less than 33% its less than breakeven so a fold

why you get here is 17% others is 32% something? 17% is you dealt with 1 card 32% is dealt two cards so correct all combo C (47,2)=1081 card you want C(8,1)X(C39, 1)+ C(8, 2)=340 so chance 340/1081=31.45%

I did read the topic, but I’m unsure what I understood, not that I understood the question too well =) so from the beginning:
From thepokerbank.com: “Remember! You should only call if the pot odds are greater than the "card odds" (odds of completing your draw).” Here pot odds are NOT greater than card odds, thus fold. 1.8:1 < 4.8:1 You can think it like this, with card odds, if you have one outer your card odds are 46:1 then obviously greater the card odds number the worse case we have in our hand. So big card odds bad> we need even bigger pot odds to compensate. Not sure I got the question right, it’s all math, even though odds format is kinky.
