Cardodds

Cardodds is the ratio between the cards that helps you and the cards that dosnīt help you.
Suppose, for example you have klA klJ on hand and it is Ruk-KL6-kl9-sp2 on the table. Now, if the last card, the river, is another clubs card, you have a flush.
There may be nine clubs cards in the deck that can give you a flush. The other 37 cards in the deck gives you not flush. Short odds are therefore 37 to 9 or 4.1 to 1. (24.4%) You will hit the flush almost every fifth time. The other four times you fail.

To quickly calculate the cardodds before the fifth card, you look at how many cards to help you, ie how many outs you have to hit. For example, you have two spades in your hand and the board have two spades and two cards of other colors before the final card will be posted. There are thirteen spades in total in the game and since there are four visible, there must be nine left to help you.
Before the river, you should then take your outs and multiply by two (9 x 2 = 18). Add 1% if you started with over six outs. This gives you 19% chance of hitting the flush.

Cardodds before the fourth card

It is relatively easy to calculate the cardodds after the turn. But right after the flop, it remains of course instead two cards that can help your starting hand.
Ex. from a couple to three of a kind (eg, 9-9 with a flop of Q-7-3) have a card, the odds of 11 to 1 (or 8.4%)
Ex. ladder, (eg KQ with a flop of Q-5-C) 2.2 to 1 (or 31.5%).
Ex. to flush (eg ru7-Ruk with a flop on ru2-ru5-KL3) 1.9 to 1 (or 35%).
Ex. with a stright flush draw (eg hj9-hj10 with a flop on hjJ-SP8-hj8) 0.85 to 1 (or 54%) chance of improvement for at least stright.
To quickly calculate the short odds before the fourth card, you can only count how many cards to help you, ie how many outs you have.
For example, you have two spades in your hand and the flop has two spades to. There are thirteen spades in total in the game and because you have four visible, there must be nine spades left to help you.
Multiply your outs by 4 to get the percentage of how much chance you have of a hit. (9 x 4 = 36). If the number of outs is higher than eight, subtract one from the equation. That way you get 36-1 = 35. This means you have 35% chance of getting into the flush.
