After the evaluation of your hand and your opponent’s hand, you need to count your own outs and in case your winning chances are less than 50 % you should not continue the attack. In case your winning chances are more than 50 %, you should re –raise. Take into consideration that the cards which give us over pair should not be mechanically counted as outs. For example: In case you have an Ace of spades and a King of spades, during the pre –flop you raise and get one call; the flop is 2 of clubs, 7 of spades and Jack of diamonds, your opponent plays check, you place a bet and get a call; the turn is 10 of spades and your opponent places a bet. It seems the situation is quite simple – you have 9 cards to a flush, 3 to a straight and 6 overs i.e. you have total 18 outs. But never forget the hand of your opponent – this means that the overs are not to be considered as absolute outs and in case a King or an Ace is revealed, your winning chances are less than 50 %, let’s say they are about 33 %. Then the number of your outs should be calculated as follows:
Σ (outs) = 9 (flush) + 3 (straight) + 0, 33×6 (overs) = 14
In other words, your real winning chances are 9 % less than they seem to be at first (4 outs are approximately 9 %, 1 out is about 2 %).
