I you want to learn more about counting hand combinations and how to apply this information get David Sklanskys "Fighting Fuzzy Thinking in Poker Gaming & Life" and read pages 118-126.

The most common scenario where counting combinations can make/save you some money is when you have a set, and a passive opponent raises you on the turn when a straight card comes. Assuming he will only raise the turn with 2 pair or better, the correct move will usually be to call down since there are too many straight combo's to make a turn 3bet profitable.

Example: Passive guy(assume he will only raise TT-AA, and fold hands like K6,Q6,J6 preflop) open limps and its folded around to you in the BB with QQ, and you raise. The flop comes out KJ6, you bet, and he calls, the turn is a Q. You bet, and he raises. Assuming he will only raise the turn with 2 pair or better, his range on the turn looks like this: KQ,KJ,QJ,66,AT,T9. Counting combo's you would figure out that you are 16-9 underdog to have the best hand, therefore you would not 3bet with your set, instead you would call down unless you improve.
