I suppose that catching bluffs is the sexiest move in poker. It can also be the stupidest when you are wrong, which I am a lot. The problem is that being good at catching bluffs isn’t about making the biggest calls, it is about folding when you have the worst hand and calling when you have the best hand. If your a total station your bound to catch a bluff, but your not going to make a lot of money.

When deciding to make a hero call or not, I use three factors: Possibilities, Logic, and Emotions.

1. Possibilities: Is there actually a hand he could have gotten to this point, where he is betting or raising, that is not a nut hand? For example, you are OOP in a 3bet pot (heads up) and cbet a K72 rainbow board. Your opponent calls. Turn comes a 3. You check and he bets. In this situation, the only way your opponent is bluffing is if he decided to call the flop with a total air hand with the intention to take the pot down on the turn or river,  or if he decided to turn his hand into a bluff. Both are unlikely scenarios. On the other hand, change the board to T95 two spades and you have a much different story. Now there are many hands he could call the flop with, KQ KJ QJ 87 to name a few, that would call on the flop.

2. Logic: Is there logic present that he could use that would make him decide to bluff? And is that logic more compelling or evident than the logic not to bluff? Another example, say you have called a open OOP, again heads up. The flop comes J86. You check, he cbets, and you call. The turn comes a King. You check and he bets. Because there are very few hands in your range that improve with the turn king, and some hands in his that a king improves, this card makes logical sense for him to bluff on (among many, many other reasons). On the other hand, in the same situation if the flop comes AT8 rainbow and the turn comes a T, the only logic I could see for him to use to make him decide to bluff is that he has a good draw, something that isn’t plentiful in his wide range, or that he feels I would lead the turn if I spiked trip tens, or maybe that I would fold an Ace, weak draw, or an 8 to a turn bet. Even though the logic is present, I would tend to not make a hero call in this spot because this logic is not as compelling as the logic that the turn card is good for my range and nearly irrelevant to his.

3. Emotions: Would his likely emotions sway him to bluff? This may seem hard to figure out, but it is something that can be grasped. Winning, for example, could make someone feel confident, disregard money more, and cause them to decide to bluff. Emotions can often be outweighed by strong logic. I may feel like total shit after I lose 4 buy ins in 5 minutes but that probably won’t cause me to bet that Ten turn on the AT8 board if I’m in position. It may however cause me to bluff when my logic is foggy. Fourbetting preflop is a great example. Most people do not have set rules on what hands they will 4bet as a bluff. You could 4bet bluff with J4s and it could very well be a good bluff. The logic is unclear. 4betting as a bluff at any given time vs most players could be good. So if you are feeling like someone is 3betting you constantly, you have lost a lot of money, and you haven’t fourbet in awhile, 93s looks as good of a candidate as any.

Sometimes, using these factors I can be absolutely sure with what seems like near 100% certainty that my opponent is bluffing. The funny thing in poker that much of the time you only have to be 30% sure to make a call correctly. And we are faced with this problem constantly in poker, because 99% of the time we don’t have the type of hand we are willing to get all in. Hopefully, this post will help turn this problem into a good situation.
