Interesting #Poker hand from a $3/$5/$10 NLHE game. I’m holding 6♠4♠. EP opens to $30, I call in LP, BTN calls. The flop is Q-6-5 🌈 with one spade, giving me middle pair and a backdoor flush draw. Everyone checks. The turn is A♠, giving me a pair and a flush draw. The initial raiser checks, I check, and the BTN bets $120. The original raiser calls, and I check raise to $525, turning a relatively weak made hand into a semi bluff. EP folds and the BTN calls. My thinking is straightforward, but there are several layers to it. The A♠ is a card that interacts with the range of hands I can credibly represent, and my raise puts pressure on medium strength holdings. At the same time, I have additional equity when called, although raising into two opponents makes this considerably more ambitious than it would be headsup. The river is the J♥, and my flush misses. There’s $1,150 in the pot, my opponent I has around $750 remaining. I check, and my opponent moves all in, presenting me with an interesting mathematical and psychological decision. I’m risking $750 to win a final pot of $2,660, meaning I need to be correct only about 28% of the time. That’s a fascinating concept because I can be wrong more than 7 times out of 10 and still have a profitable call. But mathematics alone cannot tell me whether my opponent is bluffing frequently enough. Now we get into something even more interesting, card removal. Holding 6♠4♠ means my opponent cannot hold either of those cards, which changes the combinations of hands available to him. My spades remove some of the missed flush draws I would actually want him to be bluffing with. In other words, the very cards that gave me additional equity on the turn can make my hand a less attractive bluff catcher on the river. Ideally, when calling a large river bet with a marginal hand, you want to block your opponent’s strongest value hands while leaving his potential bluffs unblocked. But blockers aren’t magic since they only matter when the hands you’re removing would realistically have taken the same betting line. There’s also the question of what my opponent is representing. After calling a substantial turn check raise on the turn, which value hands would shove this river, and which missed draws would have the courage to bluff? More importantly, would this particular player actually bluff often enough to justify a call? I eventually fold, and my opponent turns over 7♠8♠, a missed straight and flush draw. My pair of sixes was good. Naturally, my first reaction was to wonder whether I should have called. But the more interesting question is whether I should have taken the initiative and shoved the river myself. Against his actual holding, a shove certainly wins the pot, but that doesn’t establish whether bluffing would be profitable against his entire range. In fact, there’s an argument that my biggest mistake may have occurred one street earlier. By check raising the turn, I created a large pot with a marginal hand and entered the river without a sufficiently clear plan for the different cards that could arrive. A good poker decision shouldn’t simply consider what happens immediately, but also the difficult decisions it might create later. The most dangerous mistake is allowing the final result to rewrite the quality of the original decision. Just because my opponent happened to be bluffing doesn’t mean calling was necessarily correct, and just because I folded the winner doesn’t mean folding was necessarily wrong. The objective isn’t to win the hand you’re playing. It’s to make decisions that would be profitable if you could play that same situation a million times. I’ve come to appreciate that this is one of the deepest connections between poker and investing. Both reward intelligent decisions over time, but neither promises to reward them immediately. And in both, one of the greatest dangers is becoming more confident simply because you happened to get lucky. 🌹
