Generally when we think of manipulating pot size, we think of playing pot control when we have a hand that we want to showdown cheaply or trying to inflate the pot when we have a monster. But there are times when you might want to build the pot in anticipation of a bluff on a later street.
For example, let’s say you raise 76 on the button and the BB calls. The flop comes AKx, and you decide that unless he check-raises the flop, it would be a good time to double barrel him. He’ll fold a lot of better hands on the flop and even more on the turn. What’s the correct bet size for the flop?
Strange as it may seem, even though you are bluffing, you want to minimize your fold equity on the flop. This is because you know you are going to fire a second barrel on the turn. Thus, any time your opponent calls the flop with a hand that will check-fold the turn, even if that hand is better than yours (which it pretty much always will be), then you gain. You should choose the bet size that will get the most money out of your opponent’s range for check-calling the flop and check-folding the turn.
Here’s another example from a hand I played at a 3/6 deep table today:
I opened to $21 with 5s 4s on the button, and the SB raised to $66. We were $1200 deep, and he’d been 3-betting me a lot, so I called with intention of messing with him on a lot of flops.
The flop was Js 9s 9c, which was pretty good for my purposes. It was tough for my opponent to hit, and even if he did call me, I had outs. With $138 in the pot, stacks were a little awkward for me to shove over a flop bet, but that was my play. Then my opponent made a small bet of just $78. It was now out of the question for me to shove, the risk/reward just wasn’t right, but I wanted to get the money in on the flop, with me making the last bet, of course.
So I decided to min-raise to $156. If my opponent did choose to call with a pair, there was a decent chance that I could take the pot away later or hit my flush. But if he had nothing, which I figured he would most of the time, then I thought he would either fold or 3-bet bluff me. Sure enough, he clicked it back to $234. Now, the pot was plenty juicy, and I moved all in with my flush draw. He folded, and I took down a nicer pot than I would have gotten if I’d just tried to maximize my fold equity on my first bluff raise.
