This. I'm shoving turn.

Correct. However, if you have the best hand OTT & your V has a draw, what kind of draw does he have?

Say you have KK & the board OTT is J974

Now based upon the betting & the flop texture, you do not believe V has a set, nor did he flopped a str8. You also bet so much OTF, that this V would never have paid to see the turn with nothing but a flush draw. You also do not believe he flopped two pair because you bet your draws OTF & he would have raised.

When I decide how much to bet OTT on this board, when I consider myself to have the best hand, I assume V has close to the maximum outs possible. That would 78, JT, etc.

In those 2 examples V has 5 outs to 2pr+ & 8 outs to a flush [our K is a ]= 13 outs. Whether you add the 3 outs to the gutshot when he holds JT depends on whether you want to narrow his range down to 1 specific holding or not. Of course, 86 also gives he 14 outs, so 2 specific hands that gives V more than 13 outs.

So, no matter what V has, we "know" [but really assuming] that he has 13 outs at best [maybe] & no matter what he holds, it's a pair & a flush draw. So his 2 cards are accounted for.

At the table I'll ask myself how many times 13 goes into 44 = 3.4 times.
Really it's 3.38, but I'm not going down to the 100th at the table. I know that I'll have 5 left after 13*4 & 13 almost goes into 50 four times.

One of those times he'll make his hand, so he's a 2.4:1 dog.

This is much more accurate than the 2x rule, where it would be 13*2 = 26% or ~3:1 dog.

Having an accurate estimate of V's odds to make his hand is extremely helpful when he's short-stacked. Then you can bet an amount, that if he calls & makes a hand OTR that you can't fold to, the amount of his bet OTR will be small enough that he will not realize >2.4:1 on the money he put in on the turn & he is a long-term loser in that scenario.

Say the river came with the 6 & you're not convinced he has 76s. Maybe he's bluffing. Maybe he has JTs & knowing he can't win at showdown, tries a bluff. You can still call & deny him the proper IOs on the bet he called OTT.

It's been working for me for years. I am charging them a hefty price OTT, but when they are on "entitlement tilt" & haven't seen a 13 out draw in hours, they are thinking this is their pot of gold & can't fold. And we want him to call because we know we are a long-term winner.

When your V is deep-stacked & not the type to donk bluff on the river when he misses, you can entice him to call with a smaller bet that still denies him proper IOs so that you can get a call, because you can safely fold OTR.
