Here's a move I've had mixed results with. The idea is that you continue to fire into a straight that hits on the turn even if you don't have it.

My conclusion up to now: It's usually a good move if you only get 1 flop caller. An obvious pre-requisite is also that you routinely bet strong draws.

I'm not really sure to what extent it depends on the board itself, as there are several possible draws on most boards. For example, K65. 4 is the scariest card here probably. I guess that one is probably a check-fold, since it's going to be rare that they have 43. But I think 7 and 8 are pretty bettable. Also, if the board is rainbow, the straight becomes generally LESS bettable.

I think my main problems with this bluff have occurred when I did it with more than 1 caller. It then becomes VERY risky if almost any straight hits.

"Also, if the board is rainbow, the straight becomes generally LESS bettable."

Can you explain this a little more? I would think a rainbow board might cause your opponents to believe the chances are greater that you have the goods and not some combination of flush draw + pair(s).

Well, it's the only draw they can really have.

Admittedly, they may be calling with top 2.

Returning to the example of K65 board (assuming rainbow). Let's say I bet KK OOP and get 1 caller. That call almost has to include 87. If it's 2-flushed, then it's not at all improbable that they're calling with the flush card. I think if the flush draw misses, it's probably still worth firing at an offsuit 4 or 9 on the turn. If it's rainbow, then I don't see what else they can really have (possibly K6 I guess) but a straight if a 4 or a 9 hits.

I think I'd still probably try taking a shot at any card but a 4 or a 9 with only 1 caller on that board (rainbow version) and holding top set. With a 4 or a 9, I'd probably be inclined to just check-fold if they fire back pot (?).

i think a lot of this depends on the villain.

since you're really only semi-bluffing (you have outs to the boat and maybe a turned flush draw), good players would probably have to have the nuts plus redraws to really like their hand enough to raise.

True, which also makes firing bullet number 3 questionable on a call if the board doesn't pair. Against good players you also have some fold equity against non-nut straights.

One other thing against LAGs: If, on the K65 board, you have to fold your set too often after checking a 4 or a 9 on the turn (i.e., they're going to attack a check consistently), you can slow them down by check-raising them when you make the straight yourself.
