"ILP,
FPS much?"

The answer is no, when I play poker I am genuinely trying to make the best play I can each stage of every street. I do not always succeed in this effort but thats my overall goal.

"This is the kind of thing that can give you a very marginal additional edge when you apply it correctly, but will cost you a lot more if you misapply it."

Even if this statement is true it doesnt add any insight to this dicussion. What youve just said can apply to many decisions in poker.

Obviously knowing when to execute this type of play will not add that much to our edge beucuz the right spot to deploy this play doesnt come up that often but doesnt this kind of thinking lead to a slippery slope? In other words, isn't it possible that this approach, of passing up several potentially profitable plays simply becuz our edge is small in each isolated case, can lead to a non-insignificant decrease in our overall winrate?

Shouldnt we all have an extensive playbook that covers all contingencies no matter how rare they may occur?

"Btw, I'd never fold a showdownable hand if I was Heis in this spot because f-villain (unless there was a ton of history)."

Well then that proves that this play should not be run against you.

BTW your statement that this play can cost you alot if you misapply it is not really true if one is putting the requisite thought process into making this play. Mistakes will be made cuz were human but this spot will not come up often enough for these mistakes to be costly.

It should be quite rare when it's correct to value/bluff raise the river after being check/raised on the turn. IMO, given that were playing from the BB, we have the right board to make this play. Can Heisen bet/fold here? Do we have the right image? Those are the questions I am not sure about, but I still love the OP's thought process. If there's ever a time to run this play. This could be it.
