Hmmm, is folding really 0EV? If you fold a +EV situation, you are essentially "losing" money because you didn't take the money you could have won.
Folding is always and forever 0EV. The value you expect to make off folding is 0. You gain nothing, lose nothing on future rounds. Remember, the money you have already put in the pot is no longer yours and every decision is irrespective (mathematically) of previous rounds of betting.

I understand your point, and to an extent it is correct, but in mathematical terms folding is always 0EV. If youve passed up on a +EV situation, you have lost value, that does not mean youve made a -EV move. A -EV move is a move you make (such as a call) that is expected to lose you money long term. A fold can never lose you money because the money you've put in the pot is no longer yours. Its a little dicey, I know.


So in that case doesn't the doubt have to be put in the EV calculation? So if your doubt that your beat makes you think it's -EV then it's -EV. I'm sure Hollingol gets it wrong sometimes but you have to take your best most educated guess.
Absolutely, IF you can quantify that doubt incredibly precisely. The point being, most people are just not that good at doing it.

Do you honestly believe you can go 49.35% of the time he beats me, but I win the other 50.75%? Being off on your estimate as much as 1% of the time turns a winning move into a losing move.

But as far as I can tell you are saying that more times than not when you make a questionable decision its -EV?
ABSOLUTELY. The human psyche is INCREDIBLY good at deceiving itself and justifying a given action unto itself. Think of any and every crime committed "in the heat of passion." Or the real good cops, the ones you really want in uniform, who at the end of a police chase beat the living shit out of a suspect and then lose their jobs over it. Thats their head deceiving them into believing an action is justifiable when its not. The human mind is very very good at that.

You really do have to train yourself out of it. The best you can hope to do is be cognizant of it.

Its not a function of the decision itself, as your statement seems. Its not that everytime you make a questionable decision its automatically -EV. No, but you need to be aware that your fundamental "humaness" is going to scream "CALL CALL CALL" at you when you really really shouldnt.
