There’s more to ev than odds.
Using the scenario of a naked fd on the turn. We have 9 clean outs. Our
equity is 20%.
The pots 3bb
V bets 2bb
Our pot odds are 2.5-1 (28%)
So we don’t have a +ev call. But we likely still shouldn’t fold, implied odds can now come into it.
We have to win 3bb more from the hand to break even on the call. So if when we hit we can win 3.5bb more from a pot that will be 7bb then we have a +ev call on average.
It’s one example from that spot where pot odds don’t tell the whole story.
