Well here's one approach. Using ranges in my response to Jon Locke, and taking out 66 from all opponents to make the math easier:
Against BB, we are a
42.31% underdog when called.
Against MP, we are a
48.20% underdog when called (this number is a lot higher than it should be since MP is not overcalling with AK and may not even call with that hand).
Against the fish, we are a
70.59% favorite when called. If we include J7s, J6s, J5s, J3s and J2s to make my range more consistent that number drops significantly, to 62.61%.
Notice in our unrealistic hypothetical where overcalling ranges are the same as calling ranges (and we ignore card removal), our river bet will make 3BB's (.4231 x.4820 x.7059) =
14.4% of the time. We will lose 1BB (1-.144) =
85.6% of the time. Ignoring all other scenarios (which makes this analysis kinda absurd but whatev), that's an EV of -.856BB + (.144 x 3) =
-.424BB
And of course the above begs the question: what about all the other permutations, eg when BB folds, MP calls and fish calls, or when BB folds, MP folds and fish calls, etc. Well to factor that in then we DO need to include the entire ranges that all these guys are taking to the river on this board so we can guesstimate how often they're folding on the river. Not an impossible task, but not a fun one either, and there's really no intellectual payoff either imo, since to me it was already intuitively obvious we should not value bet the river vs 3 opponents, and what little number crunching that has been done points towards that same conclusion.
