^^^^ this is exactly my point.
The counter to that though, is that the table as a whole must gain from UTG’s deviation. Imagine if we were looking at MP instead of the BB. Does he lose money overall because of UTGs nittier range? If the answer is yes, then we can extend this question to all positions other than BB’s and at some point someone must gain from UTG’s deviation or else the theory is wrong.
Thinking about it more, I think BB actually gains the most +EV from a nitty UTG open as he can get a walk, but all other positions must put money in to maintain their equity share.
So MP probably gains the least from a nitty UTG open. Or the small blind. But is this a net positive for these positions?
Or should the GTO middle position range always be +EV vs UTG’s solid but nitty deviations? Not sure we can ever really answer this, but to get everyone’s opinions would be interesting.
Can we approximate this with raise only strats where everyone is 20bb deep maybe? Then everyone can raise or fold to 3bb and 20bb
Possibly we could look in the database and compare EV when UTG opens vs EV when UTG folds, and check this for all positions. But this needs a huge sample size to be accurate. And of course we don’t have a record of the EV drop when we 3bet a nit.
I hate to post this again but it’s super relevant and the inspiration for this post:

If you see the example used in that link, and work out why SB loses EV from BTN’s deviation, I think we could get close to answering original question.
Looking at the link some more ...would it be possible that every position loses EV vs a nitty UTG open except for the BB, who gains massively?
