Tough spot. Calling and winning would be great but it will not happen that often. I think you should look at $EV because cEV is useful when you are still far from the money. Approaching the bubble you need to account for the higher risk. Getting paid does not decreases the bubble factor down to 1.0 but remains slightly higher and you have to use only $EV for the bubble and ITM imo. Also, once the first bubble bursts and goes down close to 1.0 (but not equalt to 1.0) it starts increasing again aproaching the FT.
All that said I would fold AKo although I am not sure I would be able to do this because I am not that good I want to be. Yet hopefully
