Difficult to say this considering the hands that end up being tabled, but I think this is a tight but good fold. The BB's cold call (rather than jam) is very, very often going to be AA or KK.
Agreed. Very stat dependant IMO. Our decisions effectively an all in pre from 15bb. If player 2 has an abnormally high VPIP compared to his Preflop raise we can potentially get it in and not be dominated vs his range however a lot of the time we're calling for a flip at best. On the reverse if player 7 has very similar VPIP and PFR factors and a negligible 3 bet we can assume he's only shoving with a small percentile of his top range even from an 8bb stack in late position; which is likely dominating our hand. In this scenario we're now at best hoping to win a side pot that will be less than our Original starting stack if we call.
The decsisions also affected by when the blinds are next going up based on Player 7's shoving range.
Try not to be too results dependent and just have faith in your decision making. Good fold readless.
