I’ll make just a few assumptions.
I consider the avaliable stats in HM2 HUD: VPIP, PFR, Fold/call to Steal, ReSteal (all stats avaliable from any position), 3B ecc.
– the “Steal from Button” (but also the “steal from SB” and CO) stat could provide a quite correct Oppo’s Push range.
– The “Call to steal”, “Fold to steal” and “Resteal” (especially from BB, but also from SB) stats could provide a realistic Oppo’s call range on my push.
Obviously it could be reliable only with a considerable statistical sample, so it could be done only with those Oppos that I play often with; for example it could be 2-3 colors for the ranges depending on how many hands can be considered or could be done only with a specific (maybe selectable) number of hands played.
However, I’m neither a pro nor a programmer; these are just ideas that I have (and could be a starting point as an absurdity) and I propose them absolutely without any presumption. I don’t know if it can actually be done. However, if there was a way, I think that also other SNG players might appreciate it.
