When making it to the heads-up stage at the end of a multi-player SnG, blinds are high so I typically shove or fold. I think I have been open shoving too widely, though. I've been using the Push/Fold Nash Equilibrium. According to Nash, I can open shove with 76o for 10.7 big blinds and 87o for nearly 15 big blinds. While these seem too high, Sklansky-Chubukov seems too low at 2.7 and 3.8 respectively.
I'd appreciate some advice from an experienced HU player here. Perhaps recommendations for books or articles.
Thank you kindly.
