Introduction
In this article- Is the push-or-fold mode according to Nash ideal?
- Can a push or a call according to Nash be -EV?
- When and how you should adapt your game
- Do these adaptations depend on the size of the ICM effect (bubble factor)?
Good heads-up play is vital if you want to play SNGs successfully. As the blinds are usually very high by the time you reach the HU, you will mainly find yourself in situations in which you fold your hands preflop or push them all in - this is known as push-or-fold play.
So-called nash ranges (NRs) play an important role in this context. Since you will often be up against a fish in the heads-up, who has built his stack through crazy moves, you need to be cautious when using such nash ranges for your game.
This articles serves as a complement and an extension of the articles SAGE – Sit and Go Endgame System and Push or Fold in Heads-up.
It is not necessary to have read them in order to understand this article. The so-called SAGE is basically based on Nash equilibria; SAGE simplifies them in a way that they are somewhat easier to memorise. However, this also makes the system rather stiff.

Nice explanations, especially how +REV could include some -HEV hands.2 questions: (1) how come Nash ranges table has some minor differences compared to Nash HU charts from www.holdemresources.net (e. g you can't push 85o with ES 4BB according to latter, but you can according to the former). (2) In the chapter Modification guidelines, I'm not sure to what sentence "cases 2 and 4" in the brackets refers to - against most opponents in the lower limit STT, i think i have to apply rules 2 and 3.
Thanks for the article.
