Sage vs Nash

I had a question for you all as I have started to play hypers, when I was playing heads up at about 8bbs I would just go into push fold mode and used sage.  Eventually I started to play sng mtts.   However I am back at husngs now and had the question about sage and nash.  I have herd differing opinions on which to use, but it seems like much of the video's I view many talk more about nash than Sage.  Can anyone give an explnation as to why nash is now looked at as more accurate than sage, where in the past nash was incorporated as too loose?   Jut curious if anyone could also chime in a which one they use a 8bb also would be great, and I know you have to adjust based on opponet, but in many cases at 8 it is just push fold.

http://www.husng.com/content/game-theory-optimal-and-exploitative-play Basically, the Idea behind SAGE is that it is way more simplified and therefore easier to calculate. NASH on the other hand is a equilibrium strategy. If you are in the position to PUSH according to NASH, NASH always (!) assumes that your opponent calls according NASH. If you are about to call according to NASH, NASH does asume that your opponent always (!) pushs according to NASH.NASH therefore is not exploitable. On the other hand, this means that we surrender counter-adjusting and therefore often give up EV. If you know your opponent is open-shoving 10BB deep with AK, AQs, TT+ only, this is clearly not the pushing range your NASH calling range is based on and therefore NASH can force you to make a -EV play.Basically NASH (and that is also true for SAGE) should not be used, unless you give your opponent an Edge over you.  You than can (at least by useing the NASH-pushing-chart) reduce his edge to 0.Is it possible that you confuse SAGE and Chubkov? PS: here (http://www.husng.com/content/sitngo-wizard-comparison-nash-end-game ) you find another interesting discussion.
