I did not learn most of it's evaluation and I hope that learning it's evaluation will not only help Movei but also help me to be a better player(hopefully to the level of 2200 fide rating). About myself: I think that I am in the level of 2000-2050 fide rating at 2 hours per game or 90+30 fisher time control inspite of the fact that my last Israeli rating is 2103 because I have to admit that I had a lot of luck in my last tournament games including winning on time against a player with 2100 from a lost position with 30 seconds incresement only because he forgot to look at the clock). I also got amazing result of 9.5/10 against players with rating 1800-1950 when in half of these games I came out of lost positions or inferior positions. Note that I expect to save lost positions against weaker player and sometimes to win but what happened in the last israeli update is clearly above my expectations and normally I do not expect to get more than a draw in endgames when I am a pawn down and it happened twice.
