elohah: As I suspected upon first seeing it, this game does appear to be the swansong for my earlier recommendations in the g3 system, which can be reduced to rubble with some slight tweaking of Black's play here.
For I have recommended EXACTLY the plan that Grandmaster Ye follows in this game, and it's worthlessness would be more than apparent had Black in this game
(1) NOT 'posted up' (with ...Ne5) but instead purposely played for the key ...d5 break with ...Rfd8 and later ...Nb6! Prior to that, you quickly chase off the c3-knight with ...b4. It CANNOT go to a4. I've just determined that on Skij. For Black will PIN with ...Ra8!, then play ...Ba6! and ...Bb5! (forcing b3 or c3) He will then capture the knight with his QB, and enforce ...d5 again.
White's whole operation, with the cipher pawn play on the Kingside is an absolute bust.
And the key lesson from this game?
Since I have repeatedly said that 8 a4 is necessary, yet Zapata's 11...Rab8! shows that it's still worthless, since ...b5! simply cannot be prevented!
So - one more time - Zapata could have IMPROVED his play here by RAPIDLY playing ...b4! and then ...Nb6! And I do believe that 16...Rfd8! (saving a tempo) was better than 16...Rfe8.
If White then SWITCHES his play after f5, and plays fe and Bh3, in order to PUNISH ...Rfd8, THEN (and only then), does Black POST UP with ...Ne5!
Thanx. Have a nice day.
