Black announces his intention to play a Grunfeld instead of a King's Indian.
4 Bg5 Ne4
A viable alternative to 4...Ne4 is 4...Bg7. 4...Ne4 is preferred by about 6-1, but both moves score about the same. With 4...Bg7 black offers a (temporary) gambit, but he will easily recover his gambit pawn; e.g., 5. Bxf6 Bxf6 6. Nxd5 Bg7 7. e3 c5 8. Nf3 Nc6 9. Be2 e6 10. Nc3 cxd4 11. exd4 Nxd4 12. Nxd4 Bxd4=.
5 Bh4!
This is the "miracle ingredient" popularized by Taimanov in the early '70's. The Bishop will exert uncomfortable pressure on Black's Pawn on e7, making his development difficult.
5...Nxc3
Batsford Chess Openings also gives 5...c5 leading to an unclear position. However, a survey of my most recent games with this opening shows that Black played 5...Nxc3 in 5 out of 6 games, the 6th playing 5...dxc4 (see game 1 below).
6 bxc3 Bg7
BCO gives 6...c5 as the main move, and also mentions 6...dxc4. But I am giving this as the main line since 3 of my 5 aforementioned opponents played this, with the other two trying 6...dxc4.
7 e3 c5
7...0-0 gives up the e-Pawn after 8 cd Qxd5 9 Bxe7, but it leads to difficult play for White (see game 2).
8 cd Qxd5 9 Qf3!
This is the new move Taimanov found that lead to such success for him. If Black trades Queens on f3, Taimanov showed that White gets the better endgame. (see game 3).
BC) gives 9...Qd7 10 Bc4 0-0 11 Ne2 cd 12 ed Nc6 13 0-0 e6 14 Bf6 Bxf6 15 Qxf6 Qe7=, or 9...Qd8 10 Bb5ch Nd7 11 Ne2 cd 12 ed 0-0 13 0-0 a6 14 Bd3 Qc7=.
Hartston, in his book on the Grunfeld (written in the days of descriptive notation), gives, in the last continuation, 13...N-B3 14 KR-K1 R-N1 15 P-KR3 P-N3 16 P-QB4 B-N2 17 P-Q5 and White is better. Hartston actually advocates Black delaying ...Bg7, and playing ...e6 and ...Be7 to equalize.

This game, played today vs. ArgoNavis, shows the interesting play that can flow from the Gruenfeld.

Here I go into the Bishop vs. Knight ending, knowing that in the time scramble to come I will be able to make moves easier than he will. At this point he has 1:08 left and I have :53.

I hit the draw button here and shouldn't have, because I had 3.2 seconds while he had only 1.2. I can use pre-moves here for the most part, moving my Knight back and forth, while he has to worry about checks and attacks on his Bishop.
