1.e4 Nc6 2.d4 e5 3.d5 Nce7 {As discussed on 12/13/2001, Black can now choose between a King's Indian structure (d6, g6, Bg7 (or Bh6!?)...to be followed by f5) or a setup involving Ng6 and Bc5 or Bb4. The latter plan is probably more common, and is the path this game takes. MB} 4.Be3

{White tries to keep Black's bishop off c5 - a very sensible strategy. MB} [ 4.Nf3 Ng6+/=] 4...Nf6= 5.f3 Ng6 6.c4 Bb4+

{The Black dark-squared bishop comes to life despite 4.Be3. MB} 7.Nc3 b6 [ 7...Bxc3+?! MB 8.bxc3 b6 9.c5! MB {White doesn't give Black time to seal the position with d6. Black may be in trouble because the game won't stay closed and White has the bishop pair. MB}] 8.Qd2 d6 [ 8...0-0 9.Bd3=] 9.Bd3= Bc5

{Black wants to trade his 'bad' bishop for White's good bishop. After the exchange Black will be able to use the dark squares. MB} 10.Nge2 Nd7 11.g3 {White tries to keep the Black knight out of f4. MB} 11...Bxe3 12.Qxe3 Nc5 13.h4 {White tries to crowd the Black knight. MB} [ 13.b4 Nxd3+ 14.Qxd3 a5 15.b5 {Black is at least equal. MB}] 13...Ne7 14.Bc2 a5 15.b3? MB

{I don't like this move because it weakens a3 and because it facilitates Black opening the a-file. However, it's hard to avoid because the White c-pawn needs to be protected against, for instance, ..Ba6. MB} [ 15.0-0-0 0-0=] 15...f5

{A thematic pawn lever in 'e4,d5 vs. e5,d6 positions'. MB} 16.exf5 Bxf5 {Black has to be careful that White doesn't use e4 as an outpost for his knights. MB} [ 16...Nxf5 17.Bxf5 Bxf5 18.Ne4 Bxe4 19.fxe4 0-0=/+

White's e-pawn needs watching and wherever the White king goes it is likely to be drafty. MB}] 17.0-0-0 Bxc2 18.Kxc2 Qd7 Black plans a4

19.g4 0-0 20.h5 [ 20.Ng3 {White attempts to use his positional trump, control of e4, but repositioning the knight weakens White's hold on d4 and gives Black time to break through. MB} 20...c6 21.h5 b5
