Nc3 Bb4 {Nimzo-Indian Defense} 4. a3 { Samisch Variation, with this move White loses some time and ends up with doubled pawns and a weak a-pawn. But he has the Bishop Pair which he hopes will be worth it.} (4. e3 {Rubinstein System}) (4. Qc2 {Classical or Capablanca Variation}) (4. Nf3 {Kasparov Variation}) (4. f3 {sometimes called the Gheorghiu Variation or the Shirov Variation}) (4. Bg5 {Leningrad Variation}) (4. g3 {Fianchetto Variation}) (4. Qb3 {Spielmann Variation}) (4. Qd3 {Mikenas Variation}) 4... Bxc3+ 5. bxc3 O-O {Black has tried many things here. Castling is the 3rd most popular option and the 3rd most successful, albeit with only marginally worse stats than the other two.} (5... c5 {is the most played move with the intention of fixing White's Queenside and targeting the c4-pawn.}) (5... b6 { is the second most played option. Here Black prepares to put his Bishop on the long diagonal.}) 6. f3 {[%CAl Gf3e4,Ye2e4]} d5 7. cxd5 exd5 {[%CAl Rd5e4,Rd5c4] } 8. e3 Bf5 9. Ne2 Nbd7 {Black has almost completed his development while White appears to have moved a lot of pawns. White's center is strong and should enable him to catch up a bit.} 10. Nf4 {Moving the same piece twice while all of his other pieces remain on their home squares. Not a system to recommend to a beginner.} c5 {Black strikes at the center. With his big lead in development he really wants to open the game up and punish White for his tardiness.} 11. Bd3 {White offers a trade that would remove one of Black's developed pieces and bring the White Queen to d3.} Bxd3 12. Qxd3 Re8 {Lining the Rook up with the King although he will not have time to stop him castling.} 13. O-O Rc8 {Black will soon open up the c-file for his Rook.} 14. Rb1 { White's Rook takes the b-file.} Qa5 { Black gives up his b-pawn and allows the White Rook a spot on the 7th rank. He feels this Rook will not be able to become established there.} (14... Nb6 {would have retained Black's slight edge.}) (14... cxd4 {was also a valid option.}) 15. Rxb7 Nb6 {The Rook it appears has become trapped and White must have seen this. He is giving his Rook for a Knight and a pawn. What else has he seen?} 16. g4 {He starts a Kingside attack, using the pawns in front of his own King in the pawn storm. He must be pretty sure this attack will succeed. If it doesn't he'll be down material with a wide open King. This is why he played to deflect the d7-Knight over to the Queenside.} h6 {[%CAl Rh6g5] Black wants to secure his Knight on f6.} 17. h4 { The White King is feeling the breeze and the Black King sees a posse coming.} cxd4 {An old truism in chess. If your opponent attacks you on the flank, counterattack in the center.} 18. g5 {White pretends he didn't see it. For him it's # or bust.} dxe3 {Black ignores the threat to his Knight and insists that his attack is stronger.} 19. gxf6 Rxc3 {The Rook says hello to the Queen. Black believes he has forced White to suspend his attack which will hand over the initiative.} 20. Qg6 { White forces Black to reassess and he does. Instead of capturing the Queen he decides the better option is to resign.} (20. Qg6 {[%CAl Rg6g7] The threat is # in 1 if Black does not accept the Queen sacrifice. If he does it's # in 2:} fxg6 21. Rxg7+ Kh8 (21... Kf8 22. Nxg6#) 22. Nxg6#) 1-0
