Nf3 e6 4. g3 Bb7 (4... Ba6 { ..is a another line which historically has been the most popular. White has a lot of options here. 5. b3 was all the rage some years ago, but it is also the move with the highest drawing percentage in the position. } { [%cal Gd1c2,Gb2b3,Yb1d2,Bd1a4,Rd1b3] } 5. b3 (5. Qa4) (5. Qc2) (5. Qb3) (5. Nbd2)) 5. Bg2 Be7 (5... c5 6. d5! { Breaking with ..c5 is "never" any good if White has this option at his disposal. Now the fianchetto bishop on b7 will struggle to get active. } 6... exd5 7. Nh4 { White will regain the pawn and obtain a slightly better pawn structure. } { [%csl Gd5] } 7... g6 { [%cal Gf8g7] } 8.

The computer also fancies White's chances here as the extra pawn will count for something. }) 6. Nc3 Ne4 { As in the Nimzo-Indian, Black will attempt to control the important e4 square in these variations. If White is able to advance with e2-e4 then Black often will struggle against White's space advantage in the centre. } { [%csl Ge4] } 7. Bd2 f5 8. d5 { Decreasing the influence of Black's strong fianchetto bishop. } { [%csl Rb7] } 8... O-O 9. Qc2 Nxc3 10. Bxc3 Bf6 11. Nd4 c5 12. Nb5 Bxc3+ 13. Nxc3 e5 14. O-O d6 { [%csl Rb7] } 15. f4 e4 16. g4! { A typical break in such positions - very instructive play from Jesper. Black doesn't want to have his pawn structure in the centre destroyed, so the g4 pawn is not really en prise. } 16... g6 17. g5 (17. gxf5 gxf5 18. Kh1 { ..was a slightly more aggressive option. } { [%csl Rg8][%cal Yf1g1] }) 17... Na6 18. e3 Nc7 (18... Nb4 19. Qd2 Nd3 20. Bf3 $14 { The knight will be chased back. Taking on f3 is not an option as Black will risk ending up with a terrible bishop on b7 against White's flexible knight. } { [%cal Gf3e2] } 20... Nxb2 21. Be2 Nd3 22. Bxd3 exd3 23.

Ba4 { All of Jesper's pieces are playing, which is a sign of great understanding - Black is completely tied up and helpless, even though materially he is doing fine. } 36... Rg7 37. Rh8+ Bg8 38.
