Nf3 { More usual is 2.Nf3. The clue is given that White may need even play c4 } 2... d5 3. e3 { The Colle System. White hems in the c1 bishop but often it will go to b2 later, to help exert control over the key e5 square. Annotations by Kingscrusher. Video at: https://www.youtube.com/watch?v=mZhMCIxNzYs } 3... e6 { The most common move here. Black is often wanting to fianchetto his c8 bishop to try and exert control over the e4 square. } 4. Bd3 { One of the ideas of the Colle System is to try and support an eventual e4 push. } 4... c5 { [%cal Gd3e2] } 5. b3 { To fianchetto the c1 bishop. This will then exert influence over the e5 square. } (5. Be2) 5... Be7 6. O-O O-O 7. Bb2 b6 { Black is aiming to restrain or dissuade any e4 from White by placing the bishop on b7. } 8. dxc5 { Quite often White has played c4 or Nbd2 here } 8... Bxc5 (8... bxc5) 9. Nbd2 Bb7 { Black is locking down against White playing for e4 } 10. Qe2 Nbd7 11. c4 (11. e4!? dxe4 12. Nxe4 Be7 13. Rfe1 Qc7 14. Rad1 Rad8 $10) 11... dxc4 12.

Rac1 Nf8 { Black has a simple aggressive plan of Ng6-h4 here. White tries to reinforce the g2 pawn in advance now } 17. Qe1 { This makes it possible to play Bf1 to defend the g2 pawn against Ng6-h4. Additionally black has to keep an eye on White potentially playing b4 } 17... Ng6 18. Bf1 Ng4 19. Nb5 (19. Qe2!? { Technically more accurate to be able to answer Qg5 with Nf3 } 19... Qg5 20. Nf3 Qh5 21. h3 Nf6) 19... Bc6?! { There is a very precise move in Qg5 here with the idea of Nf4 - see side variation } (19...

Qd2 $15 { Technically black is slightly better overall with the bishop pair being black's trump card. }) 20. a4 Bd5 (20... Bxb5 { Although in some way tempting to double the pawns here, Black has to be concerned about White's dynamic possibilities such as Qc3 looking at g7 here. } 21. axb5 Rxd1 (21...

Rxd4?! 26. exd4 { Whites pawn duo can be fairly dangerous here. }) 26. g3 Ne5 27. Bg2 h6 28. f4!? { The issue with this kind of move is that it weakens e3 and White's kingside generally. } 28... Ned7 { The c5 blockade square beckons here } 29. Na7 { White immediately threatens Nc6 here } 29... Qa3 { This move encourages White potentially to take on d7 but Black will get e3 with check in that event, making the position unclear. } 30. Nc6 (30. Rxd7 Nxd7 31. Qxd7 Qxe3+ 32. Kf1 Qc1+ 33.

Also note that after Qxa2 Ng4+Kh3 White does have one last Qb2+ but after Kg6 there are no more checks as the b6 square is covered. } 0-1
