Correspondence/Werfen (5) 1994


1. d4 Nc6 2. Nf3 d6 3. d5 Ne5!?

3... Nb8 transposes to Modern Defense or Old Indian lines but with some loss of time. The advance to e5 in this position is a bit dangerous due to the White check at b5.

 

4. Nxe5 dxe5 5. e4 e6!?

If Black doesn't trust the lines that follow, he could play 3...Ne5 but consider something like 5... Nf6 6. Nc3 a6!? (6... e6 7. Bb5+ Bd7 8. dxe6 fxe6 ) 7. f4 (7. Qf3 e6 8. Bg5 h6!=) 7... Qd6 8. Qf3 e6 9. fxe5 Qxe5 10. Bf4 Qd4 11. Be3 Qe5 12. O-O-O Bd6 unclear.

9. Nc3!

The idea is to castle queenside quickly with an attack for White. Other moves may also work but are much more difficult to fathom.

a) 9. c3 Qd3 (9... g6!?) 10. exf7+ Kf8 11. fxg8=Q+ Kxg8 12. Be3! (12. Qf3?! Qc2 13. cxb4 Qxc1+ 14. Qd1 Qxb2 15. Qd5+ (15. Qb3+ Qxb3 16. axb3 Kf7 ) 15... Kf8 16. Qc5+ Kf7 17. Qd5+ Kf6 18. Qxb5 Qxa1 19. O-O Qd4 20. Qxb7 Qb6 ) 12... Qxe4 (12... g6 13. Qd1) 13. Nd2 Qxg2 14. O-O-O

9... Qd4 10. Qxf7+ Kd8 11. Bd2 Ne7!

Not 11... Bxc3? 12. O-O-O (12. Qf8+! Be8 13. O-O-O+-) 12... Bxb2+ 13. Kb1 Kc8 14. Bg5 Nh6 15. Qxg7 Rg8 16. Rxd4 Bxd4 17. Qxh6+- 1-0 Schmidt - Somerbauer, Werfen 1992 (43)

 

12. O-O-O Be8 13. Qxg7 Rg8 14. Qxh7 Bg6

Perhaps playable is 14... Bd6!?

 

15. Qh4

Perhaps White must try 15. Qxg8+! Nxg8 16. Bg5+ Ke8 17. Rxd4 exd4 18. Nb5 with at least four pawns for the piece in a difficult ending to assess.

 

15... Kc8 16. f3

16. Bg5!?
