d4-d5 pawn break as a theme from various openings

I wrote a couple of books on this subject – one about pawn breaks in general, and one about positions with isolated queen pawns (where pawn breaks are common) specifically, and these topics still come up in games that I study.

 

Here are a few more examples with some instructive positions and ideas highlighted:

Zvjaginsev, Vadim - Popov, Valerij
Moscow-ch blitz   2004.09.05 , D42

1. e4 e6 2. d4 d5 3. Nd2 h6 4. Ngf3 Nf6 5. Bd3 c5 6. c3 Nc6 7. O-O cxd4 8. cxd4 Be7 9. Re1 dxe4 10. Nxe4 Bb4 11. Nc3 O-O 12. a3 Be7 13. Bc2 Re8 14. Qd3

267The early h6 move seems entirely out of place in the current structure.
14. ... Kf8 15. Bf4 b6 16. Rad1
( 16. d5 exd5 17. Nb5 Ba6 )
16. ... Bb7 17. Qd2
268Setting up the not so subtle threat against h6.
17. ... Ng8
( 17. ... Rc8 18. Bxh6 gxh6 19. Qxh6+ Kg8 20. Ng5 Nxd4 21. Bh7+ Kh8 ( 21. ... Nxh7 22. Qxh7+ Kf8 23. Qxf7# ) 22. Nxf7# )
18. d5!
Taking advantage of Black's last move which defended h6 but gave up control over d5.
18. ... exd5 19. Nxd5
269Black gave up because there is no good way to meet Nc7. If Rc8 then Bf5 adds fuel to the fire.
1-0


Spassky, Boris V - Mnatsakanian, Eduard A
