From the Opening into the Endgame – Alapin Siclian selection

I have always been tempted to adopt opening lines that take the game straight into the endgame, since that would, at least in theory, both allow me to practice my endgames skills, and utilize my opening preparation to control the nature of resulting play. Here is one example of such an "opening to endgame" transition that I came across recently:

Benjamin, Joel - Serper, Grigory

1. e4 c5 2. c3 d5 3. exd5 Qxd5 4. d4 Nf6 5. Nf3 e6 6. Be2 Nc6 7. O-O Be7 8. c4 Qd8
304
9. dxc5 Qxd1 10. Rxd1 Bxc5 11. Nc3 O-O 12. a3 b6 13. b4
305
There have been a number of games in this theoretical opening/endgame position. This game and the following ones present some typical ideas for White – pressure on d file and play for queenside passed pawns.

Finding The Winning Attacking Idea

In the following game, I could only find a draw in a position where a computer discovered that White was completely winning. Would you be able to figure out how to develop the initiative?

How to attack with Isolated pawn – games by Pavasovic

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
