1. An attempt to deviate from theory

  1. 1. d4
    After 1. d4

    We play ♞g8-f6, developing the kingside knight

  2. 1... Nf6
  3. 2. c4
    After 2. c4

    We undermine the center — ♟c7-c5, putting pressure on ♟d4. If White is interested in fighting for an advantage, they will have to play ♟d4-d5, advancing the pawn and seizing territorial superiority.

  4. 2... c5
  5. 3. d5
    After 3. d5

    By provoking the pawn advance, we sacrifice a pawn — ♟b7–b5 with the idea of undermining the support of ♟d5. After this, we reach the starting position of the Volga Gambit, or Benko Gambit.

  6. 3... b5
  7. After 4. cxb5Black to move.
    At the board4. cxb5
    After 4. cxb5

    The magic of the Benko Gambit doesn’t end here! We play ♟a7-a6, offering White another pawn with the idea of further developing the ♝ with tempo to a6, regaining one of the sacrificed pawns!

  8. 4... a6
  9. 5. bxa6
    After 5. bxa6

    If White is aiming for an opening advantage, they should accept the gambit by capturing the second pawn. We will always have time to recapture the pawn ♟a6, so for now we focus on developing the kingside by advancing ♟g7-g6.

  10. 5... g6
  11. 6. e3
    After 6. e3

    If White is not aiming for an advantage and prefers simple development, then the move ♟e2-e3 is quite understandable. Our plan does not change: we develop the kingside, add ♛d8-a5, and challenge White with our activity! We play ♝f8-g7!

  12. 6... Bg7
  13. 7. Nc3
    After 7. Nc3

    Let's pin the ♞c3 by moving the ♛d8 to a5, with a clear hint at increasing the pressure through ♞f6-e4!

  14. 7... Qa5
  15. After 8. Bd2Black to move.
    At the board8. Bd2
    After 8. Bd2

    Since there are no dangerous discovered attacks from ♞c3, we castle, chess enthusiasts!

  16. 8... O-O
  17. 9. Nf3
    After 9. Nf3

    We play ♝c8xa6, offering White to trade bishops, after which we play ♛a5xa6, preventing White from castling. A small trick!

  18. 9... Bxa6
  19. 10. Bxa6
    After 10. Bxa6

    We capture back with the queen — ♛a5xa6!

  20. 10... Qxa6
  21. 11. Qe2
    After 11. Qe2

    Exchanging ♛a6xe2 is not very advantageous, as we allow the white ♚ to approach the center in the endgame, where it will have little to worry about. We play ♟d7-d6, opening a development path for ♞b8.

  22. 11... d6
  23. After 12. Qxa6Black to move.
    At the board12. Qxa6
    After 12. Qxa6

    We recapture with the knight — ♞b8xa6, clearly aiming for ♞a6-b4 to put pressure on ♟d5

  24. 12... Nxa6
  25. 13. O-O
    After 13. O-O

    We bring the last piece into the game — ♜f8-b8!

  26. 13... Rfb8
  27. 14. Rab1
    After 14. Rab1

    Black’s position is excellent! Let’s add fuel to the fire — ♞a6-b4 with a fork on ♟a2 and ♟d5

  28. 14... Nb4
  29. 15. a3
    After 15. a3

    We recapture the pawn ♞b4xd5!

  30. 15... Nbxd5
  31. 16. Nxd5
    After 16. Nxd5

    We capture in return ♞f6xd5!

  32. 16... Nxd5
  33. 17. e4
    After 17. e4

    Where is the best retreat? ♞d5-f6 or ♞d5-b6? It is best to temporarily block the "b" file for ♜b8 by playing ♞d5-b6, aiming for ♞b6-c4/a4 with a triple attack on ♟b2!

  34. After 17... Nb6White to move.
    At the board17... Nb6
    After 17... Nb6

    Black's position is strategically winning! The white pawns on the queenside are falling one after another!

2. Demonstration of Key Ideas

  1. 1. d4
    After 1. d4

    We play ♞g8-f6, developing the kingside knight

  2. 1... Nf6
  3. 2. c4
    After 2. c4

    We undermine the center — ♟c7-c5, putting pressure on ♟d4. If White is interested in fighting for an advantage, they will have to play ♟d4-d5, advancing the pawn and gaining a territorial advantage.

  4. 2... c5
  5. 3. d5
    After 3. d5

    Provoking the pawn advance, we sacrifice a pawn — ♟b7–b5 with the idea of undermining the support beneath ♟d5. After that, the starting position of the Volga Gambit, or Benko Gambit, arises.

  6. 3... b5
  7. After 4. cxb5Black to move.
    At the board4. cxb5
    After 4. cxb5

    The wonders of the Benko Gambit don't end here! We play ♟a7–a6, offering White to capture another pawn with the idea of further developing the ♝ with tempo to a6, recapturing one of the sacrificed pawns!

  8. 4... a6
  9. 5. Nc3
    After 5. Nc3

    If White is not determined to act, they can support the ♟b5. In response, we exchange with ♟a6xb5, forcing the ♞c3 to occupy an awkward square, temporarily separating it from the ♟d5.

  10. 5... axb5
  11. 6. Nxb5
    After 6. Nxb5

    We gain a tempo by announcing a fork with ♛d8-a5, forcing the ♞b5 to return to its original square.

  12. 6... Qa5+
  13. 7. Nc3
    After 7. Nc3

    It is important to constantly remind ourselves: we have played a gambit, having managed to give up a pawn for the initiative. We must play firmly and aggressively, putting problems before our opponent! We play ♞f6-e4, increasing the pressure on ♞c3

  14. 7... Ne4
  15. After 8. Bd2Black to move.
    At the board8. Bd2
    After 8. Bd2

    In case of an interposition, we are happy to exchange — ♞e4xd2, gaining the advantage of the two bishops. It is important, by the way, to understand that once ♝d2 leaves the board, White will have no worthy opponent for our ♝f8.

  16. 8... Nxd2
  17. 9. Qxd2
    After 9. Qxd2

    The potential of our position is very promising. The ♝f8 alone, having come out onto the long diagonal, already compensates for the lack of an entire pawn. We play ♟g7-g6, focusing on development.

  18. 9... g6
  19. 10. e4
    After 10. e4

    Develop the bishop — ♝f8-g7, getting closer to castling

  20. 10... Bg7
  21. 11. Nf3
    After 11. Nf3

    We castle, dear chess enthusiasts!

  22. 11... O-O
  23. After 12. Bd3Black to move.
    At the board12. Bd3
    After 12. Bd3

    We play ♟d7-d6, creating a solid pawn chain and freeing the d7 square for the ♞b8, which can later jump to either flank.

  24. 12... d6
  25. 13. O-O
    After 13. O-O

    We develop with ♞b8-d7, postponing the decision about the fate of ♝c8 for one more move.

  26. 13... Nd7
  27. 14. Rfe1
    After 14. Rfe1

    The point is that the position is semi-closed, and it's difficult to use the ♝c8 to open up the game, so we play ♝c8 - a6, offering to exchange our passive bishop for White’s more active one.

  28. 14... Ba6
  29. 15. Bxa6
    After 15. Bxa6

    We capture the bishop in return — ♜a8xa6. For the pawn we sacrificed, we get: 1) a powerful ♝g7, tearing up the board along the diagonal; b) an excellent pawn structure without any weaknesses + prospects for play on the queenside: ♜f8-b8, ♟c5-c4 + ♞d7-c5-d3 with pressure on ♟b2.

  30. After 15... Rxa6White to move.
    At the board15... Rxa6
    After 15... Rxa6

    Black's position is very promising. The key is to play dynamically, looking for ways to pose problems for White on the queenside.
