Lev D. Zilbermints( 1999) Ernest Colding( 2234) Westfield G / 30, June 10, 2007, ECO D00 Blackmar-Diemer Gambit – Euwe Defense 1. d4 Nf6 2. f3 d5 3. e4 dxe4 4. Nc3 exf3 5. Nxf3 e6 constitutes the Euwe Defense. It was recommended in the 1950’ s by former World Champion Dr. Max Euwe, after whom it is named. 6. Bg5 Be7 7. Bd3 Nbd7 8.0-0 c5 The last move is not that common. Out of over 2 million games, I could only find 17 games with it in the German www. chesslive. de online computer database. 9. dxc5 Here, other moves are possible:
a) 9. Qe1 a6 10. d5!? exd5 11. Nh4 c4 12. Nf5 cxd3 13. Nxd5 0-0 14. Nfxe7 + Kh8 15. Bxf6 Nxf6 16. Rxf6! Be6 17. Qh4 Bxd5 18. Rh6! Be4 19. Rh5 Qd4 + 20. Kh1 Qxb2 21. Rf1 Bxg2 + 22. Kxg2 Qxc2 + 23. Kh1 d2 24. Rd5 Rae8 25. Qb4 a5 26. Qh4 Qc1 27. Qxh7 +!! Kxh7 28. Rh5 +! Black Resigns

b) 9. d5 Nxd5 10. Nxd5 Bg5?? 11. Nxg5! exd5 12. Nxf7 Qb6 13. Qe1 + 1-0, Stefan Nussbaum – Frank Entz, Bernkastel – Kues SJR – ch U20, 1996.
9 … Nxc5 10. Bb5 + Bd7 Here the database gives only three games with this move order. White emerged the victor in one game while Black won the two remaining games. Mind you, in one game White resigned prematurely! 11. Qe2 a6 This move is not in the database. Previously seen was 11 … Qb6, as in Ertel – G. Schuh, correspondence 1998.
That game continued 12. Be3 Bxb5 13. Nxb5 a6 14. Nbd4 0-0 15. c3 Nd5 16. Bf2 Bd6 17. Rad1 Qc7 18. c4 Nf4 19. Qc2 Ng6 20. b4 Nd7 21. c5 Bf4 22. Ne2 Nde5 23. Nxe5 Bxe5 24. Bg3 b6 and White prematurely resigned.
Sure, he is a pawn down, but so what? He could still fight on and draw the game. Personally, I have fought back from worse odds and prevailed! Though it must be said that my games were over-the-board, not postal!
There was this case, eleven years ago, when International Master Angelo Young got cocky trying to win the game and stalemated me! He had two Queens, a Knight, a Rook, four pawns, and another one about to Queen. I had a lone King with nowhere to move. And, oh yeah, the opening was a Blackmar-Diemer Gambit! I will publish that game next time.
12. Bxd7 + Ncxd7 13. Rad1 Qb6 + 14. Kh1 Qxb2 Uh-oh! This pawn grab must be similar to the Sicilian Defense: Poisoned Pawn Variation! 15. Rd3 I had thought about all kinds of tactics involving sacrifices on f6 and d7, but everything is too well defended. Thus the text move is played. 15 … Nc5 16. Rb1 Nxd3?

Really, I have no idea why Colding played this move, giving up the Queen for two Rooks. Perhaps, as the flow of the game showed, he did not analyze deep enough. Me, I calculated that after 16 … Qa3 17. Re3 Qa5 18. Bf6 gxf6 19. Ne5 Black has real problems with development. Admittedly, I analyzed only part of the above-cited variation; the rest was found during the typing of this article.
17. Rxb2 Nxb2 18. Bc1
Here I offered a draw, concerned about my opponent’ s seeming compensation. Colding replied,“ You are asking me for a draw? Draw declined.” I took a look at the position, saw that I could win a free piece, and answered,“ Okay, have it your way!” 18 … Ba3 19. Nb1! This was the move that Colding missed. … Rd8 Trying for a cheapo on d1. 20. Nfd2 0-0 21. Nxa3 Na4 22. Qf3 Nd5 23. Nac4 b5 24. Ba3 bxc3? Here 24 … Rfd8 was best. Now White gets a decisive advantage. 25. Bxf8 Kxf8 26. Qa3 + Ne7 27. h4 c3 28. Ne4 Rd4 29. Nxc3 Rxh4 + 30. Kg1 Nb6 31. Qd6! f6 32. Qxb6 Rc4 33. Qb3 Rc6 34. Ne2 Kf7 35. c4 Rc5 36. Qb6 Rc4 37.

After saying“ I resign”, my opponent tore up his scoresheet.
