The so-called 1st World Fischerandom Chess Championship is slowly going on, for now only through online knockouts, but pretty soon four aspiring Champions should materialise themselves in the form of men. 1. d4 d5 2. c4 dxc4 3. Nf3 Ng6 4. Qc3 c6 5. 0-0 Nf6 6. Qxc4 Bg4 7. Ng5 Nf4 8. Ng3 h6 9. N5e4. After 9. Nh7 Bxh7 10. Bxh7 Be6 Black would be even more comfortable. 9. ... Nxe4 10. Bxe4 Be6 11. Qc2 Qd7. Black finally prepares for castling. 12. Bxf4 Bxf4 13. Nh5 g5 14. Rad1 Qc7. Her Majesty wisely sets herself at an equidistance from White’s Rook on the d-file. 15. Nxf4 gxf4 16. d5 cxd5 17. Qb3 0-0 18. Bxd5 Bxd5 19. Rxd5 Rad8 20. Rf5. If 20. Rh5 at once, then 20. ... Rd6 could follow. 20. ... e6?! 20. ... Rd2 really came into consideration, in order to answer 21. Qh3 by 21. ... Qd6 22. Qg4+ Qg6 23. Qxf4 Rxe2 with a playable game. 21. Rh5 Kg7 22. Qh3 Rh8. After 22. ... Qc2 23. Rxh6 Qf5 24. Qh4 Rh8 25. Rxh8 Rxh8 26. Qe7± White’s extra Pawn in the heavy piece ending may well be the premise of further opportunity for a win. 23. Qg4+ Kf8. The only acceptable move. 24. Qh4 Kg7. If 24. ... Rd2 then 25. Qf6! winning a Pawn and retaining good winning chances.

25. e3! Rd2. 25. ... f5!? 26. exf4 Rd4 would seem a reasonable option, trying to keep White bottled and tied for as long as possible. 26. exf4 Rxb2?? A gross blunder, losing on the spot. 27. Qg3+ 1 : 0. For after 27. ... Kh7 28. Qg5! White forces mate next move, while 27. ... Kf6 28. Rxh6+! ends with a regicide too (28. ... Rxh6 29. Qg5 mate). Finally, if 27. ... Kf8 then 28. Qa3+ winning a Rook.
