2017-08-12 18:57:49floreatdunum1702Nice Reti 
2017-08-12 20:57:22grom431821Reti? The opening? Or what? 
2017-08-13 17:12:13slowness20141683The position is actually from a 1996 game Sveshnikov-Volzhin, which was a Ruy Lopez: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Ne7 6.Nxe5 Qd4 7.Qh5 g6 8.Nf3 Qxe4 9.Qa5 Bg4 10.Re1 Qd5 11.Qc3 Bxf3 12.Qxh8 Qg5 13.g3 Qh5 14.Qf6 O-O-O 15.d3, etc. 
2017-08-19 18:38:41floreatdunum1702Reti mate. Qd8# mating a king on c7. 
2017-08-19 18:41:53floreatdunum1702As in from Reti - Tartakower, 1910. 1. e4 c6 2. d4 d5 3. Nc3 de4 4. Ne4 Nf6 5. Qd3 e5 6. de5 Qa5 7. Bd2 Qe5 8. O-O-O Ne4 9. Qd8 Kd8 10. Bg5 Kc7 11. Bd8# 
2017-08-19 18:49:55floreatdunum1702One should point out that in the game reference kindly given by slowness2014, Black did not play the obvious blunder 15... Nf5, but 15... Bg7. The game ended in a draw by perpetual: 16. Qf7 Bd5 17. Qe7 Qf3 18. Kf1 Qg2 19. Ke2 Bf3 20. Kd2 Qf2 21. Re2 Bh6 22 
2017-08-19 18:50:01floreatdunum170216. Qf7 Bd5 17. Qe7 Qf3 18. Kf1 Qg2 19. Ke2 Bf3 20. Kd2 Qf2 21. Re2 Bh6 22. Kc3 Qd4 23. Kb3 Bd5 24. c4 Qd3 25. Nc3 Bc4 26. Ka4 Bb5 27. Kb3 Bc4 28. Ka4 Bb5 
2017-08-19 18:51:23floreatdunum1702Possibly Black might have won with 23... Bc1 
2017-08-19 23:00:04chessisajedrez1731Wow, @floreatdunum's Reti-Tartakover is only 11 moves long!? Anyway, there is an even more similar mate in another CTS problem. Everybody praises it.
