Mar-04-21 M Lomineishvili vs A Gara, 2004   Delboy: I believe black missed a forced mating sequence on move 33. 33. ... Rxf2+ 34. Kxf2 Qd2+ 35. Kf1 (35. Kxf3 Rf7+ 36. Qf6+ Rxf6#) Qxc1+ 36. Ke/f/g2 Qd2+ 37. Kf1 Qe1+ 38. Kg2 Qe2+ and 39. ... Qh2/f1#. Maybe she was in time trouble      Mar-03-21 Rajkovic vs Matulovic, 1976   Delboy: 18. Kxf2 Rf8+ 19. Kg2 Rxf1 20. Kxf1 Qxg3 and white cannot stop mate on f2. Other lines do not seem to fare much better      Mar-02-21 V Makogonov vs Kolobov, 1927   Delboy: 29. Qxh7+! An unusual, but very effective, way to win a piece and the game. A future Tuesday puzzle?      Feb-27-21 Chiburdanidze vs Goldin, 1989    Delboy: Very nice winning combination beginning with 29. ... Ra4. Black had to already see the not-too-obvious follow-up blows 33. ... Nd3 and 35. ... Rxh1. A Friday puzzle?      Feb-26-21 Y Porat vs Gligoric, 1965   Delboy: Another subtle precondition to the soundness of Gligoric's knight sacrifice is that 19. Qd3 (or 19. Qd4) does not work because of 19. ... Qh2+ 20. Kf1 Bh3 (20. gxh3 g2+ 21. Kf2 g1=Q#). With the queen still on d2, g2 can be defended by now moving 21. Bd3      Feb-23-21 Pachman vs I Balanel, 1956   Delboy: What a swindle. Had white played 35. Kh3 then black could have resigned gracefully. Admittedly the quite spectacular 35. Bh3 Ng4+! is not that easy to spot, even though it forces mate in 3      Feb-20-21 V Sokolov vs V Tomovic, 1960    Delboy: After move 19 the three pawns at e4, f3 and g2 look harmless, but look how they create absolute havoc in the next 13 moves      Feb-20-21 J Vanheste vs L Riemersma, 1987   Delboy: Nice attack, especially the crushing follow-up sac 22. ... Rf2. The rook cannot be captured due to 23. Kxf2 Qh4+ 24. Kf3 (24. Kg1 Qg3+ and Qg2#) Qxg4+ 25. Kf2 Qg2+ 26. Ke1 Qg3#      Feb-15-21 R Lau vs M Thesing, 1996   Delboy: The rook sacrifice 25. Rxh6+ rips open the defences around the black king and succeeds because of the offside placing of the black queen, which cannot react to the quiet but deadly 27. Qe7. Note how 27. ... Bg6 28. Rxg6 Rg8 fails to a second rook sac on h6: 29. Rxh6+ Bxh6 30. Nf7+ ...      Feb-15-21 M Homuth vs A Nickel, 1988    Delboy: Quite an amazing sequence starting with 17. Qb7+. The move probably achieves nothing without the follow-up rook sac 19. Rxa7. Thereafter black just cannot seem to deal with white's advanced pawn, with his pieces getting in each other's way. Worth a GOTD or a weekend puzzle?
