Azerbaijani Grandmaster Mamedyarov painted today a minimalist masterpiece, actually doing what he did not succeed in doing in his game against 丁立人 (Dīng Lìrén) just two days ago. So, yes, even a King with all of the mighty power of two Queens is susceptible to be mated! 34. e5 Nxb5?? Grischuk didn’t obviously suspect how much deadly this Pawn is. 34. ... Nf5 (35. Be4 e6) would have kept the balance. 35. e6!! And here is the brilliant touch! Grischuk had probably calculated only 35. Bxb5? c2 36. e6 c1=Q 37. Qxc1 Qxb5 38. exf7 Qd5+ with a draw coming soonly. 35. ... Qa3. Or 35. ... fxe6 36. Qxe7+ Kh6 37. Qf8+ Kh7 38. Qf7+ Kh8 39. Qf6+ Kh7 40. Be4 and finis. 36. Qxb5 c2 37. exf7 Kg7 38. Be4 c1=Q 39. Qe8 1 : 0. For if 39. ... e6 then 40. f8=Q+ Qxf8 41. Qxg6+ Kh8 42. Qh7 mate.
