Chess Puzzle of the Week (120): Solution

Last week’s puzzle: Yang-Fan Zhou crashed through against Sjef Rijnaarts (Amsterdam 2013) by means of a queen sacrifice to draw the black king into a mating net created by two rooks and a knight:

26. Qxe6! fxe6 27. Rxf8+ Kg7 28. R1f7+ Kh6 29. Rh8 g5 (or 29… Qd2 30. Rhxh7+ Kg5 31. h4+ Kg4 32. Rf3 threatening Rg3#) 30. Rhxh7+ Kg6 31. Rhg7+ (A slightly quicker finish was 31. Rfg7+ Kf6 32. Nf2) 31… Kh6 32. Nf2 Rb8 33. Ng4+ Kh5 34. Rh7+ Kg6 35. Rfg7#

My review of A Modern Guide to Checkmating Patterns by Vladimir Barsky has now been published.

Here’s another example from this book, starring former Richmond Junior star Yang-Fan Zhou, playing the white pieces here against Sjef Rijnaarts (Amsterdam 2013). How did he use his knowledge of checkmating patterns learnt at RJCC to score a quick victory here?

Chess Puzzle of the Week (119): Solution

Last week I left you with this Mate in 2 by Alberto Mari.

This problem exemplifies the Mansfield Couplet, named after the great English composer Comins Mansfield. “Two black units control a white battery. In two variations, each loses control by self-pin. White’s battery mate eliminates the other black unit’s control.”

The solution is 1. Bf7 (threatening 2. Ne3#), which, while setting up a battery against the black king, leaves the rook on b6 pinned. The thematic variations are 1… Kc5 2. Nxb4#, with the e7 pawn now pinned, and 1… Kb3 2. Nxe7#, with the b4 knight now pinned. We also have 1… e6 2. Rb4#, 1… Nxd5 2. Qc1# and 1…Rxb6+ 2. Nxb6#. There’s also a changed mate: in the diagram 1… Kb3 would be met by 2. Rxb4#. The try 1. Qa3 is refuted by 1… e5.

I hope you enjoyed this: well done if you managed to solve it!

In the game Rogelio Antonio Jnr – Dao Thien Hai (Kuala Lumpur 2005) White concluded with 19. Qxg7+!! Kxg7 20. Nd5 and Black resigned, “since after 20… exd5 21. Nf5+ Kg8 22. Nh6# is mate, whilst after 20… e5 21 Nxc7 exd4 22. Bxd4 White wins the exchange, obtaining an absolutely winning position.”

The game Kulaots – Antonsen (Borup 2010) concluded 21. Rxa7!! Rxa7 22. Bg5!, winning either king or queen because Qxg5 would be met by Nxf7+. Themes: deflection (twice), decoy, trapping a piece, knight fork, back rank mate.
