1/7/2026 – In the final sections of our Christmas Puzzle Week we brought you a variety of famous and less well-known puzzles. Among them a mate problem that solves itself – literally. And one that looks deceptively simple, but requires a very subtle strategy to find the win. In no less than 46 moves! Can computers solve it?

1/5/2026 – Did you solve the famous retractor by T.R. Dawson? You had to retract White's last move and then deliver a mate in two. And the solution? Take back the move h2-h4 and then play exactly the same move: 1.h2-h4! g4×h3 e.p. 2.B×g6#. Outrageous! Today we bring you a second instalment of solutions from our Christmas Puzzle Week. With retractors, reflectors, missing pieces and more. Hoping you like such out-of-the-box puzzles.

1/1/2026 – Did you enjoy our Christmas puzzles? They were computer-resistant, which meant you could not simply ask a chess engine to solve them for you. Today we bring you a first batch of solutions – and reveal for the first time the solution to the decades-old problem of a game starting 1.e4 and ending on move five with knight takes rook mate. The solutions to the remaining problems will appear shortly.

12/31/2025 – Take a look at this relatively simple position. Can you figure out how White can win? And how many moves it will require to overcome Black's most resolute defence? You won't believe it.

12/30/2025 – In August 2019 I spent a week in France, at the training camp I had organized (together with ChessBase India) for young Indian super talents. Former world champion Vladimir Kramnik did the chess training, while I pestered the kids with logic puzzles. Most did not involve chess, but some did. Here are a couple for you.

12/29/2025 – In rotary problems the board is rotated by 180° for a second position with a different solution. It is usually pawns that make a different when you turn the board around. Or the king/queen positions, or castling is involved. Can one devise problems where these factors do not play a role? Yes one can, as our expert for out-of-the-box problems, Werner Keym, proves.

12/28/2025 – These days it is not easy to challenge anyone with problems or studies. Loading the PGN and clicking Start will usually get you the solution in seconds. So we are trying to provide you with "computer resistant" puzzles in this year's Christmas Puzzle Week. Today the subject is taking back a move in a given position and looking for a move to fulfil the condition. As in this 100-year-old problem by Thomas Dawson: it requires you to take back one move and then mate the opponent in two. Can you think how?

12/27/2025 – There are chess puzzles which only consist of a line of text, asking you to construct a position or a game that it describes. Some can be awesomely difficult, like the puzzle we first posted 41 years ago. Two world champions were not able to solve it. We tell you about that, and present a new ones, not quite as tough, for you to solve.

12/26/2025 – Take a look at this position, in which White should mate in two. Looks very easy, and hundreds of readers of the newspaper in which it appeared submitted a solution. But it was not correct. In our Christmas Puzzle week the consummate expert of unusual chess problems, Werner Keym, asks you to look carefully at the position and find a genuine way for White to mate Black in two moves. There are two other problems to solve.

12/25/2025 – Christmas day is usually celebrated with a Christmas tree – in problem chess circles occasionally with a puzzle shaped like a Christmas tree. Like this example, composed by the famous Thomas Rayner Dawson, 101 years ago. It illustrates the universal principle of symmetry, and how it can be broken in a chess problem. Mathematics professor Christian Hesse delves into the very profound thinking behind the problem. But you are invited to solve it first.

8/15/2025 – In his youth, Jason Kouchak had two great idols: lyricist Don Black and designer and game inventor Ernö Rubik. He later had the opportunity to meet both of them in person, and all three share a love of chess. Kouchak's two heroes from his youth are now over 80 years old, but they draw a great deal of inspiration and strength from their involvement with chess.

How it came about is explained by ChessBase Magazine author GM Dorian Rogozenco in this video reconstruction.

Tina Popli writes about Ashwath’s remarkable feat and his journey so far. | Photo: David Llada
