• Woodward’s Unusual Classical Dragon - The Monthly Dragon

  Chris Ward examines an uncommon Classical Dragon line from the game between Andy Woodward and 2600+ GM Vasif Durarbayli. The system resembles a Yugoslav Attack, but White develops the bishop to e2 instead of playing the typical f3, leading to different strategic and tactical possibilities. Chris highlights several critical moments and believes Black could have improved with Rxc3, although Woodward eventually took over the initiative and won an entertaining game. | Photo: John Upham

For us news of his passing came out of the blue, and it left us deeply saddened.

• Help us build the next ChessBase

  We're planning the next chapters of ChessBase and we want input from the people who actually use it, before we decide what to build first. Help us by taking part in a survey that asks how you work day to day: your setup and hardware, how you use engines and databases, and which parts of the interface help or get in your way. Filling out the survey takes around three minutes. If you fill it out we will send you a thank-you voucher gift.

• Shifts and mirrors in a chess problem

  A year ago problem composer Werner Keym issued a challenge: compose a study in which White is winning – but one that can be shifted and mirrored vertically and horizontally, with all vertically shifted and mirrored positions drawing, and all horizontally shifted and mirrored positions losing. Here is the elegant solution, which reminds us of the famous Babson task.

• How much faster are computers today?

  In the early 1980s, as a fledgling TV journalist, I did a report on the fastest computer in the world. The Cray-1 cost eight million dollars and could do 130 million floating point operations per second. That was enough to calculate the weather, but also to win two consecutive world computer chess championships. How much faster are today's supercomputers? Take a guess – you are definitely not going to get it right.
