Feb-18-12  kia0708: I think he won the World Chess Solving Championship in 2012. Am I correct ?

Or was it John Nunn (England) ?

Sep-22-12  MarkThornton: Kacper won in 2011:

The 2012 event is taking place soon in Kobe, Japan. I don't know the precise date, it may have already taken place.

Sep-22-12  MarkThornton: Kacper is now a GM:
Sep-22-12  MarkThornton: MarkThornton: To be precise, he became a GM at solving chess problems in 2011: He then became a GM at playing the game in 2012. So, he has joined the rare group of double-GMs, before his 21st birthday! In fact, he may be the youngest ever double-GM!

Congrats, Kacper, on a fine achievement.
