Chess Problems: Longer half-pin problems

12/5/2012 – In his introductory article on the half-pin theme the problem expert David Friedgood focused solely on twomovers.

In this article he looks at a few of the possibilities that extended half-pin problems provide, with explanatory notes, and then presents two problems for our readers to solve. Here now are the solutions.

Tashkent R10: Mamedyarov and Morozevich lead in penultimate round

12/3/2012 – "Dutch GM Loek van Wely shows White how to bypass the Open Sicilian.

This material can be used profitably by players from an elementary level all the way up to low master." Review.
