The Zagoruiko theme is named after the great Belarus composer Leonid Zagoruiko. A Zagoruiko requires at least two Black defenses to be met by different mates across at least three phases. For example, a 3x2 (3 phases) and (2 defenses) Zagoruiko could have the pattern of set, virtual, and actual play as follows:
Set: 1...a 2.A 1...b 2.B 1.Try? 1...a 2.C 1...b 2.D 1...x! 1.Key! 1...a 2.E 1...b 2.F There are thousands of 3x2 Zagoruikos in existence, but fewer 3x3s, and even less 3x4s, 4x2s, etc.

Chess ProblemsOn the side I like to dabble in chess problem composition. I am mostly interested in two and three move direct mates. I hope to convey the beauty and logic of chess problems with this blog. In the entries are some of my favorite problems and my own problems. Before looking at the problems I suggest reading this introduction to the chess problem world by the British Chess Problem Society. Also, here is a list of terminology and themes. Here is a link to my problems on yacpdb. ARTICLES
