As a beginner, I have always liked it when special moves of chess - castling, en passant, and under promotion - appear in a solution. I am particularly fond of castling problems. The rule for castling in a problem is that it is assumed to be legal unless it can be proven illegal (for example the bK must have moved previously). Here are some of my favorites along with some of my recent experiments with the Fleck theme and castling.
On 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.
