Checks on the wK are always of interest in a two mover. Recently I have been exploring an idea that changes a set capture reply to a check by exploiting a self-pin. Specifically, there is a battery aimed at the bK with the front piece pinned. In the set play the capture of the front piece checks the wK and is countered by a capture by the rear piece of the battery. The key will make some type of error that abandons this reply but now White exploits the fact that Black self-pins when it checks. This idea can lead to some fantastic keys. Please also see my arcitle in the September 2016 Problemist Supplement. We begin with a classic by Mansfield.
Finally we end with some of my problems that have been published but whose solutions are not yet available. Happy solving!
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.
