Cool Troitsky study!
Alexey Troitsky (March 14,1866–August 1942) is considered the ‘father’ of the modern chess study. Hardly a stranger to my readers, as I have posted several times on this blog some of Troitsky’s work.
I recently came into possession of a 1937 first edition english translation of his studies up to that time (‘Collection of Chess Studies by A.A.Troitzky‘–Whitehead and Miller) and occasionally I thumb my way thru it (it is a great travel companion) and try my luck solving some of them. Troitsky is a master of the ‘quiet’ move…this makes finding the correct solution all the more frustrating.
Below is a study that I tried over coffee this morning. (I had promised myself that I would dedicate about an hour a day to analytic exercises in the run up to the Gibraltar tournament!) It has a long solution (16 or 17 moves long), but is not that difficult to find. You have to find how White wins. Good luck!
