GM Sosonko is from Troitsk, but it's GM Finegold who acts like Troitsky in this study-like game from his youth. Though only an FM at the time, Finegold spots a winning tactic, and heads into the endgame an exchange up. His technique wasn't refined yet, but fortunately he could calculate like a computer, leading to an instructive win that should be in an endgame manual. Ahhh, youth.
