Here is a brilliant chess puzzle composed by Soviet chess composer Vitaly Chekhover where white forms a fortress and manages to draw the game! Black’s extra queen turns out to be useless in a battle against White bishop! In the end I am testing Stockfish 10 but as expected the engine misevaluates the position and the reason is that still engines are unable to understand fortresses!
