Kashdan vs Alekhine 1933, Black to Move
No great chess player complicates matters unless they find a simple solution. Alekhine was not an exception, White’s last move was Nb5 attacking the c7 pawn. Alekhine used little tactics to reach an endgame where his knight and passed pawn on the g-file are simply enough to win the game.
Here is the solution and the rest of the game.
