Can't touch this! (An Alekhine annotated gem).
How do you defend against three possible checkmates coming from an opponent who offers you a Queen and leaves her "unprotected" for 4 moves? The problem is... you can't touch her (the Queen)! According to Alekhine, Black makes an inaccurate 5th move... but the loss comes when he slips again 7 moves later. It is just a beautiful game. Enjoy the game and Alekhine's annotation!
