Kibitzer's Corner
Mar-21-08  Knight13: 46. e5!! opens the e4 square for White's knight to fork on after Ng5+ if Black king ever decides to sneak in. It also serves a seconday purpose of shutting black's King out by using his own pawn.
Jun-08-16  zydeco: The extravagant opening by Smyslov is a sign that he was desperate at this point in the match.
