How to beat a GM

The 16 years old IM Benjamin Glendura (HUN) showed us recently how to beat a great GM and former World Champion like Anand. It is no secret a strong knowledge of endgames gives you an advantage; is it enough though? Benjamin was put on the spot by Anand when the GM chose the King and pawns endgame instead of a Bishop versus Knight one to finish their game. He succeeded with flying colors! I find the resulting endgame very educational and inspirational. It gives us hope to beat stronger players and even GMs if we can master the endgames. Now you know the secret too; easy peasy, eh? :-)

Kc7 {The key position! Black could hold on if the f7- and b6- pawns together with their King could lock down and not move anymore. That means black needs enough tempo moves, as well as to stop the white pawns from challenging b6 and f7. There is no chance on the Queen side since white has minimum 4 possible pawn moves. On the King side both players have 5 possible pawn moves now, so probably these ones will cancel each other out.
