00:00It's a mate, but we have to open the bishop, but if white plays f5, e5, if white plays e5, opening the bishop, then black plays f5, closing this diagonal and forcing the exchange of the queens.
00:16So what white should do? The answer is simple, interference, that's what Fisher did, rook f6, brilliant move, beautiful move, and if black takes, then after e5,
00:30we lost the rook, but mate is inevitable, and we'll remember, checkmate is the end of the game.
00:41So Benko didn't take the rook, let king g8, after e5, h6, and Fisher simply moved the knight.
00:50There's no need to hurry, and Benko resigned because the big material losses are inevitable,
00:58but more likely it will still mate. So the game was over. So beautiful. Rook f6, that's all we have to know about interference.
01:09And now after we learned how to use interference in a practical chess, at this sample of Fisher's brilliancy,
01:25let's look at endgames, its studies. No pieces left, the board is open, but still interference could be a very, very powerful tool.
01:34So we have a very simple endgame. White goes this way, so this pawn on e7, just one move away from promotion.
01:45But how we can get there? Because promoting the queen now doesn't work since our bishop is hanging,
01:51and then, just imagine, you make this mistake, and then rook takes his three, it's a skewer,
01:56and we just lose our queen and even lose the game.
