notyetagm: Here's another discovered deflection for you, <Kwesi>, that I just saw Mamedyarov play on ICC. He was White and up by a pawn in the following position:
click for larger viewBlack has just played 23 ...  g7. Note that the Black d8-rook would be loose (White d1-rook attacker, Black e6-knight defender) if the White d5-knight were not on the d-file. This looseness means that the defending Black e6-knight would defend only the d8-square if the White d5-knight moved off the d-file. <So Mamedyarov used his masking piece (White d5-knight) to take what the newly overworked defender (Black e6-knight) no longer defended (c7-square) and played 24  c7!.> The resulting tactical liquidation forced the remaining pieces off of the board, leaving White a healthy pawn ahead in a king and pawn ending. Fritz 7 gives best play as 24 ...  xd1 25 xe6+ f6!? 26 xd1 xe6. In the actual game Mamedyarov's opponent resigned after seeing 24 c7!. Here is the complete game score:
