notyetagm: 24 h5!! is one of my favorite tactical shots.
The Black f6-knight must <BREAK THE ALIGNEMENT> between the Black e5-queen and the Black h8-king, else ♗e3-d4 <PINS> and wins the Black queen, so it cannot also <DEFEND> the h5-square.
The Black g6-bishop must <BLOCK> the g-file of the White g3-queen, g1-rook battery, else White mates with ♕g3-g7#, so it too cannot also <DEFEND> the h5-square.
That leaves the Black e5-queen as a possible defender of h5. But 24 ... ♕xh5 allows White to seize the h-file with <TEMPO> with 25 ♖h1. Then 25 ... ♕f5 to <DEFEND> the Black g6-bishop runs into 25 ♘d4!, winning.
24 h5!! exploits the fact that although three Black pieces -appear- to <DEFEND> the h5-square (Black e5-queen, f6-knight, g6-bishop), none of them really do.
