This must have caught Shirov off-guard. While the databases will show two games from the late 90s by Kramnik with this move, the games in question are blitz.
6...Be7
7.e3
h6
[7...0-0
is the usual continuation here. Among top GMs, Dreev, for whatever reason, was targeted as black with this line several times in the last years, despite obtaining good results, and always chose 0-0.]
8.Bh4
b6
A novelty. 8...0-0 was almost universally chosen here.

13.Bg3!?
An interesting decision by the ex-world champion. The obvious move was to exchange bishops on e7, instead he actually gives up the bishop pair in exchange for the e4 knight. Kramnik is already looking at the e4 push that will ensue after the exchange, and his central play and pressure on c6. The added purpose behind Rc1 becomes clearer.

This weakens the queenside pawns, notably b6, and makes white's job easier. [A more resilient try was 19...Qc7

21...Qd8
The discovered threats against the queen were too many.
22.Qf3
Classic Kramnik using his pieces to keep the pressure without compromising his pawns. At this point Shirov was not only in trouble in the position, but his clock was down to the last minute and he was surviving only on the 30-second increment he received after each move.
22...Rc7

Hitting both b6 and g6 since the f7-pawn is now pinned.
24...Kg7?!
