Viswanathan Anand 2715 Boris Gelfand 2685 Linares 1994 Black to move
The position is extremely sharp, and both kings feel unsafe. In such positions, the cost of an error is very great, and even the greatest players cannot always find the decisive continuation. Finding the winning path for Black requires colossal effort. One idea that is obvious is pinning the Ng3 with the bishop coming to h4, whilst it is also tempting to eliminate the Nc4, since the rook on a5 is hanging, and there is an unpleasant check at d6. However, all Black’s efforts are dealt with by the queen, which occupies a great defensive position on e3 – it pins the Be6 and indirectly defends the Ng3, and is ready at the necessary moment to close the b8-h2 diagonal with the move f3-f4. The key to winning is to shift the queen from its ideal position, before making a decisive attack on the white pieces:
28...Bg5!!
In the game, there occurred 28...Rxc4 29.bxc4 Bh4 30.Kf2 Qxc4 (on 30...Rg5, there follows 31.f4 – this is where we see the excellent position of the queen at e3!) 31.Qd4 Qxc2+ 32.Rd2 Qc5 – the endgame looks equal and ended in a draw.
29.Qd3
Black wins easily after 29.Qe2 Rxc4 30.bxc4 Bh4 31.Kf2 Rg5 – there is not the move f3-f4, and the Ng3 is simply lost.
29...Rd5 30.Qe2 Rxd1+ 31.Qxd1
Taking with the king allows the black queen to be included in the attack with tempo: 31.Kxd1 Qd8+ 32.Ke1 Qd4 33.Rg2 Bf4 34.Nf1 Rh1 – Black completely dominates, and has the irresistible threat of 35...Kf8, followed by 36...Bh3.
31...Rh2 32.Qd4 Bh4 33.f4 Qc6!
With the irresistible threat of 34...Qf3.

Black to move
In this case, the zwischenzug helps Black equalise.
A) 13...cxd5?! 14.Bxg7 Kxg7 15.bxc4+=
B) 13...Qd6?! 14.Bxg7 Kxg7 15.bxc4+=
14.Bxc3 Bxc3 15.Qxc3 cxd5
Black even temporarily wins a pawn.
16.Qc7 Nd7 17.Bxd5 Qxd5 18.Rad1 Qe6 19.Rxd7
Draw, because the variation 19...Qxe2 20.Rxe7 Qxa2 21.Qxb7 Rab8 22.Qxa7 Qxa7 23.Rxa7 Rxb3, leads to a complete elimination of the fighting forces.

White to move
17.Rd1!
It turns out that we can first attack the queen, creating in the process the deadly threat 18.Qxc4+. In the game, there followed 17.Qxf5 Qd5 18.Qf3 Qxf3 19.Nxf3 Bf6, with Black having sufficient compensation for the pawn. After:
17...Bd5 18.Qxf5
