Dreev – Cifuentes Wijk aan Zee 1995 White to play On 1 Ng5 Black defends with 1…Nf6. What else can White do?
The sacrifice 1 c5! bxc5 2 dxc5 Nxc5 (not 2 … Bxc5 3 Rxd7 and 4 Bxc5) is strong after 3 Qc2.
Black’s knight is threatened and cannot get back to defend the kingside because 3 … Nd7 4 Qd2 costs a piece.
After 3 … Na6 4 Ng5! g6 and 5 Qa4! White either gets a decisive attack (5 … Nb8 6 Qh4) or wins material (5 … Nb4 6 Rxd6! Qxd6 7 Ne4).

Vydeslaver – Psakhis Ramat Aviv 1998 Black to play Natural moves include 1 … Bc6 and 1 … a5/2 … b4. What else?
It’s an excellent time for 1… Rxc3! 2 bxc3 Bc6 since the e4-pawn is doomed (3 Qd3 Qa8 4 Bg5 Bxe4! 5 Bxe4? Nxe4 and Black wins in view of discovered check, 6 Bxe7 Nf2+ 7 Kg1 Nh3 mate).
The game went 3 Bg5 Nxe4 4 Bxe7 Qxe7 and 5 f6 Qb7! 6 fxg7 Rc8 7 Qg4 Nd2 8 Rf2 Bxg2+ 9 Rxg2 Rxc3 with more than enough compensation.

No, because after 1...e4! 2 dxe4 dxe4 3 Ng5 Black gets a fine initiative with the Spielmann idea, 3 … e3!. Then comes 4 fxe3 h6 5 Nge4 Ng4!.
Black would be winning after 6 Nf3? Qxd1+ 7 Kxd1 f5! (8 Nc3 Nf2+). The game turned in his favor after:
