Continuing analysis:

[B]17 Ng5 Nf5[/B]

Try: [B]18 Bb6[/B] (threatening 19 Bxc6+ Bxc6 20 Bxa5)
But 18 ... cxd3 leaves our e-pawn hanging, and 19 Bxc6+ Bxc6 20 Bxa5 Bxe5 doesn't look good for us.

Try: [B]18 d4[/B] (preserving pawns and the Ne4-f6 threat)
18 ... O-O 19 Bd2 (to preserve threats at g5-h5)
then if 19 ... f6 20 Nxe6
if 19 ... h6 20 Ne4

Try: [B]18 g4[/B]
18 ... Nxe3 19 Nxe3 O-O 20 d4 (preserving pawns and the Ne4-f6 threat) then what's good for Black here?

[B]17 d4[/B] may be best for us, but needs more analysis.

If [b]17 d4[/b] O-O 18 what?

If [b]17 d4[/b] Nf5 18 what?
