Subject: Incredible novelty by Pro Deo: analysis wanted!

The following game was played in the 6th round of the Dutch Open:

[Event "24th DOCC"]
[Site "Leiden Ned"]
[Date "2004.10.17"]
[Round "6"]
[White "Pro Deo"]
[Black "ANT"]
[Result "1-0"]
[ECO "C42"]
[PlyCount "77"]
[EventDate "2004.??.??"]

1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. d4 d5 6. Bd3 Be7 7. O-O Nc6 8. c4
Nb4 9. Be2 O-O 10. Nc3 Bf5 11. a3 Nxc3 12. bxc3 Nc6 13. Re1 Re8 14. cxd5 Qxd5
15. Bf4 Rac8 16. h3 Be4

All well known, in the match Leko-Kramnik this was played twice. Leko didn't
manage to create even a slight edge and switched to 1.d4. Now Pro Deo thought
for some minutes and responded with an incredible move:

17. Nd2!!??

Just letting black take on g2!! During the game we couldn't believe this is
correct, but some analysis yesterday revealed that maybe this is a very
interesting idea! Don't forget that as a Petroff player you want a quiet and
nice draw, now you are drawn into a pool of crazy complications. As withdrawing
the bishop is tantamount to saying that 16 ... Be4 is wrong, there is only one
critical move to consider:

17 ... Bxg2. White responds with 18. Bg4!, threatening the c8 rook and also 19.
f3! winning the bishop.

Two replies are posssible:

A) 18... Bh1!? 19. f3. This looks good for White, but additional analysis is
needed.

B) 18... f5 (played by ANT and looks most logical) 19. Be2! (threatening Bc4)
and again White seems to have very interesting tactical chances. At least after
an hour of thinking my engines indicate a White advantage.

So what is the truth here!? Is 17. Nd2!? a brilliant novelty, or just a typical
tactical machine move creating interesting chances?

Please post your analysis!
