[Event "Man vs Machine"]

[Round "5"]
[White "Kasparov, Gary"]
[Black "Deep Junior"]
[Result "1/2-1/2"]

1. d4 Nf6 {This time the Junior team avoided the Semi Slav (Utzinger,K)} 2.c4 e6 
3. Nc3 Bb4 4. e3 O-O 5. Bd3 d5 6. cxd5 exd5 7. Nge2 Re8 8. O-O Bd6 9. a3 
{With this rarely played move, Kasparov throws Deep Junior out of book. White
can either win space by b2-b4 or go for a kingside attack by f2-f3, then e3-e4
and Qd1-e1-h4 (Utzinger,K)} 9... c6 {A positional sound reply. Deep Junior
protects its central pawn and avoids Nc3-b5. A more active alternative was 9...
c5 (Utzinger,K)} 10. Qc2 {(?!) In my opinion, 10.f3 was more precise. On the
other hand I cannot imagine that Kasparov had not thought about the coming
sacrifice. (Utzinger,K)} 10... Bxh2+ {Wow!! Deep Junior sacrifices his bishop. 
Can Kasparov hold this position? Or is this only one of those speculative moves
that are so typical for Deep Junior? We shall soon know for sure (Utzinger,K)}
11. Kxh2 Ng4+ 12. Kg3 Qg5 13. f4 Qh5 14. Bd2 Qh2+ 15. Kf3 Qh4 {A very difficult 
situation for Kasparov. He can play 16.Ng3 with a draw by perpetual check. Or he 
can try to go for a win with 16.g3 in the hope to escape with his king to e1 
(Utzinger,K)} 16. Bxh7+ {I had indeed not expected this. But this move in conjunction
with the following move leads to a draw by perpetual check. Just a great game of 
Deep Junior (Utzinger,K)} 16... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+ 19. Kf3 Nh2+ 
{Draw agreed} 1/2-1/2
