Operating Rybka as black, (after 16. Bc5) the following position was reached. I was Zanzibarred. 1-0:

r2q1rk1/pb5p/2p2bpn/2Bpp3/2B1NP2/5Q1P/PPP3P1/2KR3R b - - 0 16


Anybody have any ideas how to save this game for black? I have tried many variations, but there are major king safety issues and I can't find a way to give black a chance.  Is 16 ... Re8 a better move than Rybka's Re7?  I would appreciate any input. The pgn is listed below.

I have quite a few games played in this line although not at this long time-control ... I will see what I can find

Thanks. 16. Bc5 is a new move in my database.
Parent - - By BigBen (****) Date 2007-02-13 19:30
Hi,
   Nope the move is new to me as well ... I\The Comp play this line as white and my database I guess like yours gives 16.Nf6 (I have 3 games in that position) all were drawn ... 16.Bc5 may well prove fruitful in my endevours lol ... I will put my 4Ghz Quad on that position and see what I get :)

Regards

Look forward to seeing the results Bigben. It appears it as Bc5!! is a good move.  I've tried to play this position out with Rybka alone, as a centaur, etc etc.  There must be a way to to give black at least drawing chances.

Maybe 16...Lg7 works.

I just played some moves...
1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6 5. Nc3 Bg7 6. Be3 Nf6 7. Nxc6 bxc6 8.
e5 Ng8 9. f4 Nh6 10. Qf3 O-O 11. O-O-O d5 12. h3 f6 13. Bc4 Bb7 14. exf6 Bxf6
15. Ne4 e5 16. Bc5 Bg7 17. Nd6 Rb8 18. Nxb7 Rxb7 19. Rxd5 cxd5 20. Bxd5+ Rbf7
21. Bxf8 Kxf8 22. Bxf7 Nxf7 23. fxe5 Bxe5

just an idea, but looks interesting
