Wonderful idea, Tim!
I summerized the lines as follows:
1) 21. Nd5 (Uri Blass) and black has 3 possible responses:
a) 21...exd5? 22. exd5 Qxc5 (22...bxa3 23. Ka2 only delays) 23.Qe3+! Kd8
24. Ne6+! fxe6 25. Qxc5 dxc5 26. dxe6 +-
b) 21...bxa3 22. Ka1 Qxc5 unclear (Dan Andersson)
c) 21...Qxc5 (Tim Mirabile; most convincing so far) and now
22. a4 as given by Uri Blass looks quite good for black after the
simple 22...Bxa4.
2) 21. axb4 dxc5 22. Nb3 (22. Nde2 transposes to Crafty - Fritz; Tim Mirabile)
c4 23. Bxc4 Qxc4 24. Rd4 Qc7 25. Rgd1 Bc6 26. Nd5! exd5 27. exd5 Bd7
as given by Dan Andersson. Black's king should be safe on the d-file
I love these complex tactics in the Najdorf ;-)
If anybody is interested i have gathered all analysis that was published here so
far and put it into a Chessbase 6 database. Simply send me an e-mail if you want
to have this analysis.

Alex
