Commentary, 28 Sept 2009
The above listing was produced using ReadIris 7.0 on a scanned image (a TIFF
file) from research notebook #33 (2004-58-35) period 4 April 1986 - 15 June 1986
There were many errors in the extracted text file and these were corrected by
hand by comparison with the scanned image (the *.tif file).

The above game is interesting because of the errors at moves 21 and 24.  They
appear to show a fault in the iterative widening mechanism, which was quickly
corrected overnight to form version AP9.5 that was used for the remaining games
in the tournament.  It is doubtful if the true nature of the fault was found, 
since the apparently sacrificial move Qxe1 for Black is still not examined.

It would seem that, EXPERIMENTAL mode here uses 600 nodes of workspace, 
search depth of 7 or 9 ply and search width of up to 9 moves.  The first 3 
moves are Book, Early opening phase is until move 8 and late Opening to move 15.
Middlegame goes to move 25, followed by early Endgame to move 33 and finally 
Late endgame there after.

12 moves by Black were not examined (about 25% of the total played), for 
example moves 11, 12, 15, 19, 21 and 22.  Indeed all those marked with a '#'.  
Some may have been bad, perhaps move 12 by Black. The narrow search and 
iterative widening mechanisms did not work well here.  Even so, Awit was ahead 
until move 24, Pxf5, when it failed to examine the reply Qxe1.  The loss of a 
Rook was too much.
