NDDES 38051 TERMINAL 19307 DYNAMIC 4142 CAPTURE 11465 SALVAGE 3233 DUPLIC 2184 RECLAIM 1410 BRANCH 1005886 Commentary, 29 November 2009. The above listing was produced using ReadIris 7.0 on a scanned image (a TIFF file) from research notebook #31 (2004-58-33) period May 1983 - October 1983 There were many errors in the extracted text file and these were corrected by hand by comparison with the scanned image (the *.tif file). From the above listing we assume that EXPERIMENTAL mode means maxtree = 600 (workspace of 600 positions per move), search width (MAX_WIDTH) of 19 moves and search depth of up to 7-ply. In this game Awit was never losing. At move 13 Awit played f4 and the statistics of ".29=M104" mean, equal postion (=) in Middlegame (M) taking 104 seconds to search with a width of 19 moves (. 9) from which the move in position 2 of the list was selected (.29). The opponent replied with NE7 and the statistics of "#44 O194" means that Black is in the Late Opening phase (O), and took 194 seconds to make the move. NE7 was not examined by White (#), the search width was either 4 or 14 moves and NE7 was in position 14. Other Black moves not examined by Awit were, 18, 24 and 41, all indicated by the "#" in Black's statistics. Whenever Black makes a checking move, White has amuch restricted set of choices, as illustraded by White statistics of "12+M", "13$E", "14$L" and "16$L" at moves 23, 33, 38 and 44. The notation "+" means ahead and "$" means well ahead in position and material. Outcome Awit 1 Ostrich 0 in Round 1 of the 4th World Computer Chess Championship, New York 22-25 October 1983.
