I'm pretty sure that it was provided to us by David Kittinger as a binary file and we did not look much at it. I took the liberty of doing a very unscientific experiment, and discovered that forcing the program to make a move 20 times from each of the above five positions for Black, I got the following results: First move after 1.e4 -- 1...e5 (13 times) -- 1...c5 (5 times) -- 1...c6 (1 time) -- 1...e6 (1 time) Second move after 1...c6 2.d4 -- 2...d5 (12 times) -- 2...g6 (4 times) -- 2...d6 (2 times) -- 2...Na6 (2 times) Third move after 2...d5 3.Nc3 -- 3...dxe4 (13 times) -- 3...b4 (4 times) -- 3...g6 (3 times) Fourth move after 3...dxe4 4.Nxe4 -- 4...Bf5 (11 times) -- 4...Nd7 (7 times) -- 4...e5 (1 time) -- 4...Nf6 (1 time) Fifth move after 4...Bf5 5.Ng3 -- 5...Bg6 (20 times) So, given these probabilities, I would be surprised if the program played this line more than once every twenty games. It would appear as though the likelihood would be more like once every 100 games. jm
