The first 14 moves were book moves and Junior did not calculate for a second to
find them.

The first computer move was 15.exd4 and Junior was happy with it(+0.18)

I do not think that this move was the error and Junior could do a draw later in
the game.

15.Bc6 Bxc6 Nd4 is also possible and seems to me better but I cannot see 1147
knodes per second so I may miss something.
