Practicing with (emulated) old chess computers that I used to love to play with during the '80s in the early '90s.
I inadvertently may have found the Achilles Heel of the Super Constellation. It failed to find the drawing line because this would have involved a perpetual check. Instead, it makes a move that looks dumb.
It is not clear if the computer is smart enough to check for repetition of the position in its tree search because on an 8-bit computer this check would be very costly and slow it down The computer would not normally search deep enough to see a three-fold repetition anyway. Most chess engines today consider any repetition of the position to be a draw.
The Super Constellation only sees the draw after it reaches an 11 ply search. Back when I was using programs like Fritz 4 and Fritz 5 to analyze my chess games, I thought that an 11 ply was pretty deep, maybe equal to a low ranked Grandmaster from what I read. Today Stockfish quickly reaches 30 ply, and I use 35 to 40 ply to analyze my openings.
