bxa4 Rxa4?! {This barely favors White, whereas 27... bxa4 barely favors Black.  Even the infinite level makes the wrong move here.} 28. Rxb5 Raa2 29. Rf5 g6 30. Rf4 Kg7 31. g3 g5 32. Rf3 g4 33. Rf4 {Diagram.} Kg6?? {The game was technically a draw up to this point.  At first, it is hard to understand how the computer could drop a pawn when it is looking 4 plies ahead.  The computer is afraid of 33... h5 34. Rc7, but Black draws by playing both rooks to the first rank with a mate threat.   Then White has to go for a perpetual check with Rcxf7+.  Even the infinite level takes 12 hours to see the draw with a 10 ply search after 33... h5 34. Rc7.  To see that 33... h5 draws takes around 80 hours where the computer only reaches an 11 ply search depth!} 34. Rxg4+ Kh7 35. Rf4 Ra7 36. Rc6 Rb7 37. Rh4 Kg7 38. Rhxh6 Rbb2 39. Rhf6 Re2 40.

Kf5 Rh1 49. e4 Rh3 50. e5 Rd3 51. h5 Rh3 52. h6+ Kf8 53. e6 Rh1 54. g6 {I thought that this was me trying to get too fancy, but Stockfish doesn't have a problem with it.} fxg6+ 55. Kxg6+ Ke7 56. Rf5 Kxe6 57. Rh5 Rg1+ 58. Rg5 Rd1 59. h7 Rd8 60. Kg7 Rd7+ 61. Kh6 Rxh7+ 62. Kxh7 Kf7 1-0

The Super Constellation fails at deep calculation.  It sees shallow tactics very well, which is where its strength comes from, so it appears to be pretty strong at speed chess.  It is not clear if the computer can calculate three-fold repetition or any repetition on a deep search because the 8-bit hardware limitations would make this check very inefficient.  This might be the reason the computer fails in the above position.  The computer would not normally search deep enough to see a three-fold repetition anyway.

Other than missing the draw, the Super Constellation played a very solid game.  According to Stockfish, I made no mistakes in this game.  This is what it takes because the computer will punish small errors.
