I can also understand his surprise that both Fritz and Junior made the correct move and Hiarcs, which is considered by many to be the strongest commercial program available, made such a terrible blunder. This doesn't surprise me so much because I have played against Hiarcs and have seen blunders befitting a patzer. Now, I am not saying it happens often or that other programs don't ever make a blunder, but it is the pedestal that Hiarcs is on which makes us expect better. I have played Hiarcs at 40/2 and seen it make horrible moves with and without using the tablebases before reaching a 4 or 5 piece endgame. It has gone from a clear advantage to overlooking a simple and easy to play move for even an intermediate chess player, and having to settle for a draw. I have seen it permit me to get passed pawns and go from plus scores to minus scores in the middlegame. I'm not picking on Hiarcs here for other programs make errors too. However, Hiarcs has been put way up high on a pedestal and it's quite shocking when one encounters numerous errors from such a top rated program.
