I tested Rebel 9, Fritz 5.01, and Hiarcs 6 (Fritz module) with the Louguet Test II on my K6/233 (with 512k internal pipeline cache). Fritz 5 and Hiarcs 6 were tested with 12 Megs of hash in Win95 (please don't tell me that Fritz 5 needs 100 Megs to run ideally as I still think that's the stupidest thing I ever heard of) with Fritz's automatic test processing with a setting of 2 plies (meaning it tests for an extra ply to verify the program doesn't change it's mind) and Rebel 9 had 13 Megs of hash in DOS 7.00. Here are the results: LCT II Positions Rebel 9 Fritz 5 Hiarcs 6 Pos1 3 Secs. 17 Secs. 3 Secs. Pos2 0 Secs. 2 Secs. 1 Sec. Pos3 ---- ---- ---- Pos4 5 Secs. ---- 2 Secs. Pos5 ---- 2:08 min. 28 Secs.

It suffered a decrease in it's score in Pos7 as it found Nd1 but then changed it's mind to Kh1 only to return to Nd1 after 2:32 minutes. It had the best results in the endgame positions though it should be noted that it's correct choice of Kg4 in Fin9 wasn't due to an understanding of the position but rather to an obscure element in it's evaluation. Fritz 5 performed quite respectably in all areas though I was surprised to see it not find Cmb10 and Fin6. Hiarcs 6 was quite outstanding in the test suite being the only one to find Pos12 and Pos14. In tactics it showed incredibly smart algorithms, posting best times in no less than 6 of the positions, yet unusually poor in Cmb8 and Cmb10. In the endgame positions the big surprise was in it's failing to solve Fin4.
