Following excerpt is from IM Larry Kaufman's review of Hiarcs 7 "HIARCS, by Applied Computer Concepts Ltd. with chess engine by British programmer Mark Uniacke, has been one of the very strongest programs for the last several years. The current version, 7.0, is apparently no exception. The latest Swedish rating list (the most widely accepted standard for comparing computer programs) ranks it third, just an insignificant 9 rating points behind the co-leaders (CM 6000 and Fritz 5.32) and substantially ahead of the latest rated versions of such strong programs as Junior, Rebel, MChess Pro, and Genius. Moreover it is up an impressive 43 points from its predecessor, Hiarcs 6. To fully appreciate just how strong Hiarcs 7 is, consider that its Swedish rating of 2567 was earned on hardware (200 MHz MMX) markedly inferior to the latest models (450-500 MHz). Moreover, the Swedish ratings are particularly severe, almost certainly more conservative than FIDE ratings and far below USCF ratings. These ratings are based on 40/2 games with other computers, with the overall level of the list based on games with human competition some years ago. Although I suspect that the level of the top computers may be a bit overstated now due to failure to recalibrate the list based on today's GM level computers, this should be offset by the severity of Swedish ratings in the past, so my guess is that the 2567 rating at 200 MHz would hold up in FIDE competition today, which would imply a FIDE rating over 2600 on today's fast machines. In other words, HIARCS 7 plays tournament chess on a par with the top five players in the U.S. This in turn implies that at action chess (game/30') HIARCS 7 probably plays around 2700 FIDE level, on a par with the number ten player in the world, and should play blitz better than Kasparov, Kramnik, and Anand."
