I went shopping for a chess computer and found nothing in town. The selection on the USCF website is only one item. I found something on a commercial website and placed an order. Affordable stand-alone chess computers need to be available.
Stand-alone chess computers like the Novag were nowhere near the strength of the chess programs of that day. Also, a stand-alone computer would require the cost of the platform plus the cost of the programming. That would go against the requirement for affordable.
Additionally, the cost of computer chess software is incrementally much lower than the cost of a dedicated device, and affords a machine that can be much more than a chess computer.
Frankly, a phone with a good engine plays well today -
I think there was once a time (maybe about three decades ago) when the stand-alone chess computers were the strongest commercially available electronic chess opponents, but, of course, that was then, and this is now.
These days, it is perhaps not so important what is the strongest opponent because so many are strong enough for many purposes.
If chess.com is anything like FICS or ICS, you can [finger] for information. Not sure about chess.com, but I’d think there would be a way to find out information about various opponents.
I wonder how. I know that Computer3-HARD always falls for the same tricks against me. It’s like they are programmed to make the same move sequences every time, even if it loses!
I would even a GM would have a hard time beating Stockfish on an android phone. Using the latest hardware, the difficulty should be close to 2800 if not more. Even on my Samsung Galaxy S2, I’d think Stockfish would clock over 2700 ELO.
