It sounds like you should just buy the latest Fritz and use that. I can't correlate your stated prices with Fritz versions. I recommend the current version, Fritz 14. The engine isn't the strongest, but it's plenty strong enough. You can add Stockfish (free) if you want more strength. Forget about Rybka.
There are other, free alternatives, but I'm assuming you want a simple solution. With Fritz you'll get a good interface, a strong engine, an openings book and a database. It's a pretty good package and you can add as many UCI engines as you want.
Hello my chess friends, I am in need of advice on buying a chess software. I do have chess arena and it does come with about ten engines that are 5+ years old. But my problem isn't even the engines but the Arena software itself. It doesn't always work, or is confusing. I wouldn't mind getting something with 3d chess board models like Fritz 13 and 14 but I am not sure whether I should get the $39.99 version of Fritz or the $70 version which supposedly thinks better.
I looked over the Rybka site and I am confused about it as well. Do they just sell the engine and you are supposed to find your own software to run it? Or does it come with full featured software in which to analyze games?
If you have other suggestions please let me know.
Thanks in advance!
