Oh yeah, manufacturers routinely overestimate the ratings of their chess computers. (Can you say "marketing"?) I always mentally subtract 150 to 300 ratings points from any advertised chess computer rating. There are some independent rating lists of dedicated chess computers that are reasonably accurate. Never take a manufacturer's rating as gospel.
Amen. This is what I was saying. Excalibur had me thinking I had broken 1800, and since I studied Lev Alburt's course fully at the time (taking four months out of my life and studying every day) I thought Excalibur may be right. However, I soon found Lev Alburt says that course I took (the first two volumes) takes you to 1600+, not 1800+. Is it so strange that before all my timeouts, I broke 1600+??? Lev Alburt would know. Alburt says 1600+ and I broke 1600+ on redhotpawn, not using any books or computers, or programs... nothing... but casually moving, hardly ever taking any time to think. Sometimes, playing like blitz even. However, I do think I could have broke 1700 if I had taken a long time on my moves on redhotpawn. But, anyway, I believe those e-chess Excalibur chess computers in radioshack are rated around 1500 ELO. I beat it every time on the highest level, level 72, using King's Gambit, Scotch Game, etc... Keep in mind, this is with the white pieces all the time. So, let's say with the White, I'm 1600+ and e-chess is around 1500. So, yeah, you're correct. Chess computer manufactures overestimate their chess computer's rating for the sake of sales. The e-chess - on the box - is suppose to have an estimated rating of 1700. I will agree, that once in awhile, e-chess plays a strong 1700 tactical game, and ususally I was drawing at that point in the endgames mostly. But, mostly, if you play positionally against e-chess and truly think through the variations, you can crush e-chess if you break 1600+ with Lev Alburt's Comprehensive Chess Course VOlumes 1 and 2. My only lifetime chess goal is to reach 1800 USCF. That's my true goal.
A side note, if you want a strong computer for a class player, I suggest Mephisto Chess Explorer endorsed my Kasparov. I never beat it in a single game on the highest level. It is a power algorithm, a monster in my opinion for any class player. I put my Mephisto against Chessmaster 9000's Jade (rated slightly above 2200 as I remember), and Mephisto crushed her!
Oh, another interesting side note, I played the 1800 Josh on Chessmaster 9000 a few times, and a few other 1800 personalities, and usually drew them. This tells me that my accurate prediction of rating strength is right around 1600. Chessmaster 9000 ratings are inflated about 200/300 points. I believe around 250 points of inflation from my experiences. And, if you look at my graph, you can see the 1600 heights I achieved with Lev Alburt's course in Newport, Oregon when I was studying an hour every day and playing one serious game a day. I think anyone who wishes obtain a 1600 strength, should definitely invest in the first two volumes of his course. At the least, if you dedicate your life for a time to those two volumes, you will be a strong little 1500. Just some advice for people wanting get into the 30% of chess players.
