Chessmaster personalities

You are obviously wizard.

And you are obviously being sarcastic, but I am telling the truth.

It will depend on the hardware that the engine is running on. If it's on a mobile device, it will be a lot weaker. But in 2002, Chessmaster beat Larry Christiansen 2-1/2 games out of 4. Larry was probably over 2500 in rating. I'm guessing that the Leko personality will be a little weaker than the Chessmaster personality, but probably not by much.

Taking twice as much time than the engine probably gives you a +50 or +60 point rating  advantage over using the same amount of time.

Thanks for your reply. I ran the whole game through an app called analyze your games which calculates performance rating per game. It uses Stockfish as a reference point, and it turned out that "Leko's" perforomrance wa around 2300. Its a funny app, btw. The game was played on my laptop from 2012. It's nothing special, but it is still a decent machine. 2.3 Ghz single core processor, 1 Gb RAM.

Alekhine does tend to play weird form tme to time. It may have to do something with settings or my laptop is simply too slow.

well played! I am even struggling to play against Vanessa there (2000-ish personality)

Maurice Ashley is really good. A lot of smooth games.

 Well, I was curious to see how Vanessa would play, and after 11 moves I was having +1.2 centipawns advantage according to Stockfish. This is how the game went: 

So even though I didn't play the very best moves throughout the opening, I still had +1.2 centipawns advantage after only 11 moves so I really begin to wonder what the heck is going on.

I guess you're right.

Congratulations!! You are really exceptionally talented guy. 1:1,000,000 people can beat the Grandmasters. Dont argue with another 999,999 noobs here, they wont believe you. Find the nearest and highest rated world chess open tournaments. You should be the Candidate for 2020 world chess championship.

Good luck bro.

Grow up.

See , noobs start arguing!

 I'm an expert in smositional chess.

I ran a couple of quickie tournaments: Chessmaster 10 vs. Leko, and Chessmaster 10 vs. Alekhine. Both the Leko and Alekhine personalities seem to be roughly -175 elo compared to the Chessmaster personality.

I modified the Chessmaster personality to not ponder (that is, not to think on opponent's time), and changed the hash size from 16 MB to 128 MB, to match the CCRL testing conditions. (I did not change the settings for Leko or Alekhine.) The CCRL 40/4 tests rate Chessmaster 10 at 2616 elo.

So, if you believe that the CCRL ratings are close to true, then the Leko and Alekhine personalities should be performing at a little over 2400 elo.

Caveats: Admittedly, the two tournaments were with a very small number of games, so the strengths of Leko and Alekhine are very rough approximations. Also, since all three of these personalities have zero randomness, there will be some identical duplicate games.

I strongly doubt that Leko is +2400. This is the game I drew against him.:

I had strong initiative throughout the middlegame, and I was up the exchange in the endgame but he eventualy got away with perpetual check. It could be, as you once mentioned, a matter of hardware being used.

I didn't notice any instability or weird randomness in the Alekhine personality. It seems to play consistently for me. If you still have access to your friend's computer, you could check the settings for the Alekhine personality:

Also, you could play a game against Alekhine with the "Thinking Lines" window open. In a 10-minute game, Alekhine should be reaching a depth of something like 3/11 to 3/13 plies in a typical move, and over 5 million positions.

People winning computers are super humans.

We now see two people who claimed to beat computers, you and Mr Lyudmil.

In any chance, can you guys  do showmath?

We would like to watch and learn and also would like to know who is better.
