My first (and only) game aganst Fruit 2.3.1

[glorfindel]

It was a victory! I myself was surprised.

Of course, my hardware is not particularly fast. My AMD64 laptop running at 800 MHz, because else it is overheating. 5 mins / 40 moves, ponder off.

You took it out of book early with the unusual 7.g3 which is always a good thing. I only found one game between two 2300 rated Oberliga players where 7...e6 was played. This seems to be the logical reply.

Once out of book Fruit played of course horrible opening moves. Qa5,Na6,Qb6,Ng4 "plan" doesn't make any sense. Fruit might play these moves also on a fast machine. This is simply an opening some engines don't understand.
Supposedly much weaker engines like Colossus Chess and The King find 7...e6 without problems.

Generally IMHO rating lists based on Computer-Computer games don't tell you at all how strong an engine is against humans.

[Uri Blass]

It is clear that fruit can find e6 with more time

[swami]

Congrats, but I think Fruit is good particularly against other engines, You should try Glaurung or Spike if you want a strong engine for human vs engine match.

[glorfindel]

Perhaps you are right. I did play two games against the new Glaurung earlier, and I lost both of them.

But I feel that Glaurung also did not make things very difficult for me. Although I had bad positions early in both games, it let me off the hook at some point and I could even have won (esp. in the second game). I also drew my recent game against Toga. Maybe I will try Spike later.

Perhaps you are right. I did play two games against the new Glaurung earlier, and I lost both of them.

But I feel that Glaurung also did not make things very difficult for me. Although I had bad positions early in both games, it let me off the hook at some point and I could even have won (esp. in the second game). I also drew my recent game against Toga. Maybe I will try Spike later.

If you want more strong opponents to play with,
choose Slowchess (chessmaster like playing style)
King of Kings(good style although occasionally I defeated it but it is extremely difficult to play against,it is rated around 2550 in engine rating list)

They both come with their cool GUI's. King of Kings GUI is compact and good.

Toga and Fruit are just not that great against humans, it is extremely good against other engines.That's why they are described as skeptical programs.

Well I play on a correspondence chess server (that allows use of engines) with Fruit as my only computer engine reference and have not lost a game in 49 completed games so far. I would think an engine would have to be good vs. both people and the engines like Rybka and Hiarcs that opponents mention using as reference. I would of course take you a little more serious if not for your examples both being of engines that are very good tactical engines that have high potential of struggling with positional understanding or choking on a material imbalance that the human could bring into play.

I was just stating my opinion, Fruit is extremely great against other engines, but it doesn't play at the same level when playing human, it's skeptical program and most of the human Grandmasters are also skeptical.

I played quite a few games against Toga and without taking back any moves I could hold out a draw,that too in a blitz game of 1/1.

I guess it has something to do with the style.Maybe at the longer time controls or in Correspondence chess, it plays well.

Swami, where would i find this King of Kings? IM guessing with a gui its not freeware. And are there a number of levels to compete against? I have found that i am spending too much time testing at the expense of my game. I need more practice. Sometimes CM gets old.

Thanks in advance,

Hi George,

As I said, The GUI is cool and compact.Tell me what your opinion about it is,after you have played few games.

Back in college, I used to play against this engine a lot, It was quite a fun.

Regards.
