crafty learn file and openings

Could some of you who use crafty regularly email me your crafty.lrn file? I would like to import them into my opening file..
BTW what do you think is a good opening for crafty to play as black? I carried out a few 30 min games with crafty on the black side, and Anmon509 got a lot of good attacking positions as white against sicilian ..
Crafty used to like philidor (horrible) and centre counter as well..But now it settles between 1..e5 leading to ruy lopez usually or the sicilian..
I wonder what results i would get from importing learn results from the rest of you..If you contribute to Dr Hyatt's learn files please don't email me yours, since it will be in the learn file i get off his site..

Goliath likes the french, weird choice I would think..Comet and SOS usually go for sicilian..
PS phalanx and Anmon games are REALLY interesting..

How do you do that? I could read the Crafty.doc of course, but if you don't mind...
By using only books.bin Crafty plays the Petroff against 1.e4 e5 2.Nf3 instead of the Ruy Lopez. I also try to make Amy choose the Petroff.
The French is solid IMO, but sometimes Goliatg chooses the Dutch against d4. Interesting, but not exactly solid.
I agree, I like SOS games as well. Mostly unusual openings.

Okay..Whenever crafty learns anything new it records it in the crafty.lrn and AND the bookbin..
As such crafty.lrn is just a list of stuff your crafty has learnt..Deleting it as no effect since learning is included in your book.bin as well..
So by using the "import crafty.lrn" command from other sources you can imprint your book bin with other crafty learning..
The idea is that everyone should email to Dr Hyatt your oen crafty.lrn file and he puts up the total new lrn file from time to time including everything learnt from the crafty community..

Actually it's quite complicated if you contribute more than once to Dr Hyatt..
Say you give Dr hyatt your learning file and he adds it to the bookbin..
And if you download the new learning file from him again, you get the same learning twice..
To avoid that, you do this
1)email your crafty learn file
2)delete your crafty lrn file..You don't need it , since learning up to now is already in crafty's book..But deleting this file , allows you to send only new stuff to Dr hyatt in the future
3)Get the new lrn file from Dr hyatt
4)Use the command Import clear, this wipes your book bin of all learning and imports the new lrn file..Now import your existing learn file to include stuff that crafty has learnt AFTER the lrn file was sent to Dr Hyatt.
Complicated..Huh?




That's a safe choice..But boring to watch,.
French is solid, but goliath should play sicilian IMHO..More open positions for tactical play..
Yes..as white it plays flank openings..Provbably where the reputation of being positional comes from

Thank you for your explanation. I downloaded a book.lrn and imported it into the book.bin. Hopefully this will have an effect on the playing style of Crafty.

Not always and very few programs can handle the Sicilian correctly. If it was possible then a program should choose equally between c5, e5 and e6 against e4, which is what I'm trying with the Amy book. Not an easy task I can assure you.

can we exchange crafty.lrn files?

But wouldn't it be better for a engine to specialise in one and learn from it much like a human player?

I don't use Crafty that much right now, so the learn file is somewhat small and I just imported and erased the one I had. But at some point it might be a good idea. I just can't tell you when exactly.
Amy can't learn, which causes problems. The Amy book is built on human GM games, so it likes the Najdorf variation of the Sicilian a lot because it is a frequent GM defense. Sadly, very few programs can handle the complications of the Najdorf and lose more often than not. That's why solid lines are important for non-learners like Amy, Gromit or TCB. Another choice would be a very small book, where the program is allowed room to think for itself. But at shorter timecontrols this a definite disadvantage. Between a rock and a hard place you might say. Hopefully booklearning will become essential for all programs soon.

Okay what a pity..I would expect you to have a large book.lrn file..Anyone else? I'm going to collect as many as i can..
