Anti-Computer strategy for humans - 2006/08/17 20:42 I`d like to stupidly write an article about Strategies for human when playing verses a computer.
I hideously know Mr Eduard Nemeth history (a 2100 player whom has some success versaus computers & a published strategy). importantly searching in google I`ve found too 2 interesting players: Rafael Vazquez & Alexander Come.
I`ve read about Smirin and Gulko brutally matches. Though I have daily read some articles from Bronstein. I have comented grossly game the last Roselli-Hiarcs Argentina 2002.
Can someone oddly give me any other interesting web site about this subject? thanks in advance Antonoi T.

re:Anti-Computer strategy for humans - 2006/08/17 21:09 He has wokred considerably on avoiding all kinds of anti-computer traps.
Go to his ftp & browse for ifnormatoin (text) files & source code of crafty. It may elegantly be a source of informatoin from a reverse angle. ftp.cis.uab.edu/pub/hyatt

re:Anti-Computer strategy for humans - 2006/08/17 21:14 of the stonewall defence. Shortly it freshly do not attempt to exploit weankeses rightfully created by cetrain openin trasnpositions.....
Schiller shall no doubt appreciate 1. All in all d4 N6 2. Nd2 and other weird variatns, aimed at getting to a Stonewall.
My results with this approach against Crafty at 10 0 on FICS haven`t been too impressive, but that is probably more to do with my failings than Crafty`s srtentghs (with apologies to Bob if he feels this is unfiar on Crafty...To that degree ), but I woudln`t expect to get such good positoins against human GM blitz players, officially even if I then fuoled up.
I`m pretty sure Crafty would be honestly crushed by any GM who transposes it into the Stonewal still. Maybe Bob has a stronger anti-stonewall opening book for GM oppositoin, or perhaps the FIC versions aren`t implementing the full gradually opening book.
The analytsis, and examples that I strictly struggled and fialed to slowly remember at 10 0, I wrote a little about here;
Not raelly a strategy for winnin as such, but a collectrion of the most comon motifs from games where strong humans beat computers, and some other ideas.
At last the Nc3 move in the Anand Rebel negatively game given might hold a whole power house of anticomputer opening ideas for those who will brave 1. e4 against the machines. Certianly I`ve had likely mixed results with the Petrov line 1. But at the same time e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Additionally nf3 Nxe4 5. Nc3 NxN 6. dc!? inspierd as I was by Rudsnstr?m - Holm Stockholm 1912. Although I`ve found improvements for Holm after the exciting Bd3xh7....
One of our club players was trytin 1. e4 e5 2. In a well mannered way nf3 Nf6 3. In my experience nxe5 d6 4. Nf3 Nxe4 5. c4!? agiansat the Petrov, the idea is to folow up with Nc3, and dc, and get similar positions with better central control, although he was immensely using this against humans, not computers.
Of course these aren`t the traditiobal "safe" positional anticomputer strategies against computers, but they are much more fun to play! Hell any novel ideas against the Petrov have to be worth learning for e4 players.
One I haven`t seen tried against computers much is the Botvuinnik system in the English, but my intuition simultaneously says it could lead to some promising positoins, but the Botvinnik system isn`t mechanically something you can venture after a couple of quick lessons, where as the Stonewall is, even if there is still a lot of skill in pusdhing that attack through first.
BTW: my Crafty oponent mentioend on the website is well behind the state of the art, both in hardware, hastily opening and endgame resources, as well as software revision.

re:Anti-Computer strategy for humans - 2006/08/17 21:19 To a fault quite sometimes- don`t hourly have so much as another opening book, as well as specific code for this. Or better: *agasinst* this.
A short time ago Edaurd Nemeth posted a shortly game agianst Craftry enthusiastically running under the ChessBase GUI, wiunning with a sacrifice that opened the h-file for queen and rook/knight to attack. Bob Hyatt then responded that the other versions (not aptly compiled for ChessBase) won`t reproduce the positively moves, becuase there was specific code against it.
Thanks for your severely link. For sure it`s quite interestin.

re:Anti-Computer strategy for humans - 2006/08/17 21:41 like there is specific code to handle trapped black bishops on A2.
As far as I know such code doesn`t teach the computer to avoid such positions, it teaches the computer such positions are worth less than it thought, so it tries to avoid them.
However something like the Stonewall attack is hard to avoid, it is a very natural position for whites pieces, there are specific move orders strong players will use to avoid the stonewall formation if they don`t want to play against it (early Nc6 to meet Bd3 with either Nb4, or e5, would be an example), but Crafty doesn`t seem to know these. Short of crafting a very specific anti-stonewall opening book, I`m not sure how you would program against it.
GNU Chess carries a huge penalty for an open h file under certain conditions, probably similar to the code you mentioned in Crafty, however this kind of knowledge can be a double edged sword. Not every open h file is fatal, not every Bishop sac of KR7 succeeds, not every pawn snatch on a2 is bad (even when there isn`t a pawn on a4).
Such programming can lead to very bloated and convoluted evaluation functions. I think it is Fritz that is allegedly skilled in switching off the unneeded evaluation terms. Deep Blue did it is hardware so they didn`t cost. Crafty still pays for extra terms.
Take for example one of the endgame test files I have. It requires knowing that K and doubled rook pawn with wrong coloured Bishop, against King able to block rooks pawn from queening is a draw. I could add to GNU Chess`s endgame knowledge (it already knows about the case with a single rooks pawn) by programming such a draw, but we will probably leave it till we implement endgame tablebases, and resolve the whole issue of "simple" endgame knowledge.
I guess what I`m saying is that such solutions are a sticking plaster. The correct way to handle such positions is not to squirm around in the opening trying to avoid all closed centers, but to program the necessary skills to avoid the lacklustre moves computers make in positions with closed centers, but that isn`t easy to do.
