Originally posted by SicilianNajdorfLIke I said, a3 may not get it out of the book immediately, but it will FAR sooner than e4 or d4. Also, although a3 is a weaker move, the computer will probably not find the best response on the next move, or at some point because it's out of book. I'm sure it does have an opening book against Andersson's, but it won't be as extensive as most of the others. The reason I pick a3 is because it's a move that does a little good, but does really cause any harm to our position. It's especially good if we end up transposing to the black side of a sicilian, as it's a common move. The other moves are more aggressive, and could cause harm to our position, as well as question our opening knowledge. When we play a3, the position is still very similar if we were black, and we hadn't played it. So we can use our opening knowledge, but the program can't.
To ark :
Okay , so a computer has an opening book and thinks differently from a human , and like I said , it triggers through all the possible outcomes to find the most favourable position for itself . That explains it has an opening book against 1.a3 Andersson Defence , doesn't it . It even has a powerful defence against 1.b3 and 1.a4 and 1.b4 , ...[text shortened]... out of the book , and if it doesn't get him out of the book , for what reason do we play 1.a3 ?
EDIT: post in response to SeVeS
Yes, you are correct. If we play a3 we're essentially making Fritz white. But that's not so bad, is it? Anyone can win and draw as black. You're just at a slight disadvantage.
Since you said you're open to discussion, I'd encourage you to go for the Colle system.
c4 leads to a more open game which we don't want. c4 is also the most common move, and will be keep the computer in opening book for a longer period of time. The argument that c4 is studied is in fact arguing against us. We need to play something unstudied, and use our superior creativity against Fritz. It's the only weapon we have against silicon.
The Colle system is perfect against the computer. It's an opening with little to no tactics, but a plan. White's play is all based upon a couple of common plans. Most humans know these plans, and so can deal accordingly when playing against the Colle. But the computer doesn't know these plans, and we will easily be able to take advantage of it with slow, building play. I doubt that the computer will be able to see deep enough to find a plan for its own, and will thus make pointless moves as computers do in closed positions. This is really our best chance to get a result. However, it looks like c4 will win.
We don't want to meddle with the computer's theory on openings. The best way to beat this machine is by extending hos choices to millions . That , way , he'll be stuck on moves and take more games . That's why we need open games where are pieces and his have more options . I'm a bit tired of continueing this debate now . 1.a3 can be confidentally treated as a "medium" rated move but mind that a computer will play its defences to 1.a3 as if 1.a3 was not played . This may sound odd , but my DOS based program , plays very postionally rather than tacticlly , as you know , every computer has its unique strengths.
1 hour left before 2.c4 is made .

However, on your other point, it's common knowledge that computers play strongest in an open position, and weakest in a closed one. There's no debate about that, it's a fact. If you want me to explain to you why this is, I will. But it's also something that you can just look up. Therefore, we should try to get into a closed position.
The queens gambit is known terrain both by us humans and by the computer. It is however an opening in wich black has several defence variations to choose from. It is also more open than the Colle-system. This to me is a very good reason to adopt the Colle. However I've no experience at all with the Colle-system. I am willing to try it out however. It doesn't seem to matter but just for the record I change my vote to 2. Nf3
--SEVES
Fritz 9 / CHESS has made it's second move hence taking 0.7778482
seconds . It has made the move , 2...Nc6
Notes : The Chigorin Defence , I am sure this computer is very powerful although many of you will start to ask why it made such a weird response to 2.c4 . Once again , skims ,or someone else , can you post the FEN board position becuase my computer has some problems doing that .
Game history :

Originally posted by SicilianNajdorfWell, at least it'll be interesting. Keep in mind that the Chigorin is very tacitical, so we need to be careful.

OK, database: 3. Nf3 is the most common move, scores at 61%, and seems logical. It allows us to play 4. cxd5 next move, and then kick out his queen. He'll clearly do something about that. The only good scoring responce for black is 3... Bg4. Then we have c4. xd5 Bxf3 5. gxf3 Qxd5 6. e3. We force the bishop pair and control of the center at the cost of double pawns and development. We score 59% in this position. 4. Nc3 scores 62%, and will lead us into a relatively normal position.
Will also have 3. Nc3 which also seems logical. It scores 61%, is less common than 3. Nf3, but played by higher rated players. He has 3... dxc4 and 3... Nf6.
Originally posted by SicilianNajdorfI don't have a vote yet. I was just giving the database information. 3. Nc3 e6 scores poorly for black. He should respond 3... Nf6
Yes ,we must get immediately prepared to take his piece.If we play 3.Nc3 , we will defend and raise his solidity with 3... e6 You are correct ,arc . 3.Nf3 , I vote for it .
2 for 3.Nf3
