Open Ruy Lopez

I would really appreciate if anyone found anything about the end position and help me find whites best move.

I ran the game in this site's Game Explorer.  With Black to move at 8 Explorer gives black a superior win position choosing either to castle or e4 but there are very few games in the database at this point and the majority are draws.  Your computer however comes up with a move that isn't in Explorer.  I don't play this particular path so I have never seen it.

Perhaps the computer is out of book and simply perceives this to be a stronger defence.  You don't say which computer you are using or what settings you are have.  I'd expect the latest computers to have book openings at least up to this point.

Looking at the move 8 ...Bd6 it looks to be quite sound defensively as castling, whilst the most played move, might be premature.  I'd prefer d4 but you can end up with a doubled pawn if the bishop takes the knight.  However Bd6 does lock up black's further development and gives White a chance to develop.

I'd probably play c4 at this point giving protection to both bishop and knight.  I suspect black will respond with b5 forcing your bishop away and allowing his bishop to develop

i havent palyed the ruy lopez in a while but i think that 6. d4 is the main line.

Re1 is playable but after Nc5 i think Bxc6 is the only way to keep a slight advantage.

I think that 8. Bd6 is a good move. you wasted a move playing Nd5, now your knight is misplaced and you are forced to give up the bishop pair which is probably why black has an advantage.

That is very odd. I have no idea how to respond to that either but have you checked chessgames.com? I don't know if that will help but it seems like they have a very large database, they might have a response to that problem. What I'm not very sure about is that how will this help the computer?

Thank you for your observations! 

This game was played between me and a computer named Novag Jade from 1992 (almost as old as I am) at about 40 moves in a hour.

My observations about the position is that now would it be ok to take the bishop which before was a trap and I have no way to take advantage of the strange bishop  two move maneuver. White now needs to protect all his pieces and it will be blacks move. All databases I have found recomends 8. ..., e4 but the computer obviously do not agree.

chuckles you are completely right when you say that 6. d4 is the main line but according to all my sources is 6. Re1 almost as strong and I like the hanging bishop trap so I use to play it. Now I am not sure, maybe I should change my preference to 6. d4 instead.

mvh Fredrik 

I have always believed the 6. Re1 line to be as good as the d4 line but slightly more beautiful with a hanging bishop but now I see that this is not the case.

Cloyescapade thank you for your hypothesis but we should take into consideration that the computer is from 1992! How could it find such a good waiting move that takes into consideration long term strategic ideas.

mvh Fredrik 

I have developed an idea during the day, what about:

9. Bxc6, dxc6 10. Nxe5, 0-0

My point is that black cannot take the d5 knight because he would loose the queen and after black's 10th move which probably is to castle can white just retreate the bishop.

I really do not want to abandon this line, I love it. 

What do you think?

  interesting open ruy lopez

  who do know good books about this open ?

 thanks you

is supposed to be a very good one (for black as you can see :) ).

Anyway, for whatever little it is worth, Houdini thinks Bd6 leads to +0.39 for white:
9 d4 Na4
10 Bg5 Nxb2
11 Bxd8 Nxd1
12 Bxc7 Nc3
13 Bxd6 Nxd5
14 Nxe5 Nxd4
15 Ng6+ (depth 22) 

About an hour later houdini was at depth 25 and said it was .75; I don't remember the line but it started with d4 Nxa4 but differed somewhere.
