Ruy Lopez patterns

The Ruy Lopez pattern is the following thing :

1. the symmetrical dQB-opening on the 1st move
2. a white knight's attack on the black dQB-pawn and its defence by a black knight
3. a bishop's attack on the black knight defending the dQB-pawn

This is generally a very good opening in all chess960 games. Here it goes :

Actually, it seems that BBNQRNKR is the first chess960 initial position where Ruy Lopez occures. Sigma gives +0.23 to black if it replies 3.b6 :

Here's the second occurency in BNRQKBNR game, Sigma gives -0.11 to black if they play 3...Nd4 :

Okay, this evening I'm planning to make the list of all Fischer's positions where Ruy Lopez occures!

If you make a PGN database, it would be a valuable resource.

Do you really think that every opening where a Bishop occupies a square diagonal to a Knight is Ruy Lopez, or are you joking ?

Actually, it's very easy. It should be a position containing one of the following FEN strings:

• BNQXN
• NBXQXN
• NXQNB
• NXQXBN

Atos, please read attentively my first post to understand what is true Ruy Lopez. There are 4 conditions:

1. Symmetrical dQB-opening
2. White knight attacking the black dQB-pawn
3. Black knight defending that pawn
4. White bishop attacking that black knight

 Hey Ozzie, I could make it, especially if U wanna help me.

In principle it is a worthy task.

But.

I have various preparations of this sort already ongoing for my private lessons, so sorry. :-(

Okay, let's enumerate BNQXN-positions, an example is given in my first post:

1. BBNQRNKR
2. BRBNQKNR
3. BRKBNQRN
4. RBBNQKNR
5. RBNQBNKR
6. RBNQKNBR
7. RBNQKNRB
8. RKBNQBNR
9. RKBNQRNB

If U wanna an illustration of one of those Ruy Lopez games, pliz tell me.

 No problems.

 Okay, here's an illustration of RKBNQRNB Ruy Lopez:

And what would make this a Lopez and not, say, a Veresov ?

Richter-Veresov is the same pattern in vQB-setting (Ruy Lopez in dQB).

dQB = diagonal Queen/Bishop pawn's opening (e4 in standard chess)

vQB = vertical Queen/Bishop pawn's opening (d4 in standard chess)

bump, to be continued today
