Hello CVO team, I have a question about the previous issue, #8. There you give very interesting statistics of the variation played in the 2nd match game Kamsky-Topalov, which went 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0-0 Bc5 and now you mention five 2500+ games with the move 5.Nc3 in your database.

But there is a tricky transposition to another opening line here which you seem to have missed, because when I look in my database at the position after 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bb5 Bc5 5.0-0 I get more than ten 2500+ games, not five!
So my question is: which of the two statistics is correct: the first one or the second? How are these transposition problems solved normally in chess statistics? I am curious what your opinion is.

Good point HJVFan, to be honest we didn't realise this move transposition to full effect and should have mentioned it. I'm curious if there are more people who noticed this omission!

In our statistics we basically describe how offen a MOVE has been played in the diagram position, not how often the resulting POSITION has been played.
In the analyses of the Game of the Week we should have mentioned this transposition to the Spanish Four Knights though.

Black is doing fine in this line, Emms even recommended 1.e4,e5 2.Nf3,Nc6 3.Nc3,Nf6 4.Bb5,Bc5!? in this solid repertoire book "Play the open games as Black" (2000). For example 5.0-0,0-0 6.Nxe5,Nxe5 7.d4,Bd6 8.f4 and here Emms gives 8...Nc6 and in addition the current database reveals 8...Neg4!? with nice play. White obviously wins back the piece, but Black has a very decent position.
