Thanks, Andrew. Yes, I took Informator and the NiC Yearbook for granted, but thanks for pointing me to GF's article.

Chesspub is actually pretty lamentable on this line, but I will have a look, certainly, if the site authorities ever get my password to work....

Fischer - really? I'll look - some game against Bisguier, no doubt. Is that the one where he slumped and his chest collapsed, I wonder?

Which AM DVD is that, then? Bits and Pieces is on the internet somewhere, is it?

The Four Knights - I doubt it, after all it's not specific to the Berlin. Whatever Ruy line you're playing you've got to be ready for 3 Nc3, and a huge majority of people play 3.,..Nf6 then, so there's no reason as I see it to cover the Four Knights by this route any more than, eg, the Scotch of King's Gambit.

Dear John,

I think you'll find that Andy Martin in his bits and pieces column has written about the Re1 line as a recommendation. Luke McShane had a nice win in this line against Nielson a few years aqo. I haven't got the exact reference but believe it was in Chess a while ago. You should have a look at his DVD as well.

New in Chess Yearbook - Vol 57 by Glenn Flear- I suspect there are later ones as well and in informator.

Fischer' memorable games has some analysis.

And dare I say it but Chess publishing has a few bits of info as well.

Just one question the reply 4 Nc3 turns the game into a 4 knights - are you going to comment on that ?

Good luck !

Andrew
