This brand new release of  ECO of chess openings holds over 4.5 million high class chess games, exactly counted 4506340 games and that is a
small 177.000 more games than the previous issue 2012.
A small 80.000 of these games cover heavy loaded  annotations, but the experts under us prefer  these ECO DVD’s  for the excellent made
theory surveys often taken from the well filled ChessBase Magazines.
For example A :Ruy Lopez Marshall

In my opinion the arising position is some kind of dynamic equality, but Black has more obstacles to find the right pass, so I'd pick White if had I been offered the choice! That's the best of evaluation I can come with at this late hour! 20...Nc7 21.Kg2 (Nothing promised 21.e5 Be7 22.Ne4 Nd5 23.Kg2 f6 24.exf6 Bxf6= and Black is fine.; 21.Nf3 Kg7 22.Be3 a5 23.a4 f6 24.axb5 cxb5 25.Bc2 a4 26.d5 Be5 27.Bc5± 1-0 Vachier Lagrave,M (2632)-Kurnosov,I (2593)/Plovdiv 2008 (46)) 21...c5!

Sam Collins explains on this DVD all kind of Philidor structures where the
white pawns are on d4 and the black ones on d6 and e5,and that includes position as the Spanish Game.
The modern player of today does not play the Philidor but prefers set-ups as Motylev,Alexander (2655) - Baramidze,David (2615) [C95]
