ECO Index D

Welcome to ECO Index D. It's the next part of the openings series after ECO Index C. Volume D deals with the Queen's Pawn Game, principally the Queen's Gambit, Declined and Accepted.

Later it moves on to the Neo-Grunfeld Defence. This idea is for Black to start by developing his kingside knight instead of playing a center pawn.

The concept is further investigated in the last 20 entries of the volume which consists of the Grunfeld Defence. This volume should give you ideas for ways to expand to openings repertoire, opening up fresh possibilities.

Moving On

The Queen's Gambit has many branches, there are not many who are intimately familiar with them all. The opening tends to lead to slow-burning strategic encounters.

The Accepted lines do not merit more than 10 entries as it is not considered to be Black's wisest choice. Most of the section as you have seen concentrate on the Declined lines and you will find that certainly these days Black more often than not declines this gambit.

The final part of the series is Volume E and this is another on the QPG. It looks at Black's Indian defences in the face of 1.d4, these are like the Grunfeld and the Neo-Grunfeld in that Black replies with 1...Nf6.
