If you haven't met this spendid opening before, do check out Tom
Purser's BDG
World magazine for games, variations, stories and a chance to
meet the characters of the BDG community.
The opening is named for Blackmar, who described
the gambit 1. d4 d5 2. e4 dxe4 3. f3 , and for
Diemer, who improved the line by avoiding the defence
Many of the posts here on r.g.c.a. take the form "what should I
play against..." or the related, but very different,
"what's a good line against...". I've been thinking about
this a lot lately, both for myself, and, more especially, for my
students, who range in strength from beginner to class A, and I've
come up with some thoughts that I'd like to share and invite
feedback on.
Get your pieces out
into the
centre quickly. The opening is a
race to see who can get their pieces out first while
keeping at least
a share of control of the centre.
This is the main point to remember; all the other
rules are
just
footnotes to this one. Sortez les pièces!
Get a firm foothold in the centre - a pawn on one of the
'little
centre' squares e4/e5/d5/d4 - and don't give it up without
good reason
