One of the principal defences to the
Queen's Gambit, this opening was first mentioned
in 1590 but only became popular from the 1930's.
|Variations include the
Exchange Slav, the
Slav Gambit (for the Tolusch-Geller Gambit), the
Alekhine Variation, the
Dutch Variation and also opportune
transpositions into the Semi-Slav Defence (qv.)
(where Black's additional P-K3 support shuts in his QB and
usually leads to the Meran Variation).
