It is frequently assumed that the Blackmar-Diemer Gambit is more prone to internal contradictions than any other opening in what is known as QueenÕs Pawn Game. It is certainly the case that analysts of the game only very rarely lower themselves to deal with an opening that international master Andrew David Martin famously likened to Òshopping for a tombstone.Ó When a categorically generous analyst stoops to consider the results of such a repertoire, they tend not in any obvious way to help the case of promoting the relevancy of BDG, or in providing unqualified criteria for classifying certain strands of it as relational or ancillary to a conservative view of an adequately played QueenÕs Pawn Game.
