In the recent Moscow Open Yu Yangi decided to turn a Goring Gambit (a surprise in itself) into a line of the Danish Gambit, by offering the b2 pawn, instead of playing Nxc3. He then proceeded to successfully hack his 2550 rated opponent, in a manner fitting the choice of opening. However there is one question that nags me. Is the fact a GM has played the Danish means it is now sound, or is it simply a function of the number of GM's we now have?
