Locock Gambit

[d]rnbq1b1r/ppp2kp1/3p1n1p/4P3/4P3/8/PPP2PPP/RNBQKB1R b KQ - 0 6

Cool opening for engine testing. The middlegames turn out to be quite imbalanced.

I play that in blitz games if I don't care if I win or not.

The opening is slightly worse than the cochrane. Nevertheless the middlegame complications turn out to be interesting.

Nothing on this "line" came up in a 2 million game database and I've never seen an example of it over the board in 50 years of chess playing..Therefore we must assume it is 100% nonsense...just where was this "opening line first played and in what events" Thx AR

The move 2 ... d6 is quite rare. Another more common sacrifice is:

Sacrificing a knight in Russian(petrov) defense.
