Black to move

White has just blundered by playing 1 Qe2-c2??, leaving behind the e1-mating sq, resulting in a pin against a square which Black exploits with 1 ... Rd4xNc4!, winning a piece as the White c3-rook is pinned against the e1-mating sq.

What do you know about this game? Players etc.?

You could run it through a database on the net and may find a match.

[jdart]

It's not in ChessBase MegaBase 2011 or Correspondence Database 2011. Could it be a composition?
