In the weak but trappy Englund Gambit, after 1.d4 e5? 2.dxe5 Nc6 3.Nf3 Qe7, White's two best moves are 4.Bf4! and 4.Qd5! In either case, however, White must know what he/she is doing. As the game below shows, combining the two ideas can be disastrous. On White's fifth move, correct was 5.Nc3! Bb7 6.Bg5, forcing Black to make his pawn sac permanent with 6...f6 7.exf6 Nxf6. Instead, 5.Bf4?? lost material to 5...Qb4+!, forking White's bishop and b-pawn. If White had responded with 6.Qd2 Qxb2 7.Qc3, 7...Bb4 would win the queen for starters. In the final position, White loses either his rook (after 9.Nxc3 Qxa1+) or king (after 9.Qxc3 Qc1#).
Note that the player of the White pieces reportedly died three years ago. Apparently, as with Mark Twain (and Elvis?), the rumors of his death have been greatly exaggerated. Or perhaps there is life, and Internet access, after death.
