Fun Distraction

I COULD not help but be distracted by the game played on a board next to me during Battersea 2's 8-2 promotion-sealing win against Wanstead & Woodford 2 on Wednesday night.
Paul Stokes (158) - Paul Haddock (128)
Englund Gambit
1.d4 e5?!
This is the Englund Gambit or, as I like to think of it, a Blackmar-Diemer Gambit with colours reversed and a tempo less. Either way, it is just about as unsound a move as is possible on move one. The gambit is named after rich Swedish amateur Fritz Englund, who did not invent it but sponsored a tournament where the games had to start 1.d4 e5 2.dxe5 Nc6 3.Nf3 Qe7 4.Qd5.
But if the gambit really is unsound, why does anyone play it? Well, the lines can be a lot of fun, there is always the possibility of White falling for a diabolical trap, and anyway it takes precise play to bust Black.
For what it is worth, the analysis engine Stockfish10 reckons White is already winning after 1...e5?!, but Komodo9 gives White only a slight edge.
2.dxe5 Nc6 3.Nf3 Qe7 4.Bf4
If 4.Qd5, as in Englund's themed tournament, Black gets interesting play with 4...f6 or 4...d6.
4...Qb4+ 5.Bd2 Qxb2
Black now lives in hope that White will not see the trap that has been set for him.

White faces a critical choice at move six

6.Nc3
Not 6.Bc3?? (the second-most popular move in ChessBase's 2019 Mega database) as 6...Bb4 wins for Black. The mainline from here in Mega19 runs 7.Qd2? Bxc3 8.Qxc3? Qc1# - no wonder some people think the Englund is worth a punt!
6...Nb4?!
The main move is 6...Bb4, as once played by Paul Keres (he lost in 34 moves). The text is inferior … if White finds the best reply.

White to make his seventh move

7.Rc1?
This lets Black back into the game. Correct is 7.Nd4, eg 7...Bc5 8.Rb1 Qa3 9.Ndb5 Qa5 10.a3, with a massive advantage for White. But it is still possible to go wrong - one game in Mega19 went 10...Qb6 11.axb4?? Bxf2# (Pal Eros - Michael Keane, IBCA blind olympiad 1976).
7...Nxa2 8.Nxa2 Qxa2 9.e4 f6?
This seems to be a novelty, and not a very good one. An American player rated around 1500, Jerry Simpkins, has two games in Mega19 that reached the position after 9.e4. In the first he played 9...d6, and in the second he played the engines' choice, 9...Bc5.
10.Bd3
The engines believe 10.exf6 to be even stronger, but helping Black's development would give him practical chances.
10...fxe5 11.Nxe5 Nf6 12.Bc4 Qb2 13.c3 Resigns
White's huge lead in development more than compensates for his pawn-minus, but Black's resignation struck me as the most surprising 'move' of the whole game.
