More Teichmann Defense

My last post featured a BDG from the recent Senior World Chess Championship in Bad Zwischenahn, Germany. The game was a Teichmann Defense which went:

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 Nbd7 9.Qe2

As I wrote, 9.Qf3 is usually seen here. When I first played through this game Qe2 seemed new to me. I was surprised to find I'd actually published several games with it years ago in BDG World.

A natural question here is what happens after 9...Nxe5? In No. 52, the July-August 1992 issue, Steve Kelly annotated the game Nick Schoonmaker (2245) - Stevis Chakis (2165), G/20, played on the old GEnie network in 1992:

The text, along with its follow-up, allows White's pieces tremendous activity.
10.dxe5 Nd5 11.Nxd5 Qxd5 12.Bg2 

12...Qa5+ 13.Bd2 Qb6 14.0-0-0 0-0-0?

14...e6 is absolutely mandatory. Castling is usually done for safety, but the text is about as safe as running through a forest fire with a gallon of gasoline in each hand.
15.Be3 Rxd1+ 16.Rxd1 Qa5 17.e6!+-

White strikes the match, and Black at once explodes into flames.
17...fxe6 18.Bxa7 Bf7 (18...Qg5+ 19.Kb1 does not help at all) 19.Qd3 and Black cannot cover both d7 and d8. Instead, GEnie onlookers got to witness the most spectacular finish.
18.Rd8+ Kxd8 19.Qd2+ 1-0.
Black burns to a crisp, as 19...Kc8 20.Qd7+ Kb8 21.Qd8+ is mate.
