Larsen's Opening Hastings h-file Mate

Yesterday I posted the Hastings h-file Mate from a Ruy Lopez. Today I show a recent example of how I pulled off this same mate as Black in a Larsen's Opening (1.b3). As I pointed out before, this mate arises in many different openings. All the same elements are in place in the game below, but they occurred in a slightly different order. For example, White moved Kh1 before Black played ...Ne2, so the knight move was not check here.

As for the opening, how do you meet Larsen Opening? I followed the recommendation of GM Roman Dzindzichashivili from his book with GM Lev Alburt, GM Eugene Perelshteyn and Al Lawrence: "Chess Openings for Black, Explained", 2nd Edition Revised and Updated from 2009. There they give 1.b3 d5 2.Bb2 Bg4 3.h3 Bh5 4.Nf3 Bxf3 5.exf3 Nf6 6.f4 e6 7.g3 g6= Spraggett-Dorfman, 1991. My ICC blitz opponent "Arieju" played 3.Nf3 so I chopped off the knight doubling White's pawns. I played in the center and gradually moved my pieces toward White's king when the h-file mating pattern presented itself. Also you should note that I played 19...Qh6 rather slyly (instead of 19...Qh4 which would have encouraged 20.g3) because I did not want White to move a kingside pawn.

Arieju - Sawyer, ICC 3 0 Internet Chess Club, 27.01.2013 begins 1.b3 d5 2.Bb2 Bg4 3.Nf3 Bxf3 4.exf3 Nc6 5.c4 d4 6.Na3 e5 7.Bd3 Bd6 8.0-0 Nge7 9.Nb5 [9.f4!?] 9...0-0 [9...Bc5] 10.a3 [10.Nxd6=] 10...Ng6 11.Nxd6 Qxd6 12.a4 Rfe8 13.Ba3 Qf6 14.Be4 Nf4 15.Kh1 Rad8 16.b4 d3 17.Bb2 [Better is 17.b5 Nd4=/+] 17...Re6 [Or 17...Nxb4-/+ ] 18.Bc3 Ne2 19.b5 Qh6 20.bxc6? [To survive White had to push a pawn, as in 20.h3 Ncd4-/+] 20...Qxh2+ White resigns 0-1
