Wall, Bill - Mazloom
SparkChess, 2024
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6
Bill suggests the aggressive 9...Qh4 first
10.h3
He has also tried 10.f3, meeting 10...Kf7 with 11.O-O in Wall,B - Guest1105387, PlayChess, 2014 (1-0, 30) and 11.d4 in Wall, B - Guest3544144, PlayChess, 2013 (1-0, 35).

Bill has tried 10.Nc3 in Wall,B - Iverka, Sparkchess, 2024 (1-0, 26) and 10.O-O in Wall,B - Dasasary, internet, 2024 (1-0, 34)
10...Kf7 11.O-O Re8 12.d3
Mazloom has done well. Soon he will castle-by-hand. He is applying pressure to White's e-pawn.
Bill needs to remain diligent and find his moment.
12...d5 13.f3
Bill has deployed this Queen-behind-pawn-phalanx, in Wall,B - Guest1590349, PlayChess.com, 2020 (1-0, 44).
13...d4
It is tempting to harass the enemy King, but this allows White to expand his pawns in the center. Instead, 13...Kg8, completing his artificial castling, was to be preferred.
14.Qe1 Kg8 15.f4
In a funny way, I am reminded of a line that the Joker had in the 1989 "Batman" movie, where the villain, puzzled, said "Where does he get those wonderful toys?"
Bill's e- and f-pawns will cause havoc in Mazloom's position, making use of the mobile center that the first player has been gifted.
15...Qe7 16.Nd2 Qc5 17.Qd1 Bd7 18.Nb3 Qb6 19.a4
White is down a piece, and has only 2 of his pieces developed, compared to Black's 5, but Stockfish 16.1 evaluates the position as less than a pawn better for Black.
19...c5 20.e5 Nd5 21.e6
Bill shows his sense of humor: the pawn can be captured 3 different ways, but each would lead to the pawn fork 22.f5.
21...Bc6
Black wants none of it, but now the intruder can be reinforced.
22.f5 Nge7 23.Qg4
23...Ne3
After all, as we say in the Jerome Gambit Gemeinde, "Black wins by force; White wins by farce."
24.Bxe3 dxe3 25.f6
Those White pawns!
As the villains say in many Scooby Doo episodes ...and I would have gotten away with it too, if it weren't for you meddling pawns, er, kids...
25...Ng6 26. f7+ Kf8 27. fxe8=Q+ Kxe8 28. Rf7 e2
Okay, Black has a sense of humor, too. This pawn is going nowhere.
29.a5 Qb4 30.Qxe2 Nf4 31.Qe5 Black resigned
White's Queen has slipped by Black's pieces, and has a checkmate-in-8.
