There is an advantage to studying an opening and playing it regularly. At the very least, it provides strategic ideas (from which flow tactics).
The following game is an odd example - even without finding the best moves, in a familiar opening, White is able to stumble toward a win.
perrypawnpusher - rffuse
3d/move, Chess.com, 2026
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5
Black can now choose Blackburne's defense, 7...d6, or Whistler's defense, 7...Qe7.
Against the Blackburne, White can take the Rook and, after adventures, probably draw.
Against the Whistler, White takes the Rook at great peril.
7...Qe7 8.Qf4+ Qf6
Or 8...Nf6 as in perrypawnpusher - F0nix, 3d/move, Chess.com, 2021, (1-0, 16) and perrypawnpusher - accattone444, "Jerome Gambit Classic #1" Chess.com, 05.2024 (1-0, 44); or
8...Kg7 as in perrypawnpusher - tmarkst, blitz, FICS, 2009, (1-0, 43)
9.Qg3 d6
Or 9...Ne7 as in perrypawnpusher - joro_videv, 3 d/move, "Giuoco Piano Game", Chess.com Chess.com (3), 2022 (0-1, 34); perrypawnpusher - atastypawn, "Italian Game" tournament, Chess.com, 2024 (0-1, 30); perrypawnpusher - yaku, blitz, FICS, 2011 (1/2-1/2, 26);
10.c3
Or 10.Nc3 as in perrypawnpusher - alvarzr, blitz, FICS, 2014 (1-0, 49)
10...Bd7 11.d4 Bb6
12.Bg5 Qe6 13.f3
I have seen Bill Wall (who knows a lot about chess, and the Jerome Gambit in particular) adopt this pawn formation, awaiting his opponents' tries.
Stockfish 17.1 rates Black (32 ply) as about 2 1/2 pawns better - but it is only an advantage if you do something with it.
13...c5
Attacking the center while White's Queen and dark square Bishop are away from home. Still, there was something to be said for 13...Nf6.
14.d5 Qe5 15.Bf4 Qh5 16.Bxd6
16...Nf6
White has three pawns for the sacrificed piece, and those "Jerome pawns" are beginning to look dangerous.
Black has better development, but this is offset by the uneasy position of his King.
17.Nd2 Rhe8 18.c4 Kg8
Safety.
19.O-O
Stockfish prefers castling long. I never even thought abou that.
19...Rad8
20.e5
Here we go.
20...Qh6
You attack my Knight, I will attack yours.
21.f4
Consistent, but not best. Instead, the position called out for 21.Ne4.
21...Nh5
Moving to safety, and repositioning for defense.
Because of White's slip on the last move, Black had the equalizing 21...Bf5 (You capture my Knight, I will capture your Bishop) instead.
22.Qf3 Ng7 23.Ne4
23...Kf7
The King moves away from the threatened Knight fork
24.Nf6 Rh8 25.Nxd7 Black resigned
If 25...Rxd7, then 26.e6+, forking King and Rook.
