The Following Blackburn Shilling Jerome Gambit game features a King hunt, and a very uncooperative King.
White eventually corralled the monarch, but not without effort.

The Blackburn Shilling Jerome Gambit.
4...Kxf7 5.Nxe5+ Ke6
The King can also retreat with 5...Ke8, as in Nater - Rogers, Ballarat, 1975 (0-1, 46).
6.c3
This is the right idea, and it tempts Black to pursue material.
6...Kxe5
Of equal strength is 6...Nc6, e.g. 7.Qg4+ Kxe5 8.d4+ (8.Qf5+ Kd6 9.d4 Nce7? 10.Bf4+ Black resigned, anilone - butilicapetrica, lichess.org, 2024) 8...Kd6 9.e5+ Nxe5 10.dxe5+ Kxe5 11.Bg5 Nf6 12.Qf4+ Ke6 13.O-O d5 14.c4 c6 15.Nc3 Bd6 16.cxd5+ Kf7 17.Qf3 Rf8 18.dxc6 bxc6 19.Qxc6 Be6 20.Rad1 Ke7 21.Ne4 Qd7 22.Rxd6 Qxc6 23.Rxc6 h6 24.Bxf6+ gxf6 25.Re1 Kf7 26.Nd6+ Kg6 27.Rxe6 Rab8 28.b3 a5 29.Ne4 a4 30.Nxf6 axb3 31.Nd7+ Kg7 32.Rg6+ Kf7 33.axb3 Rfd8 34.Ne5+ Kf8 35.Rcf6+ Ke7 36.Rf7+ Ke8 37.Rg8 checkmate, anilone - fhat31, lichess.org, 2024.

7...Kxd4
Taking the bait. In 212 games in The Database, White now scored 65%.
Taking the e-pawn was no solution, either, e.g. 7...Kxe4 8.Qh5 Nf6 9.Qe5+ (9.d3+ Kxd4 10.Qb5+ Kxd4 11.Be3+ Ke4 12.Nc3 checkmate) Kd3 10.Qe3+ (10.O-O!?)

8.Qh5
Cutting the enemy King off from returning to his home is a good idea, although it is not the best one. Instead, 8.Nc3 was seen in 13 games in The Database, with White scoring 72%.
Such an exposed King surely must get checkmated!
8...Nf6 9.Qg5
Keeping the enemy far afield, and an improvement over 9.Qb5 c6 10.Qa4+ Ke5 11.d4+ Kxe4 12.Nc3+ Kf5 13.d5 Qe7+ 14.Be3 cxd5 15.O-O Kg6 16.Bd4 Qb4 17.Qc2+ Kf7 18.Bxf6 gxf6 19.Nxd5 Qc5 20.Qf5 Bg7 21.Rac1 Qa5 22.Rfe1 d6 23.Re7+ Kg8 24.Rxc8+ Rxc8 25.Qe6+ Black resigned, anilone - Wacwacnepo, lichess.org, 2023.
9...d5
This is an all-around useful move for the defender.
10.e5 Qe7
Black pins the e-pawn, but this move neglects the safety of his King. Better was 10...Kc5 11.d4!? Kc6 12.O-O Be6 13.exf6 Qxf6 with continued equality.
11.Qe3+ Kc4
12.Qc3+
Instead, 12.Na3+ would force the win of the enemy Queen with 12...Qxa3 13.bxa3, because 12...Kb4 would allow 13.Qc3+ Ka4 14.b3 checkmate.
12...Kb5
The King keeps trying to escape. White could now try 13.a4+ Kb6 14.a5+ Ka6 15.O-O Ne8, but Black would have an edge. Frustrating!
13.Na3+ Ka6
A slip - and a fatal one. Still good for Black was 13...Kb6 14.Qb3+ Qb4 15.Qxb4+ Bxb4 16.exf6 Bf5 17.O-O gxf6.
14.Qd3+ Kb6 15.Qb5 checkmate
