Bischofsgrün Round Three

Manfred Herbold (2105) - Spanton (1942)
Scotch Four Knights
1.Nc3 Nf6 2.e4 e5 3.Nf3 Nc6 4.d4 exd4 5.Nd5!?
This is the Belgrade Gambit, first played by Kurt Richter in the 1938 Germany-Austria match at Berlin, where he lost to Albert Becker. The gambit was taken up and apparently given its name by a Yugoslav player, although sources vary as to whom.
How should Black respond?

5...Be7
Richter-Becker went 5...Nxd5 6.exd5 Bb4+ 7.Bd2 Qe7+ 8.Be2 d3!? 9.cxd3 Bxd2+ 10.Qd2 Nb4 11.0-0 0-0, with at least a slight edge for Black, according to Stockfish16 and Komodo14.1 (0-1, 32 moves).
Grabbing the pawn with 5...Nxe4 is possible, eg 6.Bd3!? (the engines prefer this over the commoner 6.Qe2) Nc5 7.0-0 Ne6!? 8.Re1, when White has sufficient compensation for two pawns, according to the engines.
The text is the most popular move in ChessBase's 2024 Mega database.
6.Nxd4 Nxd4 7.Qxd4 Nxd5 8.exd5 Bf6 9.Qe4+ Qe7 10.Qxe7+ Kxe7!? 11.Bd3 Kd6!?
This may be too ambitious. Black should perhaps be content with 11...Re8 or 11...d6.
How should White proceed?

12.c4
The engines suggest 12.0-0!? or 12.Bf4+, eg 12.Bf4+ Be5 13.Bxe5+ Kxe5 14.0-0-0, with what they reckon is a slight edge for White.
12...Re8+ 13.Kd1 Ke7 14.Re1+ Kf8 15.Rxe8+ Kxe8 16.Kc2 Kf8 17.Bf4
17.Bxh7!? g6 18.Bh6+ Bg7 19.Bf4 is completely equal, according to the engines.
17...d6 18.h3 Bd7 19.Re1 Re8 20.Rxe8+ Bxe8 21.b4 Ba4+ 22.Kd2 h5 23.Bf5 Ke7 24.Bc8 b6 25.b5 g6 26.g4 hxg4 27.hxg4 Bd4 28.Bg5 Bf6 29.Be3 Kd8 30.Bb7 ½–½
