Bavarian International Round Eight

FACED a German junior (born 2013).

Ruben Serwane (1561) - Spanton (1858)
Scandinavian
1.e4 d5 2.exd5 c6!?
A rare gambit whose chief merit is surprise-value.
3.dxc6 Nxc6 4.h3!?
Objectively this cannot be best, but it has the practical merit of almost certainly taking the opponent out of preparation.
4...e5 5.Nc3 Nf6 6.Bc4 Bc5 7.d3 0-0 8.Bg5 h6 9.Bxf6 Qxf6 10.Ne4 Qe7 11.Nxc5 Qxc5
White has simplified the position to an extent, but Black's lead in development gives full compensation for a pawn, according to Stockfish16 and Komodo14.1

12.Bb3 a5 13.a4 Nd4 14.Bc4 e4
Black is better after 14...Be6!, the point being 15.Bxe6? loses to 15...Nxc2+.
15.Ne2 exd3 16.Bxd3 Re8 17.0-0 Nxe2+ 18.Bxe2 Qe5?
This forks the white bishop and b pawn, but there is a complete answer. Instead 18...Bf5 is equal, according to the engines.
19.Bb5 Re6?
Black cannot afford to give up the back rank, so had to play 19...Rf8.
20.Qd8+ Kh7 21.Rae1 Qg5?!
Probably better are 21...Qf6 and 21...Qd6.
22.Qxg5 hxg5 23.Rxe6 Bxe6 24.Rd1 Rc8 25.c3 g4!? 26.hxg4 Bxg4 27.Rd4 Be6 28.Bd7 Rc5 29.Bxe6 fxe6 30.Rd6 Rc4
Black is a pawn down and about to lose a second one, so this is a rook-and-pawn ending that is certainly not drawn
