Graz Game One

Maja Ziobrowska (1633) - Spanton (1883)
U2000
Spanish Berlin
1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0-0 Nxe4 5.Re1!?
Stockfish15 prefers this to the traditional main move 5.d4. Komodo13.02 disagrees, although in both cases there is not much in it.
5...Nd6 6.Bxc6!?
This popular continuation. albeit a distant second to 6.Nxe5 in ChessBase's 2023 Mega database, is for quite some time called a mistake by the engines (their evaluation button turns red). That is probably going too far, but it is food for thought.
6...dxc6 7.Nxe5 Be7 8.d4 Nf5 9.c3 0-0
Now both sides have castled, how would you assess the opening?

White has more space in the centre, the marginally better pawn-structure and a strongly posted king's knight; Black has the bishop-pair. The engines reckon the position is equal.
10.Nd2 Be6 11.Ne4 Qd5!?
This has been played by a 2117 and a 1957, but is disliked by the engines. I believe their point is the queen looks active, but Black cannot exploit this and White has time to target the queen. The engines prefer 11...Re8, which has been played by a 2363 and a 2079.
12.b3 f6!? 13.Nd3
Black to play and lose

13...Qd7??
Avoiding the annoying fork at f4, but walking into a fatal one at c5.
14.Nec5 Qc8 15.Nxe6 Re8 16.Qg4 g6 17.Ndf4 Nh6 18.Qh3 Bf8 19.Bd2
Not 19.Nxf8?? Rxe1#
19...Nf5 20.Nxf8 Kxf8??
Not my day.
21.Qxh7 1-0
