FACED a German.

Sicilian Bb5(+)
1.e4 c5 2.Nf3 Nc6 3.Bb5 d6 4.d4 cxd4 5.Qxd4 Qa5+!?
The mainline in Chessbase's 2024 Mega database runs 5...Bd7 6.Bxc6 Bxc6 7.Nc3 Nf6 8.Bg5 e6 9.0-0-0 Be7 10.Rhe1 0-0 with a sharp position that Stockfish16 and Komodo14.1 reckon gives equal chances.
6.Nc3 Qxb5!? 7.Nxb5 Nxd4 8.Nfxd4 Kd8 9.Bd2
The chief continuation in Mega24 is 9.c4.
9...Bd7

10.0-0-0??
White has a slight edge after 10.a4, according to the engines.
10...e5 11.Nf3?
It was only after picking up this knight that I realised the problem with my position.
11...Bxb5 (0-1, 27 moves).
