The SF line 1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. O-O Nxe4 5. Re1 Nd6 6. Nxe5 Be7 7. Bf1 Nxe5 8. Rxe5 O-O 9. d4 Bf6 10. Re1 Re8 (or a transposition) was first played by Steinitz and Zukertort no less than in the 1886 World Chess Championship! Source: Encyclopedia of Chess Openings, Volume C, 5th Edition, 2006. This agrees with ChessGames database, where the position after 11. c3 Rxe1+ 12. Qe1 (SF differs with 11. Bf4) was not played for a century, from 1899 to 1999. This position was played again in the 2013 World Chess Championship.Nay Lin Tun wrote: ↑Sat Feb 06, 2021 10:29 am Berlin is Leela and A0 pet choice, but I recently noticed that SFNNUE also agreed.
