Who would have ever thought the man responsible for one of the most sordid incidents in the history of the Royal game would ever be thought of as a “good loser” by anyone at any time in the history of mankind. See: https://www.thesprucecrafts.com/what-was-toiletgate-611124

B12 Caro-Kann, advance variation
1.e4 c6 2.d4 d5 3.e5 c5 4.dxc5 e6 5.a3 (SF 9 at depth 45 plays this, expecting 5…Bxc5 6 Nf3; or 5 Nf3 Bxc5 6 a3. At a lower depth SF plays 5 Bd3 Nd7 6 Nf3) Bxc5 6.Qg4 (6 b4 and 6 Nf3 have been played far more often but for SF the game move is best) 6…Ne7 (At a lower depth SF goes with 6…Bf8 but going deeper prefers 6…Ne7 expecting 7 Nf3 Nbc6 to follow) 7.Nf3 (Komodo, at a lower depth, plays 7 b4 h5 8 Qxg7. SF plays the game move with 7…0-0 8 b4 to follow)
7…Qb6 (SF 151218 at depth 48 plays 7…0-0 8 b4 Bb6; SF 10 at depth 42 goes with 7…Ng6 8 Bd3 Bd7. Neither of these moves has as yet been attempted in practice, by a human or A.I.)
