In the book's Chigorin Defence Stockfish lost all 3 games with black, #38, #138 and #238, by playing the sacrifical 4...Na5?!.
ShashChess as black played the main 4...Ne5, drawing 2 and losing 1.

The weird Vienna Stenitz Gambit saw 5 draws, with only SC-Capablanca winning - as black.
SC-Capablanca played the stunning 21...Rxe3 22.Kxe3 Qe7+ 23.Kd2 f5 24.Qe3 Ne5 25.Kc1. Later white moved its a1-rook for the 1st time in the game with 48.Ra1-h1.
(At 2 minutes, 8 threads, Crystal 200507 had 21...Rxe3 (black +0.56) also, but Komodo 13.3 had 21...Bxc3 (eh?, +0.57).)
2k1r2r/1bpq2pp/p4pn1/1p1P4/1b1Q4/2N1B3/1PP1BKPP/R2R4 b - - 1 21

Apparently Stockfish missed a chances to draw, both with Syzygy 6, Crystal and Komodo have 58.Re8+, 0.00, also 60.Rbe8+ 0.00 at 6 minuets, possibly others.
A difficult white R-pair vs. R+B+2 pawns ending - SC-Capablanca living up to its namesake.
