2 openings same color won:
white, Rd. 8: E12 Queen's Indian, Petrosian, 4...c5 5.d5 Ba6
white, Rd. 48: B19 Caro-Kann, Classical, 7.Nf3 Nf6.
Stockfish only won 1 game 'on its own', that Lc0 did not win with the same color in the reversed, vs. Lc0's 6.


Lc0 played an amazing queen for bishop, knight and pawn sacrifice starting with 24.Bxd4!!?.
It did not recover any of its material until 65...Rxh5 sacrificing the exchange, but the resign score ended it.

Lc0 played a pawn sacrifice 14.d5, then added an exchange sacrifice 23.Rd6.
At the end it won still down both, though black had gotten its 'h' rook trapped.

The same opening colors reversed:
Lc0's worst error. Stockfish at 2' had 17...O-O instead of 17...exf5??
