One piece sacrifice by Leela at move 12. (she gains material back in 50 ply later)
AB engines do pseudo sacrifice, it means they always see material or other advantage back within their depth. However , Leela play with risks(winning probability), I am pretty sure that her MCTS wount see she would gain back a piece in next 25 moves, depth 50.

SF finds 12.gh6 quickly and with an advantage.
It has more trouble finding 9.g4 and 10.Rg1 - but I don't know if those moves are best.

After seeing the piece sacrifice of lc0 I think its level of play is not far from Alphazero's.
And another g4, this time 11.g4 against Stockfish 9 at 5 minutes plus 3 sec.
Stockfish 9 with three logical cores of the i7 4790S, which allows calculating about 3.86 million nodes per second against 3300 of lc0 (GTX 1060 3Gb), with a ratio of:
LeR = 3300 * 875/3860000 = 0.75
Stockfish 9 played with opening book perfect2018 without tablebases and lc0 11261 without opening book but with syzygy of 6 pieces.

In the following game against Stockfish 9, sacrifice of pawn followed by sacrifice of queen by lc0 11261, queen by rook and bishop, which has as compensation the devastating entry into action of rooks and pair of bishops.
Played at 25 minutes plus 10 secs, same hardware as above message LeR = 3300 * 875/3860000 = 0.75.

In the match AlphaZero-Stockfish 8, several positions of zugzwang appeared where lc0 paralyzed the rival.
The following zugzwang position has appeared in one of my tests. Played at 25 minutes plus 10 secs, same hardware as above messages but 6 logical cores LeR = 3300 * 875/6640000 = 0.43.
White moves.
