user23297: In a blitz game between Leela zero and Komodo, the following position came up.
[title "Leela Zero vs Komodo"]
[fen "8/8/2p3k1/4bpp1/2P3P1/4BK1P/5P2/8 w - - 0 1"]

With White to move. Or WHITE King on f3 Bishop on e3 pawns on c4 f2 g4 h3 BLACK King on g6 Bishop on e5 pawns on c6 f5 g5. WHITE to move.
The game ended with a draw, although at a certain point both engines gave quite a high evaluation score. We know Leela is notoriously weak in the endgame. Did Leela zero miss something? What happens with perfect play?
