Big difference in the evaluation between Stockfish 10 and Leela Chess Zero

[Javier Ros]

A little over a year ago, nobody in this forum would have thought that any program or human would frequently defeat Stockfish positionally over the board. Its analysis power leaves no doubt of its first place among the computer programs.
But the appearance of Alpha Zero and Leela Chess Zero has changed things.

In the next game, the great disparity in the evaluation between Stockfish 10 and Leela Chess Zero shows the difference between the approaches of both.
Lc0 32374 played on RTX2070 and Sf10 on i7 4790S 6 cores, with 5 minutes plus 1 second per move.

This is the second position of the Balsa 25 Top Set, with thousands of games played between the best human players

the initial evaluations show the equality of the the game: 6. e4 {0.35/13 6} Bb4 {0.36/27 20} 7. Nxc6 {0.31/13 3}

then 7... dxc6 {0.29/28 5} by Sf and Lc0 thinks to have some advantage 8. Qxd8+ {0.80/14 5}

after 13.h5 {0.84/11 13} Bb7 {0.00/26 5} 13... h6 was better to avoid 14.h6
