After recently beating Fabio Caruana the Play Magnus App has been updated with "Age 28". Lets see what happens if we pit it against Leela Chess Zero. It makes for an interesting game, where Leela (playing white) slowly constricts black.

Black resigned because White's attack is too great. For example in a few variations White can take the Bishop on b5 with the Rook and play Qf8+ which is unstoppable.
