A test position from the european under 18 championship

Post by Uri Blass »

[D]8/4nk2/1p3p2/1r1p2pp/1P1R1N1P/6P1/3KPP2/8 w - - 0 1 bm Nd3


Note that you need Nd3 to win the black rook later otherwise black has the idea Nc6 with Rxb4 next move.

Seems rather slow for 48 threads, but I know nothing about Zappa Mexico. Does the engine have any UCI options related to its parallel search? (For example, something like Minimum Split Depth?) If so, you may want to modify the default values to see if you can improve the search speed.
