[d]r1bq3r/1p2b1pp/p1n5/3pNkN1/P2p4/8/1PP2PPP/R1BQR1K1 w
A silly position, mate in 1 to white.
My engine gives this kind of position a very high positional score +20.00 or similar, from king attacks mainly. What about yours?
Positional evaluation of your engine on this?

My engine fails. Not enought weight for King in Center Black I guess. [But first thing to fix is (idiotic) precision in numbers presented]

Weiss gives 2.93 - No way to pull apart the eval at this time
@xr_a_y printing the phase twice is a bit redundant
