Cfish 280920 64 POPCNT NUMA + nn-baeb9ef2d183.nnue thinks between depth 40 and 50 that h7 is 0.00 or +50.00.
And the Engine eval. is jumping all the time.

Is the position after h7 won or only a draw?
Is this a good test position for Engines?
I never saw a Fish jumping that extremely between 0.00 and a clear win on different high depths.
I hope that the developers can improve the Fish.

this is win position for white
