Commit ID 1b5738e0c958ac8d3d140a3d182b85f8c0c0cd2c

Simplify statScore initialization This patch simplifies initialization of statScore to "always set it up to 0" instead of setting it up to 0 two plies deeper. Reason for why it was done in previous way partially was because of LMR usage of previous statScore which was simplified long time ago so it makes sense to make in more simple there.
