Commit ID 67f88f5e3e4ee6e4b49151173c2898253178506f

Return static eval when reaching MAX_PLY Makes more sense than returning a draw score. Tested with reduced MAX_PLY = 30 and passed both short TC LLR: 2.95 (-2.94,2.94) [-1.50,4.50] Total: 17434 W: 3345 L: 3194 D: 10895 And long TC LLR: 2.97 (-2.94,2.94) [0.00,6.00] Total: 2610 W: 488 L: 373 D: 1749 With current limit of MAX_PLY = 100 the patch should not introduce any measurable change, nevertheless is the correct approach. Idea of returning eval is from Michel Van den Bergh. bench: 8430785
