d5, d4 vs. d4, d5, c4. Through efficient lock-free multi-threading the cache can double nodes per second (NPS) after a short time at the start position and reach even higher numbers in simpler positions. While this can give slightly incorrect value and policy when move ordering does make a difference, the speed gain compensates by allowing additional deeper evaluations.</p>
