Do Capture History Updates In Probcut This patch introduces history updates to probcut. Standard depth - 3 bonus and maluses are given to the capture that caused fail high and previously searched captures, respectively. Similar to #5243, a negative history fill is applied to compensate for an increase in capture history average, thus improving the scaling of this patch.
