Retire Rml full PV search at depth == 1 Now that Rml ordering is based on normal MovePicker logic, apart for the ttMove that is given, we can avoid to score all the root moves at depth 1. We only need it for easy move detection logic, but in this case we just need to score the first two best moves and not all the Rml set.
