Small simplification in probCut movepicker Remove no longer required condition for tt moves. The idea is that if tt the value is greater than probCut beta try tt move that is a capture anyway - even if it doesn't pass SEE check. This idea in various implementations passed some STCs and was looking decent at LTCs as a gainer.
