Do You? People can play every time control including correspondence time control and when computers get faster correspondence time control of today may be tournament time control of the future. >>If the discussion about it does not interest you then you can decide not to >>participate in the discussion but please do not destroy the discussion again and >>again by discussing about what people do not want to discuss and generating >>annoying noise. > >Speak for YOURSELF!

It does not tell me if Nxe4 is the best move or not the best move. You can say that it is an interesting option but it is no news because the poster of the post already gave Nxe4 as an interesting option and in order to get a pv you can give the computer to analyze the position after Nxe4 and you do not need to have 5-best mode and can only compare between the evaluation and the pv before Nxe4 and the evaluation and the evaluation and the pv after Nxe4. There may be problem with some programs that are root processors and their evaluation is dependent in the root position but when I try to see with movei how close movei is to finding the best move I simply compare evaluation before move x and evaluation after move x so I can see how much I need to change the evaluation in case that I want it to find the move.
