Do you think that you cannot earn more than 20-30 elo if you find some tricks to make Rebel search something equivalent to one ply deeper at the same time(I say equivalent and it may be more than one ply with more prunng or less than one ply with more extensions). I do not say that it is an easy task but I think that there is a room for clearly more than 20-30 elo improvement by better search. > >However even if you have good chess knowledge there is space for an 150-200 elo >improvement, especially in the endgame. > >My best, > >Ed I agree that there is a room for significant improvement by better evaluation but I think that the same is the case for the search.
