Well, GM Spielmann was correct. In the 30's he enunciated an idea that in general 2R+N is equal to R+2B. Of course it all depends on the position, but I wanted to test this out so I took Knut Neven's great 1,300,000 game database ( very low double ratio) and did 2 searches in ChessBase to test Spielmann's theory. I searched using the search on materiel feature only in Chessbase 6. The first search had white with the 2 rooks and the second search had white with the 2 bishops. The first statistic was 56% score for white and in the 2nd case, it was 55 %. This shows that Spielmann was correct. So what do we conclude from this? Simply that if you are in a position where you have a chance to get into this materiel balance, don't be afraid to play it from either side, all else being equal. Please note that from the classical point count rule the 2R+N =13 points and 2B + R =11 points, so that a priori, one would think that the 2R+N is much better. Such is not the case as Spielmann pointed out. --
