I also wrote a special KRPKR evaluation function recently, and it has turned out to be useful surprisingly often. It is probably useful even more often than I notice, because there are probably often important variations with this endgame even in games where the endgame never appears on the board. As you say, writing a reasonably good KRPKR eval isn't all that hard. It's a good idea to write some code for this endgame even if you always plan to use the full 5-piece tablebases, because it enables you to see wins or draws several plies earlier. Tablebases are great, but they shouldn't be used as a replacement for endgame knowledge in the evaluation function. Tord
