I just checked my old sources and found that the KRNKR code has been there ever since the pre-historic (and pre-release) version 0.2.4. Nothing has changed since then. I have seen lots of KRNKR, KRBKR, KRKB and KRKN endgames during the last half year, but I never saw any problems. If you really observed a +4 score in KRNKR, it must have been a bug, but apparently a very rare one. It definitly does not occur except in a very tiny fraction of the possible KRNKR endgames. Tord
