Hello Uri,
In ChessMaster a + score is good for white so an increasing + score is even
better for white.  I gave the position to Rebel Century 3.0 on my Athlon 900 and
it finds Rd5+ after only 16 seconds but changes to Rb4 at 28 seconds.  Then it
switches back to Rd5+ after 1:06 and keeps it past 6:45 and 12 plies with a
score of 0.91.  I guess it will stick with it.
Jim
