Something here seems to be wrong.
Are you sure that shredder5 can get only to depth 6 after 42 seconds?
I see no way to see +6.71 at depth 6 unless the program is similiar to crafty
and even Crafty can avoid 40.a5 at bigger depthes and it takes crafty less than
a second to get bigger depthes on p200.
finding f5 without leaving it takes more time but only 11 seconds on p200 and
crafty wants to play f5 at depth 10 and at bigger depthes.
40.f5 is the only chance(I do not know if white can save the game but there is a
serious bug in shredder5 if it gets depth 6 on pIII600 after 42 seconds).
