Crafty's adventurous king

Does somebody know whether there is some way to make Crafty be a bit more careful about its king? The following game features a common accident of Crafty's. A human player could be not able to calculate, several moves before, that 41...f5+! would be a winner, but we are used to think that such an adventurous king invites disaster.

I would try to play around with the evaluation options.
To tell crafty something like "evaluation kscale <value>" from the
commandline or in the crafty.rc should have some influence on the playing style.
Please have a look in the crafty documentation. There is a chapter called "Alphabetic Listing of Commands".
Especially "17. evaluation option <value>" seems to be of interest.
