Deep fritz also likes this move but never stops crying for many minutes
-- means that Deep Fritz cries and Deep fritz is crying for more than 20 minutes
on my pIII800.

Finally Deep Fritz stopped to cry and you can see Bh6 without the -- sign
but I am afraid that it is only a temporary feeling and Fritz needs a babysitter
to help it not to cry))
The best way seems to be simply to give it another position.
