IMO, this position isn't really interesting. I found out that this kind of
blindness of my program had been produced by a forward cut at depth=1. If I
relieve this cut a bit, the problem will be solved.

I don't think that there are many programs having a problem with the position.

Anyway, thanks to you Howard, for drawing my attention to this.
