Thanks for this, it is really helpful to see comments in English instead of in
computer!

My engine finds the first part of this line -  after 1.64 seconds its PV starts
with Kg4 Bc6 h4 Bf3+ Kxf5 - but after 47. Bd5 Rc3 it has no idea how to
continue. What is the winning technique?

[D] 8/8/5p2/3B4/P4k1p/1Pr5/5PK1/8 w - - 0 8

It is thinking along the lines of Bc4 h3+ Kh2 Kg4 a5 Rc2 Kg1 f5 a6 Rc1+ but the
score stops going up, indicating that it can't figure out how to progess.
