Rabid Queen only

I think in this position it was Black's turn but your diagram above says "White to move".

What does "depth 180" mean in your search output?

Yes but I posted the bad color to move too
May be the depth output in Skipper is équivalent to depth *= 20 ?

Copy this:

***********************************************
[d] 1r6/5p1k/2pq2p1/6Rp/3p3Q/4n3/8/4K3 b - - 0 1
***********************************************

But remember move/ply count not right.

after 52.Ke1 :
[d]1r6/5p1k/2pq2p1/6Rp/3p3Q/4n3/8/4K3 w - - 0 1
Isa play 53 .... Qb4!+ , force 53 Kf2
then It play 54 .... Ng4+ and white lose his Queen or is checkmate

What is a "rabid queen"?

So I think Skipper's move 52 ... Rb2 was a bug
