My dev version of Stockfish running on a i7-3970X @ 3.5GHz took about 10 minutes to see this line.
Looks like a search of at least 35 plies is necessary.

The Rf1 line brings about defeat much more quickly. Play it out a few moves and you'll see it is much more direct.

The pawn pushes (g4, g5) also seems to give the engines trouble.

Analyze

1q3k2/5p1b/5B1p/3pPPP1/1p1p4/1PbP1Q1P/r7/5RK1 b - -

versus this

q7/5p1k/5Bpp/4Pb2/1p1pNP2/rPbP1Q1P/6PK/1R6 b - -

Both positions are at move 44. The main line of play (second position), is way less forcing.

No. Here's the latest Stockfish finding the line at depth 32 in about 4 minutes:

Interesting that Boquet chose Critter's original line after a longer think time:
