Very interesting endgame. However, it has been my observations that engine do not play these endgames well , and this seems to be another case. I will analyse it myself, then use and engine. Looks better for black, but white may be able to draw. This is my conclusion with a 5 min glance, more time will be need to fire up these neurons (they are suffering 12 year old scotch).

.

The misspelling was deliberate as that's the way you pronounce gigawatt. It had a time when spelling it like this was humorous, but I guess it's time is gone :)

Corrected grammar, the scotch, the fingers, scotch crossed mind.

My first guess would be a bug, but we never know with today's engines.

I'm running the line Re8xe3 Qd2xe3 Qd6xa3 on my outdated hardware right now (if the position is loosing for black after Re8xe3 Qd2xe3, so must it be after the further Qd6xa3):

[d]5rk1/5p1p/6p1/p2P1bP1/2p5/q1P1Q3/6BP/4R1K1 w - - 0 1

At depth 22, FireBird 1.01 currently reports (with white to move):

00:09:15.1 -0,61 22 265884573 Qd4 a4 d6 Be6 Bc6 Rd8 d7 Qe7 h4 a3 Re2 Rb8 Kf2 Qd8 Kg3 Rb1 Qd6 Ra1 Qd4 Rf1 Qa7
