Not a single correct answer so far.
Qb6 Qc4
Rc8 a5
Rxc5 axb6
Rxc1+ Bd1
Rxd1+
this one was hard for me to see. kept trying that Bxf2 line and couldnt see a mate.. there was always a way to have it got refuted.. i knew that the Qb6 was the line to play..
I think 1… Qb6!! is much better than Hugh Jarce’s 1… Qa7, as it covers the d8 square as well. The immediate threat is of course, 2… Qxf2 mate, so white needs to do something about it. Say:
2. Bxg3 Qg1+
3. Bf1 Nxg3 (threatening Qxf1 mate)
4. Qc4 Rac8!
and white’s goose is cooked. If the queen abandons f1, Qxf1 is mate and if it abandons c1, Rxc1 is mate. He can try 5. Qd3 blocking the d8 rook, but after 5… Rxc1+ 6. Kd2 Rxd3+ he has no hope left.
What are other second moves for white? One is:
2. Qc5 Rac8
3. Kf1 Rxc5
4. Bxc5 Qb7
and black is now a queen to the rook up.
1. … Qb6
2. Qc5 Rc8
if
3. Rd3
3. … Rxc5 and the black Queen protects Rd8
if
2. QxQ Rxc1+ with mate to follow in two.
if
2. BxB Qg1+
3. Bf1 NxBg3
4. Qc4 Rac8
1…Qb6! and now (a) 2.Bxg3 Qg1+ 3.Bf1 Nxg3 4.Qc4 Rac8 wins or (b) 2.Qc5 Rac8! 3.Qxb6 (3.Rd3 Rxc5 4.Rxd8+ Qxd8) Rxc1+ 4.Bd1 R1xd1+ 5.Ke2 R8d2#
1…BxB 2.KxB Qg3+ 3.Kf1 Rac8 if 4.QxR Ne3+ and Qxg2#. If the white queen leaves the control of e3 then comes a mate and otherwise the queen will be lost.
Black wins with Qb6 and after Qc5, with the zwischenzug Rac8.
Not too proud to admit that b6 is the square. Obviously, as pointed out, I failed to see that the Q needs to cover d8 as well. Thanks guys
Gee, I must be really dumb. I simply can’t see what happens after 1…Qb6+ 2. Qc5 Rac8 3. Q:b6 R:c1+ 4. R:c1. Black is just a Queen down here to me.
The best I can see is 1… Qa7+ 2. Qc5 Qd7 threatening to win the a-pawn and also to invade with Qc2+. But these are hardly decisive threats.
“Pra said…
1…Bx f2+ 2.Kxf2 Qg3+ 3.Kf1 Rac8 if 4.QxR Ne3+ and Qxg2#. If the white queen leaves the control of e3 then comes a mate and otherwise the queen will be lost.”

I agree…after 4…Rac8 if 5.Bc4 Rxc4 6.Qxc4 Ne3+ Black wins the Queen.

I simply can’t see what happens after 1…Qb6+ 2. Qc5 Rac8 3. Q:b6 R:c1+ 4. R:c1. Black is just a Queen down here to me.
After 3. … Rxc1+ whites remaining rook is on b3, and can’t capture on c1.
