Black to move. How should Black proceed?
Source: ChessToday.net
I’d say 1… Qd4 2. R-anywhere Qxf2, since black can’t cover g2 and g1. e.g. 1… Qd4 2. Rf1 Qxf2 0-1
Way too hard.
I would try
1. ….Qd4
2. Rf1 Qf2
And I don’t see a defense against both mate threats.
Maybe Qd4?
Rf8 followed by Nf4
Qd4, R anywhere, Qxf2 and mate on g1 or g2 cannot be prevented
Qd4 is really strong…
Rg6
Qd4 followed by Qf2
take advantage of the fact that the d1 rook can’t leave the 1st rank in order to get position and activity:
1 … Qd4
2 Rc1
(Rxd4 Rg1#)
Here black can simply take the rook … Nxc1 or:
2 … Qf2
3 Qh3 (to prevent mate on g2. 3 Rg1 simply looses to … Nxg1 etc.)
3 … Nf4
4 Qf1 Qh4
netting a pawn and getting all the play.
white can try to avoid the line with:
2 Qf7 threatening havoc on h7. but black simply plays
2 … Qd1#
there is 1 … Qg7 which wins in all lines (i think, could be wrong)
i really liked this approach except white has 2 Qg4 which seems to stifle black, though he still has mass threats against g1 after …Qxg4 2 fg4 Rg4 etc. this line may work after … R(8)g8 considering the trouble white has in playing the immediate Rc1 (Nxc1), and the e4 bishop is hanging, etc.
1 … Qg7 may be the right first move
that’s all i see right now. could not look at it on a board so, apologies for loose analysis
1… Rg6 looks good (with ideas Nf4 trapping queen and doubling rooks).
strike: “Here black can simply take the rook … Nxc1 or:”
from my previous comment — it’s just wrong
1. … Qg7 is defended by 2. Qg4
So:
1. … Qd4
2. R7c1 Qxf2
3. Qh3 Rg3!
4. Rf1 Nxc1
5. Rxf2 Rxh3
and white is a rook up
or
4. hxg3 Nxg3+
5. Qxg3 Qxg3
6. Rb2 Rg8
also wins for black.
Mate is threatened on the back rank.
1… Rg1+
but the g1 square is protected by the white rook on d1.
2 Rxg1
So first we must divert the rook from protecting g1.
1… Qd4
2 Rf1 Qxf2, etc.
x. … Qg7
i just saw the funniest sideline:
after (from my previous line):
1 … Qd4
2 Rc1
(Rxd4 Rg1#)
2 … Qf2
3 Qh3 (to prevent mate on g2. 3 Rg1 simply loses to … Nxg1 etc.)
black has the amazing resource:
3 … Rg3
this harasses the queen and can’t be easily met. first, the obvious:
4 hxg3 Nxg3+
5 Qxg3 Qxg3
then, there’s the clunky:
4 Qxg3 Nxg3………
then, there’s the positional:
4 Qf1 Rg1+
what a game
Q-d4 to deflect the rook then rook on G-file checkmates
after my previous line:
1 … Qd4
2 Rc1
(Rxd4 Rg1#)
2 … Qf2
3 Qh3 (to prevent mate on g2. 3 Rg1 simply loses to … Nxg1 etc.)

i overlooked:
4 Rf1 which is probably the most critical variation.
one continuation is:
4 … Rxh3
5 Rxf2 Ng3+
and the knight can’t be captured by hg3 because h pawn pinned by h3 rook
so, if:
6 Kg1 Nxe4
7 fe4 Be3
skewering the rook, and maintaining threats like R(8)g8, and Rxh2
if:
6 Kg2 Nxe4
7 Kxh3 Nxf2+
