Black to move. It is a very complicated position. What is the best way for Black to proceed here?

1 … g5 is the only idea that come to my mind. otherwise white eventually breaks through on 7th, 6th or 5th rank.

6th, 7th ot 8th rank. sorry
For me, at first glance, 1… Qf3 looks good, trading off the queen and threatening Qh1#. White must trade queens. If the white queen moves, then 2… Qh1+ is played anyway, followed by 3… Qh5#.

1… qf3 2. qxf3 r3xf3 3. raa7 +-

As mentioned by the first poster, White’s threat is placing his R on a7. 1…g5, which is mentioned above, discovers an attack on h6 by the black Q. White has to counter this (I think with Qh5) because Black would get a good attack on the White K by taking, with check, h6 on the following move.
I don’t like 1…Qf3 because after the trading of Q’s, White can play a7 or a8 and have enough time to mate the Black K before Black’s passed pawn can mean anything.
Yup. 1…g5 takes the sting out of the threat of Ra7 it opens a pathway for black queen to rush to the defense.

I agree.
1 … g5
2 Qh5 g4+! forcing the trade of pawns
3 Qxg4 Qxh6+ and black has the advantage.
1 Re7 RxR
2 PxR Qd8
3 Qxc7
After 1. … g5 2. Qh5 g4+, White can back off with Kg2. I’ve let Crafty work on it a bit (after I muddled around finding all the ways to obviously lose for both sides :P) and it seems that at that point, the best Black gets is a draw.
A lot of variations end up with one side having a Queen and the other 2 Rooks.
The threat of Qxe5+ is substantial since it pretty much always leads to mate in what I’ve run through.
I think the main idea here for white is both to stop black from playing Ra2-e7 with threat mates and create some kind of attack.
1……….g5
2. kg2!
and now if:
2……..Qxh6!?
loses to
3.Ra2-e7!
[in here white is threating to sacrifice his queen with : 4.Qxe6 QxQ 5.Rxh7 Kg8 6.Ra7-g7#; so then white must guard his e6, the question is how?3….Re8 loses to 4.Rxp+ QxP 5.RxQ+ KxR 6.Qh5+ K(moves) 6.QxR and white wins)
so black must play
4……Rf3
5.Qxe6 Rf3-Rf6 (not 5….Rf8-f6?? 6.Ra7-a8+ wins)
6.Rxp+ QxR+
7.RxQ KxR
with possible a draw….but i’m not sure, really.
After 1. … g5 2. Kg2 Qxh6 3. Raa7 Rdf3, the best either side can do is draw:
4. Rxh7+ Qxh7 5. Rxh7+ Kxh7 6. Qh5+ Kg7 7. Qxg5+ Kh7 8. Qh5+ Kg8 9. Qg6+ Kh8 10. Qh6+ Kg8 11. Qg6+
or
4. Qxf3 Rxf3 5. Kxf3 Qf8+ 6. Kg2 g4 7. Rxc6 Qf3+ 8. Kg1 Qd1+ 9. Kg2 Qf3+
But going back to 2. Kg2, that loses to Rd2: 2. … Rd2 (threatens mate after Qxf3+) and then Crafty has it playing out 3. Rxd2 cxd2 4. Qe2 Qd8 5. Rc8 Qxc8 6. Qxd2 Qd8 7. Qc2 Qd4 8. g4 Rf6 9. Kg3 Rxh6 10. Qxc6 Qxb4
@gorckat
You’re absolutely right. I completely forgot that after 4….Re3-f3 white really can’t play5.Qxe6 since black plays Rxf2+ with mate to come. A complete oversight takes shape when you analyze these positions without a computer.
I’m glad that i was on the right track, though.
BTW I really enjoyed the refutation to my 2.Kg2! with the simple 2…..Rd2. A good lesson learn a lesson never forgotten 🙂
1 … Rd2
2 Rxd2 Pxd2
3 Qd1 Qxf2
