Is there a possibility of a 0-1 result demonstrating the power of the black queen? 

I saw some perpetual check, but no win, but i'm not very strong

In my opinion Black can still win. After 1...Qxb3 2 Rxh7  Qc3 forking White's king and rook. After that Black will certainly not lose.. and I think Black will manage a win due too the queens power.

It would be impossible for black to win with just a Queen here because mating is impossible (unless white intentionally helped black mate him.) 

I think its a draw after the R K fork that shinrikyo pointed out.

it depends who's turn it is if its white's they win but if its black there is a possibility that there will be a draw

 

After the fork, it's an immediate draw by perpetual check, I think.  If Black doesn't accept the perpetual White's able to promote.  There are a bunch of possibilities, and I didn't spend much time looking at them.  This is just a first look sort of thing.

 

After 5.Bc5+ can you play Kf6 and run with the king?

After  1...Qxb3 2 Rxh7  Qc2ch 3.Kf1  QxR 4.Bf4 dont see how black even draws. If white king gets to G2 is safe from checks, and otherwise how is c pawn stopped from queening. Black might have to try 3... Qxp instead, and hope when f pawn advances will get perputal check. This seems very unlikely, so I agree with King William that white is winning.

Hello again,

Think earlier posters  4Bd7ch is mistake because firstly it is black fighting for a draw, only white has winning chances, and secondly bishop sits nicely on g4, stopping blacks attempts for perpetual check. For example, after 4,Bf4 Qd3ch 5Kg2Qc4 6c7 wins

Ah, yes.  4.Bf4 is much better!  Thanks!

Thats all well and good if black plays helpmate however It would be a draw because black wouldn't play Qc2+. 

At first glance I see a queen vs 2 bishops in the ending.  the play would go ...Qxb3, Rxh7 Qc2+, Bd2 Qxh7, Bd7+ Kd8, Ba5+ Ke7,Bc7 and i'm not sure how Black can proceed from this point.  The problem is that c-pawn.  If white queens it, and I think it's possible, then this should be a lost game for black.  This is a position that you'd have to ask a computer to analyse.

Thanks all for the analysis.  In De-Lar's move list, I think white helps the draw, I have come up with a move list where white wins, but move 16 by black is probably a mistake.  I would however agree that with correct play by black, it would be a draw.

 

Hello,

 Yes I lived up to my nickname, had overlooked Qb5ch. But trying desperately to still play for win, how about 7Ka6 with idea 7...Qd3ch 8Kb7 Qb5ch 9.Bb6. 

Bye John S 

What if White tries 7 Ka6 in this line, can Black prevent the promotion?

I think white is winning this two bishops and pawns verus queen endgame, but have made mistake before, so not so cocky now

 I think here black would play Qc7 attacking the pawn and not Qd3ch.

How about if instead of taking the rook after the queen takes, white starts harassing the king with the bishops?

Starting with bishop checks will only result in giving black a winning position.  After the rook exchange it requires a very high level of accurate play by black to draw, which many of us will not be able to, resulting in white winning.  Is this example, black will pick up the white rook, if it does not exchange on move 2.
