Black to move. How should Black proceed?
Bxc6 is a strong threat, but Black can successfully defend by perpetually attack the wB.
1. … Bf3! 2. Bf5 Bg4! 3. Bd3 Be2! 4. Bg6 Bh5! 5. Bc2 Bd1! etc.
If White ever captures the bB, Black will be stalemated.
2. Bb1/Bh7 can be answered by 2. … Be4! and from the b1-h7 diagonal the bB can always attack the wB.
We ought to ask: How did black get in this position in the first place!
Greetings,
White threatens 2. Bxf3, so
1… Ba4-Bc6!
The simplest antidote to the problem;
The theme to this position is as follows.
1.Black simply keeps in touch with c8-h3 diagonal ( preventing sac on h3)
2. Black keeps in touch with a8-h1 diagonal (preventing sac on f3)
3. Black keeps in touch with a6-f1 diagonal (preventing Bf1- Bg2 maneuver from white)
4. If White ever places Bishop on g4 intending Sacrifice on h3 or f3 then black Bishop must be on the a8-h1 diagonal in other to capture f3xBg4 ( In which black wins in that case)
5. If White flounders around with his Bishop Black must never make the mistake of playing Ba8 which would give white the Tempo to attack h3 or Maneuver to g2 but play along c8-a6 diagonal and d7-b5 diagonal.
6. If Black can’t be bothered to play around the c8-a6 or d7-b5 diagonals he can follow white’s bishop around but must not make the gross blunder of going ….Be4?? where White could exchange on e4 and wins.
7. Finally if White Kf2 moves to say e1 for whatever reason. Black plays …Kg1 and will remain there for Life.
To this end I declare this position Drawn
My Regards.
King.
Bf3 Bxf3
Bf3 Bxc6
Bxc6 Kd3
Kb8
this produces the stalemate with a couple possibilities.

King has done a great job (just reverse the colors or the board coordinates).
I don’t know what you think but my thinking process was a bit simpler:
White has 3 possible tricks:
1) Bishop sac on c6 or a6 and Bc8 (attacking b7 a second time).
2) If no “sparing moves” with his bishop, black is stalemate… white can’t take black’s bishop
3) White can’t move his king (Kd8 …Kb8)
With this in mind I think that black’s bishop just have to “go under white’s nose” with each move = go on the same diagonal h3-c8, h1-a8, f1-a6 proposing the exchange. White can’t take and its a draw.
Have a nice day
Black should just play g1/q+, winning.
Yes,white can do Bxc6 and b7+ and b8=Q++
1…Be1 loses because 2.Bd3 and Bxa6 and b7+,b8=q++
1…Bf3(if white takes is stalemate)2.Bd3 Be2(same) 3.Bf5 Bg4 4.Bb1(trap) and black moves on d1-h5 diagonal with the same ideas and it is drawn
I agree with Joshua!
I THINK THE bLACK SHOULD PLAY b7-b8+=q if the king take c6 than pin the bishop other wise protect the c6 pawn with the bishop.
I THINK THE bLACK SHOULD PLAY b7-b8+=q. Yes, but only if you allow pawns to go back…
