Opposite Color Bishop Endgames are NOT always a draw!!!!!!!!!!!

I dont think it's a mistake if it's intentional. Any move, except the bishop to g8, is a draw. The point was made that its not a forced mate, which is true. Nothing forcing about it. Just put the king on a white square and the game is over.
When humans want to express that opposite color bishop endgames always end in a draw, they will say "opposite color bishop endgames end in a draw".
When they actually say "opposite color bishop endgames ALWAYS end in a draw" they always mean "opposite color bishop endgames do NOT ALWAYS end in a draw".
One of the mysteries of natural language.

its not forced win its only a win it the opponent BLOCKS THEIR KING for some reason
so i think its a draw unless the opponent is a bit dum and lets you win
Two connected pawns often win. For example.
Yes the position you posted is won by white. But the following position is a draw:
So if you have two connected passed pawns and opposite coloured bishops you would definitely play it out until a clear result, win or draw, is happening.

Of course! I sure will. And also in normal opposite Bishops endgame with more pawns you can Always look if you can get two connected pawns even if you have to sac pawns that are only isolated and thus harmless. . Also passers that are far from eachother can win.

An example of a GM that lost ( today ) with an opposite collars bishops ending. And he is not stupid for sure. But maybe The Captian is just a much better player. Who knows!

It is all about the pawns.
Nothing is "ALWAYS", but generally speaking, if the stronger side can keep his pawns on the color of the defender's Bishop without losing them, and can continue to make progress, he usually wins. If the defending side is able to force the stronger side's pawns onto the color of the stronger side's Bishop, then he can build a blockade on the color complex of his own Bishop and draw.
Ofcourse opposite color bishop endgames are NOT always a draw.
That is NOT what you learn in theory.
What you do learn is that opposite color bishop endgames INCREASE the chances of draw when you are down one or two pawns, sometimes even if you are down three pawns.
