Wrong bishop endgames

So you say.. I saw that at St. Louis Chess Club lectures. Jonathan said Fabi could do it in seconds but its extremely difficult for us mortals

And you need a solid plan and calculation how to stop Black king from reaching h8

If you did it without an engine, and of course if you 'actually' did it.. congratulations then.

But i highly doubt it since you might have missed a proper response for black and things might have gone easier.

I did without engine too. Whites promote,black king just have one move left, so no forced draw,so next Queen F1 and finnished if i didnt went wrong

Edit: i just saw black king has a bit of room to try to scape, but i wouldnt know why wouldnt you promote. If you dont, black king will force draw isnt it? Is it there any basic stuff am i not seeing maybe? The other option would be letting the black king to take out white bishop,there are still chances with Queen and King,but why to do it more complicated?

This is about promoting. Not letting the black King reach h8 was just a concept/talk. Your wording makes me believe you may not understand the solution. With best play, Black will capture the Bishop, the pawn will promote checking the King. The King then has 3 squares on the 7th rank to move to. If you came up with something different then yes, you missed something. pfren gave away a major clue, along with what I just added. Work it out, use an engine, post question here, or even message me if you like, if you have trouble seeing/understanding this.

@ExonArch I solved this, and checked it with the engine to confirm I did not miss anything. I will take the time to write down my thought process, which lead to the solution if you wish. Just ask.

Ok maybe its my english or maybe im too amateur, so just lets play,

My turn, i move and i do promote that pawn.  Isnt that the question?

Your turn, if you want to move. I dont see how not promoting that pawn can help given that whites moves first.  Unless im losing sth on the big picture, feel free to tell me so

edit:its not even about an  engine , i dont get how not promoting is any good on that game, based on logics , at first glance. I think i would hate that engine being a profesional. Like its all done and said. 

Yes it is about promoting, and yes white can promote. With best play you will lose your Bishop in the process, or the game will end in a draw. This is what I see. Shall we do this by message so as not to disrupt this thread? Your White and and it is your move (In this puzzle white moves first)

There is a 7 hour time difference between us, so I expect this to be lengthy. I will try to make my  moves as often as fast as I can. The rest of today and tonight I am very busy. 

OK ofc we can do it by private to dont disrupt the thread thats a good idea, i have no hurry, yes i promote that pawn to queen. If you try attack the bishop with your king i'd do next queen H1 to queen  g2 and i'd win unless im losing to see sth obvious. Thats why i dont get why good players you are questioning over sth i see too obvious, so probably im losing some forced draw you have room for if i promote? That woud be the only reason to dont promote if you have tried or engined all the possibilities

Yes with best play I will capture your bishop on e8. You will promote to a Queen on h8, Does not matter if the King moves to d,e, or f7. It is a simple mate for white. If this does not happen then  you are not playing best moves.  (I am not a good player, just do to many puzzles)

Bg2, easy, solved in seconds

Ok.. the solution is (as you already found it);

Here is the original lecture from Jonathan Schrantz, video contains another wrong bishop endgame exercise as well, thanks for participating

Lol i was loocking the square switched my bad bigD521.  Thats why we werent understanding each other,my bad. 

Anyway yeah with whites first whites protect the diagonal with the bishop and thats all. Btw and after having saw the ExonArch solution to that puzzle, honestly my first move wouldnt have been Bishop D7 but instead Bishop C8 (i need to learn the numbers still). as i'd feel that protects better the diagonal. And maybe thats a mistake you'd take profit of idk. And yeah pawn*2 to get over that white diagonal protected. Or*1 to do a match idk why but i feel doing matches constantly as well as its a protected piece its a good idea as the rival its not an engine but a human. 

Whatever i got the board wrong my bad. And thank you ExonArch post as much bishops end games as you want to,thats the piece i need to improve more and its just fun.
