I was only kidding.
But in the position I gave, it certainly appears at first glance that Black can control h8 (because White must first move his bishop).

That is indeed a remarkable position you put up there.White's bishop does NOT control the queening square(white plays up the board,not down,right?),but he still has a win.
Nice one! 🙂

Can't find a win in Ilywrin's position though 😕

I just looked back...I took the bait on that hook line and sinker...I was viewing white moving DOWN the board 🙄

Wow,the black king is stopped on c8 by the pawn on a6 and the bishop on d6,right?
Awesome!

No need to feel sorry for me,I don't mind that I couldn't find such a tricky solution 🙂

yup, Sir Lose...

Crazy is right. There are 2 moves here to consider: 1.Bb2 and 1.Be7
The rationale behind 1. Bb2 is that after the compelling 2. ... axb2 the endgame is reduced to a K-P ending, that is far more easy to analyze.

So, as Bb2 seems to be an awesomw move, it is the first move to consider... It leads to a simplification of the position. And so that qualifies as a "conceptual move".

Kudos Crazy!

My regards

Ah, yes this was a study by Mahatadze (not sure if it is spelled that way ?!)
1.Bb2! (1.Be7 d6!! 2.Bxd6 Kxh5 3.Bxa3 Kg6 4.Bb4 Kf7 5.a4 Ke6 6.a5 Kd7! 7.a6 Kc6 =)
1...Kxh5 2.Bxa3 Kg6 3. Bb4! Kf7 4.a4 Ke6/or 4...Ke8 5.a5 Kd8 6.a6 Kc8 7.Bd6 and wins/ 5.a5 Kd5 6.a6 Kc6 7.Ba5 and wins.
Interestingly Black loses because of the pawn at d7 (preventing the move 5...Kd7 🙁 )

This win is not forced... if the opposite king can control the queening square and the bishop is the opposite color of the queening square its a draw...it doesn't matter which file its on.... a,b,c etc....

the king just just go back and forth and nothing can happen expect u can stalemate him.... a knight instead of an opposite color bishop is better in these situations...since it can control all the squares...

I beg to differ.I'm willing to play with a pawn on any file but the a and h file and a bishop of opposite color than the queening square vs a lone king,any day against anyone.I don't see how you can draw that....
Or didn't I understand you correct? 😕

It does matter as a matter of fact. Now just to free you of that illusion I will give an example:


White to move.White has many ways to win for example:
1.B~!! Kf7 (forced) 2.Kh7! and the pawn is promoted 🙂
or 1.Kg5!? (the Bishop defends the pawn) 1...Kf7 2.Kf5 Kg8 3.Kf6 Kh7 and 4.Kf7 + - or 1...Kh72.Kf6 Kg8 3.Ke7 and 4.Kf7 + -
The only wrong move here is 1.Kg6?? stalemate.
Knight is only more beneficial in cases of "a" and "h" files, and only when the pawn has not been moved to the seventh rank.

ahh i think this is waht i saw in the book..

pawn on g6, bishop on h7 and king somewhere...vs a black king on g7... the black king can go back and forth between g7 and h8... thats what i was talking about...

it works with a b6 pawn also...
