I dont understand why white even waited to take the black queen, as well as why the king didnt take the other pawn???

 So as not to settle for stalemate.


Honestly I don't know who is worse:  the person who asks a question that has been answered 20 times already... or the person who answers it!




This was a good chess workout but I did not quite understand some of the strategy.

In response to big_bald_n_beautiful : If Black takes the pawn when put in check, White will win the race to promote his remaining pawn, and Black is lost. By not taking the pawn and moving to b8, Black can at least try to force stalemate, knowing that, if he does promote his a-pawn immediately after White promotes his h-pawn, then Qh8xa1?? is stalemate. This is better than having no chance whatsoever!  If Black can force an exchange of queens at any point, then the game is drawn.


if the pawn was taken on b6, the White h pawn will go first all the way to the last rank without a problem, be promoted to a queen and prevent black from queening.

While moving those queens are for 'tempo' until everything is forced and avoid stalemate


i think it's high time that some mods start regulating on the comments "first!" - 99

everybody hates wading through that bullshit to get to a comment of substance.


A classic.  Remembered the theme from a long time ago, which helped.  But a real head scratcher.


Nice Puzzle. I'm confused as to the purpose of Qg8. Why not just move straight to e8?


guess what this its AWESOME!!!

why didn't the king take the pawn on b6 to begin with?

if black takes the pawn then whites h pawn will queen the move before blacks pawn just like in the puzzle... exept no chance for stalemate.  so black can't really queen its pawn.


Nice--so old and still so difficult!


I don't know why more people aren't concerned with how the king could have moved, unless I'm wrong.  It is Checkmate, right?  Right after blacks queen promotion white could have moved king out of his queens way, was wondering if anyone else sees this.

And it seems like white played a horrible endgame which ends in a stalemate.


very incorrect puzzle

In commentary 40 you have a sharp analysis. The underlying ideas are:

1. White obviously wants to crown the h pawn not the b one. So you have to choose where you want blacks pawn to be crowned, in a1 or b1. By 1.b6+ you block the b column and oblige black to crown in a1. All is automatical till both pawns are crowned. As somebody said, h8=B is a drawn position because bishop can't attack black pawn in b7 since it's a white square.

2. Black king is wisely in b8, so white Q can't go over to the a column with a check. White would prefer black K to be in a8, but needs to check black in b8

3. White has a direct threat. If he received a check from black, moving wK to the 7th row would checkmate black. This is true except if bQ checks in d6 and wK in d8 can't place 7th row checkmating. 

4. So the ideal movement for white is Qe8 but that gives black another defense. bQ to g7 also forbids wK to the 7th row so wQ has to move to Qf8 or Qg8 first in order to held control of g7. As Qf8 allows bQ check in d6, the only remaining choice is Qg8

5. After bQa2, the desirable Qe8 is possible because bQ can't apply the defense of the 7th row since f7 is controlled by wQ.

6. Why Qe8 is so desirable? As said in 2), white want's bK in a column and has to check it in diagonal h2-b7. The problem is that wQ from h8, g8 and f8 checks obliges comeback to the 8th row in a vertical move to a square controlled by bQ while Qe8-e5+ allows two comebacks, Qe5-e8 and Qe5-h8 and bQ can't control both. BTW, bQ in a4 can't apply the defense in 7th row since d7 is controlled by the wK.

7. And now white has two menaces. The original wK-row7 checkmate after bQ check, and destroying the bQ defense in the a column since after bK move to a8 allows wQ to take bQ with a check and there is not stalemate.

Beautiful problem with many concepts appliable to endgames and thanks to the sound commentary #40.

there are multiple solutions, some of the moves are not forced

Very true. Good puzzle though.


There was a lot of unnecessary travel after the king transfer.

Can someone explain why you wouldn't have 7. Qxa1?

Because of this my good friend:
