Very true but a great puzzle nevertheless.


Where is Rc3 a possibility?


On the 10th move. I believe this solution works around that kink.

 

 

 


10... Rc3+ 11KxB, then ther is nothing to prevent K or Q from entering b3.

bondiggity

Actually there is. The rook blocks the king from the 3rd rank, so yeah the queen can now freely enter b3, but that will have no effect since black can just capture the queen. 

MetalK

actually this mate is forced.. as surprising as it seems.  the queen keeps the rook off of c3 if the rook goes to c3, the point is the queen will take it, with mate on the next move.

btw.  black can prolong the mate by marching the pawn on h7 down to h1 before the h2 pawn queens.  otherwise,  excellent

Please stop being ignorant and read what I have posted. Obviously you can't play Rc3 when the queen is on d2. The thing is the posted messed up the problem and on the tenth move with Qe2?? gives the game to black. If you look at my earlier post, I clearly show that this is a forced mate, but it can be done in 97 moves.

The rook can't stay on the 3rd rank, it must come back to bloc k the checks

How about instead of posting hypotheticals you post an actual line. Play it out and you'll see that that it is a win for black. Or if you can't I'll gladly refute any line you post that argues that white can win after 10...Rc3+ 11. Kxa4

fair enough i misread your quote earlier, but you are wrong.  the solution is more than 97.  black can prolong it b/c the pawn on h7 can move 7 times (as long as the pawn stays on h1).  i agree Qe2 is completely wrong it allows the king out of the corner, an obvious mistake.  and i also agree that there are many pointless moves that leave to the same position.

True. I was just sort of following the originally posted solution and tweaking it. I forgot that the h-pawn could be used to delay for a longer period of time. The same could be said for the original problem. 

 

Sorry for my outburst, I was just getting a little frustrated @ the poster saying that I'm wrong when clearly Qe2??  is a mistake. 

MetalK

i understand.  to be clear Qe2 is a definite mistake.

if black base is in the bottom.. then mate in 2. If not, b to c2 will free up the black king.. eventually.

I see people posting Mates in 10, or 12 moves. well, here's the granddaddy of them all...


 bingo... i did it

Some moves are repeated for no reason. The first is that after Qxd3 the puzzle then forces you to go back to d1 then d3 before Qf1!. This could be played straight away and would shorten the mate.

Other than the fact that the h7 pawn can prolong the mate I think bondiggity is spot on with all of his analysis.  :)  And some might ask why not block the threat of Qb2# with Bc2 everytime the white queen goes to d2.  But then white plays Qc3 (black no longer protects that square) and black cannot prevent Qb2#.  :)

 

It is a good puzzle.  :)

What if 90 ... Bc6? Then there will be virtually no way for white to win... White can't check at Qb4 because of the pawn on a5, and black can simply promote the pawn since it is protected. If white checks on e1, then black can block with the rook and there'll be no way for white to check again.

bigfish

nice

bondiggity

Yes, this would probably be optimal.

Here is 90...Bc6  :)

This reminds me of those pool trick shots where they set up a completely contrived, impossible situation and hit the ball and the result takes 5 minutes
