Problem ID: 0040209
Ok, this is just annoying. 3. h8=Q is "uncorrect" but the solution is 3. h8=B.
Yes, h8Q is incorrect. The explanation is in the notes (which you can see by clicking on "View Analysis and Source"): h8Q? Kd2! and Qxa1 is stalemate.
But, Leo, if white promote a queen, they are not obliged to take the black qeen on a1?! White can continue for example with ...Qh2 Kc3; Qc7 and if:
1. ... Kd2 then Qc2 and mate; if
2. ... Kb2, 3 or 4, black don't have the save square d2 and I suppose you can take the black queen without a stalemate (will explore that later)
I promise you, there's no win there :) Tablebases (such as the one at http://www.k4it.de/index.php?topic=egtb ) confirm it.
Thanks, saved me few hours:) Nice tablebase!
Wasn't so obvious to me at a first glance
all you have to do to know it's B takes without even calculating is see the amount of time is terribly skewed for this problem and thus, it must not be the 'easy' solution.
You should always be on the look-out for stalemate attempts... h8=B+ is the clear move.
Underpromotion to a Bishop isn't vey common, is it?
Amazing one, Indeed
heh... there are only on solution in trainer. So Bishop it is! The other is stalemate.. Didnt even use time to look at the position.
Does anyone know if this is a composition?
somebody did mistake when he was creating this puzzle..because afther h8=Q black can play ...Kb4 Qxa1 ...Kc5 NO STALEMATE AFTHER Qxa1.. this puzzle should be reported because this is mistake
but it's h8=B isnt it?
curse you camembert. freaking camembert. oh you'll get yours. oh yeah you will...
There are so few instances in which promoting to a Bishop is called for.
wow missed the bishop promotion.
héhé Too quick I take A Queen But with the queen is a draw :(
Yaaay I'm one of the best =))
As I've said before, this sort of thing should be in a separate study section.
