Problem ID: 0038208
If you promote to a queen (or rook) then this will pin Black's bishop to his king and leave him with no legal moves. Since he isn't in check, that means it is stalemate and a draw. So White must promote to a knight to prevent this. He can take on c7 next move, after which it's quite easy to win.
and promoting to a bishop is useless
Why is this rated 148????
Why 400 indeed!
Lowest pass rate for a 400. All white's moves are forced up until the last one, so only the promotion and the mate should be included.
Definitely more difficult than 400! Thinking of which piece to promote the pawn into is definitely way beyond the realm of what a beginner should be concerned about, based on 2 facts:
- beginners rarely see any endgames at all, but the game will be decided much earlier
- even if you reach an endgame (also as an advanced player), for practical purposes, how many times did you have to NOT promote into a queen?
Such a low puzzle rating makes absolutely no sense.
pass rate of 7.1% but a rating of 400?!i think the beginners queened at the end, but still got points for a partially correct answer
Revisting this after 4 months and solving it rather quickly. Basically you have to recognize the stalemate / underpromote idea.
It is a most instructive puzzle, but the rating is still stuck at 400 which is just ridiculous.
