Talk:Queen versus pawn endgame

Mistake?

There appears to be a mistake on this page. In the Traps section:

4... Kb1??

is a typical mistake, allowing

5. Kc4!! c1=Q

6. Kb3 Qb1

How can the queen move to b1 when the black king is on that square. I don't know what it should be though. Qd1 would be an obvious blunder (the white queen is on e2) so no. —Preceding unsigned comment added by 131.107.0.103 (talk) 22:05, 31 August 2009 (UTC)

It is my fault. That paragraph of the source is very confusing about what the lines are and I made the error. Thanks for fixing it. Bubba73 (talk), 00:30, 1 September 2009 (UTC)

Another mistake?

The second example is NOT a draw:

"White to move, draw (a rare exception because the white king blocks the queen)"

The white queen can move to G2 to trap the black king. The only thing black can do is advance the pawn, but the king can get there in time to take the pawn. Then it's king queen vs king for checkmate. — Preceding unsigned comment added by 68.50.15.151 (talk) 21:45, 4 July 2014 (UTC)

No, after 1.Qg2 c2 it is a draw. Bubba73 ^{You talkin' to me?} 19:53, 5 July 2014 (UTC)

Error?

In the second example in queen versus pawn, the picture's caption states that it is "white to move, draw," but does not Qg2 lead to a win for white? 199.111.179.212 (talk) 22:33, 27 April 2010 (UTC)

No, this is a rare case with the pawn on its sixth rank with the other side to move, when the queen can only draw. If 1. Qg2 then 1... c2 and it is a draw because the white king is too far away. Bubba73 ^{(You talkin' to me?)}, 22:42, 27 April 2010 (UTC)

Sorry, I was looking at board upside down. However, I further examined it, and I agree that it seems to be draw. I had not seen the stalemate opportunity. 199.111.179.212 (talk) 23:01, 27 April 2010 (UTC)

The general rule (with a few exceptions) is that a bishop pawn on its seventh rank protected by the king is a draw because the king can go into the corner and abandon the pawn, and if the queen captures the pawn it is stalemate, unless the other king is close enough. With a rook pawn, the queen can't force the king out the other side, so it is a different stalemate unless the king is close enough. Bubba73 ^{(You talkin' to me?)}, 01:03, 28 April 2010 (UTC)
