K&Q vs. K&R
Sort:
I think king and queen should win most of the time, I'm sure there are a few exceptions, but it is a very difficult ending to win.
King and queen will win as it can fork better than the rook and it has more influence Thats why the queen is worth more in points 0_o

yes but if the king and rook are next to each other maybe in the middle of the board the queen probably wont be able to fork them. So would that be a draw? or can the queen force them to separate and win the rook.
I hvae seen the diagram below in a book somewhere i believe this is how it works if I remember correctly, and there are some other veriations but this is winning for white. So back to my original question, does K&Q always win against K&R or is this just a special case?

Tis a good book this be true. I also spent a silly amount of time trying to beat a computer with K+Q against K+R, there was more chance of me turning metal into gold, and then the gold into a human boy.

Mueller has created some decent endgame training DVD's which cover the R vs Q ending.
If you are the player with the R you need to keep the king and the rook in the centre.
If you have the queen you want to move the enemy king to a corner or near the edge of the board so you can force the enemy to have to move their rook away from the kings defence. At this stage the queen moves in with checks until she forks the rook or mates the king.

no. you put the rook on the 3rd rank, and the king to d1 or e1. the 3rd rank defense is the best defense, but Q vs R is always won for the attacker. the 3rd rank defense can be broken with a correctly timed Qf5 or Qc5 (and pretty much nothing else), which forces the rook to next best defense, the 2nd rank defense. which in turn can be broken by zugzwanging the rook so that it's forced to abandon its king or the defender drifts into philidor's position (which is a mate in a few moves, and not to be confused with the draw). if the rook abandons the king, it drops after a series of checks and/or some typical non-checking moves which prevent the rook from re-uniting with the king.
here's a typical example of breaking the 3rd rank defense that I just blitzed against fritz:
since the queen can threaten diaganol, unlike the rook, she can fork the king and rook in some way. So, in order for the K&R to win, there would have to be some special circumstance where the rook puts the king in check, and by moving the king exposes but can't protect the queen (a skewer where the king is at least three squares away).
does king & queen always win against king & rook, or only in certain positions? And hopefully someone can provide examples.
thanks.
