Originally posted by torspoheh, I've done that a number of times. I would say for beginners it's the knight. For me, it's the queen, but it's usually cases where there is a revealed attack leading to a double attack by the queen 1 to 2 moves later.
I would say rooks are most problematic. If I have a choice which rook goes to open file, I always end up moving the rook that doesn't belong there.
For me it is the knight. But then again, I've not mastered any of them!
Knights give me more trouble than any other piece. They seemingly come out of no where and wreak havoc.
I have a tendency to leave my knights on defense, poor decision most of the time, but I really cant work that knight magic many of my opponents seem to create.
Studying up on them now at a site called predator at the chessboard. Excellent site btw...
