Tactics, anyone?
Saw that idea before, never knew it had a name, broken fianchetto. Loved your example with your OTB. Did you calculate that mate or did you just see the broken fianchetto pattern and play for it?

In the first place, if your proposed solution is less efficient than the optimum line, then it is not "correct" unless you are using a very odd definition of the word "correct".
In the second place: Enlighten us.
Show us how to make a puzzle that marks every possible winning move as correct while still rejecting any move that doesn't win. I wasn't aware than any such tool existed on this site.
Are you sure this isn't just bruised ego talking?
Blueemu. The poster has a point; namely many ways exist to win in chess. If I win someone's queen in one move, he will probably resign. But if I reject the win of a queen for a line, replete with three subvariations, and an in-between move which forces mate am I being efficient? The opponent might not resign in the second case because he doesn't see the win. Credit should be given for any move that in fact wins. Winning by mate or by material or by endgame technique is mostly style.

I find it a bit ridiculous to say that putting any old move in is a winning move, just because it is not a losing move, (because it had no effect on the game), so in this instance it seems that blueemu is correct.
I would rather only see the quickest solution to a problem, as having redundant moves in there wouldn't seem to increase my "ability to think tactically"

(I know that it is really easy)
