Touch Move - Check!

I help out with my son's elementary school chess club, so I'm witness to many...um, interesting moves.  A couple weeks ago, someone picked up his queen, moved it to a square attacking his opponent's king, and without letting go of the piece, said "Check!"

Then he realized it was a bad move and basically said "never mind," ending up moving the queen elsewhere.  Since he never let go of the piece, if he hadn't said "check" it would have been perfectly fine.  But since he said "check", it's more interesting.

What do you all think?  Is this a touch-move violation?  If a person says check, are they obligated to make a move that results in check?  (assuming it was not an accident, thinking it was check when it wasn't)

I don't know of any rule that would force him to move it to a place that gives check.

There isn't a rule that  you have to say check, and other than kids and beginners playing, it's not normally announced.

Read the rules ... how boring.....
