Queen Check!

It's a Canadian thang. 

Actually, a teacher friend of mine, born and raised in Canada, told me that at his chess club in Canada, if one did not announce "Queen Check!" loud and clear, that person got beat up and tossed out!

Now don't get offended. I am not suggesting that everyone in Cananda is shouting "Queen Check!". I only know of one club where it is required.

My idea of a Queen Check -  A tactical motif, one where the queen is attacked, accompanied with a discovered attack on another piece. So, it's basically a type of double attack, where both pieces can't be saved with one turn.

I had an OTB opponent who wrote QC on his scoresheet when a queen was under attack. It still strikes me as odd, but I've seen far odder. Young players who have just begun the game but who have learned a few tidbits from weak players who have no exposure to tournament chess and official rules often tell me, "if you do not say check, the king is not obligated to move out."

Then, you see in the forums here the frequent question, whether a piece pinned against a king can still deliver check to the other king (or protect a piece that is checking). 

A piece, still on the board, which can no longer check the enemy king? Never heard that one. Dang!
