Column Mate

 Canadian chess player Joe Don played poorly to let the below position even happen, but it is instructive nonetheless. 

I don't know if Column Mate is widely accepted in chess parlance or vernacular, but that is what happened to Joe this Wednesday night in the USA. Mr Maple Leaf attacked the Black Rook at c6 not realizing his blunder setup a mate in 2 owing to the f3 pawn controlling the g2 escape square.

So, by now, you all see why a simple Queen Sacrifice Forces Joe to tip over his King. Also observe that the Canadian only had his Rook to guard the mating g2 square, BUT that occupied a vital escape square for the entombed White Monarch. 

I am guessing Miss Jessica Era Martin, chess instructor par excellence, would know the name of this mating pattern.
