notes
1
	Black has a forced win with  …Rg6 +, and white is mated in at most 3 moves
	white can delay the mate by blocking with Bishop and Queen
2
	with White to move two possible moves are Qh5 and after …Rg6+ then Qxg6
	more likely is f3 …Qxe3+ , Qxe3 …Rxe3
3
	When you see the major pieces line up then start thinking about pins and skewers
4
	this lining up can be either how a Rook moves, or how a Bishop moves
	possibilities are : b3, g4 being the forking moves
	if g4 then black can save the piece by …Re5+ - King moves and then the Knight runs away too
	note that if the Knight on h5 is a Bishop then that doesn't work and has to be threatened or prepared with f3 or h3
	White also has the chance of skewering the Rook with Bc8+
