Piercing Pins: Mate-in-one

Piercing Pins: Mate-in-one, by Ms Jessica Era Martin (aka BoundingOwl)

Time to pin it and win it!  In these puzzles first you will identify the pin, then be a bad sport, point and laugh at it, then make checkmate!  You can point and laugh at your computer screen all day, but please don't do it to your real live opponent. Watch the videos first!  Do the other puzzles second! 

A pin is a great tactic;  it's like you get to be the teacher and say FREEZE!  Then you stop space and time.   And then you morph into a transformer-thing and start checkmating.  Meanwhile the other guy is still frozen in a block of custard-flavoured ice!
