i dont think ive ever seen the use of a nite like that

Great puzzle and first page !!!

Not the hardest puzzle, if you recognise the basic mating patterns :)

first 

nice disruption tactic

Ha! Great block with the Knight.

I'm guessing the move that lead to this was ...Bb4.

Fun!

Big sacrifice for big payoff.

1st page

Great puzzle.  And second time on first page.

A good one.

There is actually some variation in the puzzle, but if black plays differently, it still leads to a mate in five or less.  This diagram shows why.

That was kinda fun, I wonder who figured that out.

bzzzzzzzzzzzzzzz

Great use of the Knight to "block" the Queen's access to the back rank where all the action is.  I'll have to remember that idea.  Thanks for the instructive puzzle.

Looks like a smothered, but its quite different, actually.

Very good puzzle- Thanks Jakesterb 127 for the analysis

Decent.
