No, I am not asking if a KNN vs. K can be forced if those are all that's on the board. It is well known that this is impossible.
(I wasn't quite sure om if I should have put this in here or in the Puzzling Stack Exchange, do I chose here due to their being an actual chess viewer here. I apologize in advance if my decision was wrong.)
Basically, we've all seen those puzzles where no matter what defense one side employs, they will always end up checkmated in a certain amount of moves or something.
What I'm asking here, is if anyone could make a puzzle like this, of some sort but the end result is a KNN vs. K checkmate. I would prefer if these were the only materials left in the board. Only include other material if you must. Try to keep it to a minimum though, pretty please.
Now, if there is already a puzzle if this sort, please to leave a link to it in an answer.
Here's a small composition I made, not a puzzle but a game in which Black plays terribly in an obviously winning scenario, to give an idea of what I wish to see:
[FEN "Q6b/8/4q3/1NN5/8/7r/3KN3/1k6 w - - 0 1"] 1. Qa1+ Kxa1 2. Kc2 Rc3+ 3. Nexc3 Bxc3 4. Nxc3 Qb3+ 5. Nxb3#
