why would you have three knights? Have you ever been in this situation?
Yes I have . I did it on purpose to "torture" an opponent who refused to resign in a hopeless position.
Can 3 knights force mate

No but it is the exact number needed to change a light bulb
As others said, 3 knights endgames are virtually nonexistent because underpromoting to one is very rare, having your two knights alongside is also very rare

I tried to set up some random positions with 3 knights and let the computer analyze them and it seems it takes max 20 moves to set mate
Why would you need computer analysis for this? Just download the Lomonosov tablebases app on your smartphone or use the Nalimov tablebases online.

But if I had done that you would have asked why I didn't used computer analysis instead.
in automate the variant you do not need to underpromate

Sometimes you need to underpromote

But this doesn't seem to be a "forced mate"
You may ask yourself about why they would have three knights but I think learning it can be a useful tool in understanding the knights.
Absolutely 3 knights can force a mate as stated by many others stockfish and ending tablebases.
I wanted to point out in the Albin Countergambit: Lasker trap it is quite common to underpromote to a knight to get a check very early in the game. assuming you just accidentally took your opponent by surprise you have three knights at the very beginning of the game if some mediocre to poor play ensued you could very well end up with 3 knights at the end of the game. I would not imagine this to be common but if you play the Albin Countergambit ALOT then maybe it's even worthwhile having the forced mate as part of your repertoire. Just a thought.
Kf5 2. Kg7 (2. Kh7 Ne5 ) Ng6 3. Kf7 (2. Kg8 ) Nd6+ 4. Kg8 Kf6 5. Kh7 Nc3 6. Kh6 6... Nf4 (6... Nde4 7. Kh7 Kf7 8. Kh6 Nf4 9. Kh7 Nf6+ 10. Kh6 Ng6 11. Kg5 Nce4+ 12. Kh6 Ng4+ 13. Kh7 Nef6# ) 7. Kh7 Nf7 8. Kg8 Ng6 9. Kh7 Nd5 10. Kg8 Nde7+ 11. Kh7 Nf8# { Black mates }.
Here ya go

33 bishops can of course.
More than 50 moves unless opponent blunder (helpmate).
3 knights checkmate is possible but I think it's easier than the bishop and knight checkmate
You have to promote one of your pawns to knight
cuz you can checkmate in any corner unlike the bishop and knight mate when you have to drive the king to the corner matching your bishop
Can 32 bishops force mate?
Please stop. You are making me very angry.
