Here is the beauty that bishop and knight create in real game that can be easily miss in real condition over the board. A lot of players just don't appreciate enough what bishop and knight can do.

Should i learn the bishop and knight vs king checkmate?
Sort:
It is simple once you comprehend the example and obviously after you rehearse it.I would prescribe you to learn chess online. It is a decent case of knight and cleric collaboration.
Guys if you put the time discussing this into instead trying to learn the ending you'd have known it by now. Now that's what I call a waste of time!
I have been playing chess for over 20 years and not once have I had to execute a king, bishop and knight vs. king mate in any game I have played. That tells you something about how commonly it comes up.
So yeah, it's nice to know how to do it, but it's not something to lose sleep over.
Problem is, if you meet it even only once in an important game and you can't give it, you could have a bad night that day!
Well... I can win it blindfolded, but I have never met it OTB (the last 42 years, that is). It's useful, but not essential knowledge.

I'll be sure to let you know if that day ever comes!

For some it will never come even if they play chess for 100 years. For other it will come next month from now and then 3 weeks after that. I used to think it's almost impossible but it happened to me just 2-3 days after i learned it and i failed to deliver due to time trouble, basically premoving half of the moves
It hardly ever happens.
How can be a waste of time being able to win a won game?

If your time is limited and/or you're not very interested in endgame techniques, I'd say skip this endgame. It's doubtful that it will ever occur in one of your games, and if it does, the worst thing that can happen is that you draw what would have been a won game.
I happen to like practicing endgames, and I find this one to be fascinating. I randomly place the pieces and play against the computer. It's an entertaining way to pass the time.

It's impractical to learn how to win a won game in a position you might not see in your lifetime vs dedicating that time to something else.
There are other, alleged, benefits to learning this mate though, and I wouldn't someone from doing so.
Yes, but how many things will one miss on his/her chess carreer because of dedicating some hours per month to learn this?
The most effortless way is the chess coaching for adults as clarified by Averbakh yet I am not certain there is a youtube video on it.
I eventually got around to learning it for fun, but I don't expect to ever need it in practice. I learned en route that it's exceptionally trivial on a 4 x 4 board and easy on a 6 x 6, but harder on an 8 x 8 in view of the line where the defending King makes a break for the centre.
Following on from Ziggy_Zugzwang's excellent exposition, there's an alternative to 6. Ne7. 6. Bf2 also works and figuring out how to make it so is an amusing exercise in piece coordination. You can get the Knight to e3 and the Bishop to g3 just in time to corral the Black King and after that you have him in a box. I've played this line against tvchess often enough to get it working. It takes a few moves longer than 6. Ne7 though.

i think it is necessary. I just had a knight vs queen endgame, and couldn't convert for a win. Its not the same as a bishop and knight, but its the idea that these endgame drills need to be mastered.

Late to the party.
My two cents: learn every endgame/mate you can.
Wouldn't it be a shame to draw a winning endgame? Or lose a drawn endgame?
I think so.
And I agree that B+N# is though to master, but like chess in general, it comes with practice.
Watch videos on how it's done. Different teachers will give different ways to memorize the patterns. Find one you understand/like.
Set up a position with B+N and play it against the strongest computer, then analyze it, improve, and repeat until well done 
Best
P.S.: it also helps to know when you cannot win a game, and might want to accept a draw - or try to force a win by your opponent blundering (Cough Carlsen Cough)
I just watched the three-triangles method. It turns out one of my nuggets on this ending was in actuality the second triangle onward, so this method dovetails nicely.
