It's a chess forum and nobody knows the answer? ?
Staff, anyone come on show me some knowledge!
ATTENTION Experts + please help me out here, only if you really know FIDE rules
Sort:
If you only have one knight and you win on time then on chess.com servers you get a draw of insufficient material! I think in Fide you just win the game.
Basically you can mate someone with: a rook, a queen, two knights ( with a little help from your opponent), two bishops, a knight and bishop
From https://www.fide.com/fide/handbook.html?id=171&view=article
"6.9 Except where one of Articles 5.1.a, 5.1.b, 5.2.a, 5.2.b, 5.2.c applies, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by that player. However, the game is drawn if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves."
"5.2 The game is drawn when a position has arisen in which neither player can checkmate the opponent’s king with any series of legal moves."
So in the video you describe, according to these rules, timeout against one knight and a king with a king and one piece is a loss, because there is a serie of legal moves that leads to a mate, although with perfect (and easy) play and sufficient time, the game is drawn either by the capture of one knight or by the 50 moves rules.
These rules are from 2014, so maybe then the arbiter had more freedom to make his judgement, which is bad, because players should know the rules by which they play.
https://en.wikipedia.org/wiki/Chess_endgame lists the theoretical endgame where the stronnger side can generally force a win.
one or two knight cannot force a mate, but two knights can mate a bare king if the opponent is careless (in a corner, easy to avoid), and one knight against a piece or more can, if the oppoonent actively helps you, so these games should be drawn, assuming perfect play and no time limit, but in case of timeout, the knight player can win the game. The three such endgames (theoretical draw, but legally possible win) I know are :
- two knights against bare king
- one knight against a king and a piece/pawn (against pawn, some(rare)times, win can be forced, better if you got two knights)
- one bishop against a king some piece/pawn (bishop against corner pawn works, as well as bishop against opposite colour bishop, and bishop against knight (thus against any pawn), don't know for the other cases, but I'd say it's not legally possible to mate)
As far as I know, if you got more material you still can legally checkmate, and it is a known theoretical endgame (listed in the wiki link above) where one side can usually force a win or the other a draw.
Edit : some imprecisions/errors are corrected by Jsaepuru in his/her next 2 posts, thank you!

You can not mate with only one knight and nothing else, nor one bishop and nothing else.
In all chess games(including FIDE) if a player has a Knight or a Bishop and the opponent has only the King left, or both sides only have the Kings, the game is drawn by insufficient material.

True.
In the game of the youtube video linked in the OP, each side has a knight and king, so the game should not be drawn by insufficient material, at least not by current FIDE rules. It is a theoretical draw, and an easy one to play, but mate still is legally possible.

Most of people here are more occupied on trolling than playing chess.

Kings and any number of bishops on the same colour cannot possibly checkmate, so that´s a draw for impossibility of checkmate.
A bishop and a king can checkmate a king and opposite colour bishop, or a king and a knight, or a king and a pawn. So can a knight.
A knight can also checkmate a king and a rook:
A bishop cannot checkmate king and rook: if the checking bishop were on b2, the rook could capture him, and if he were on c3 or beyond on the diagonal, the rook could interpose.
Neither minor piece can checkmate king and queen: a bishop cannot for the same reason as he cannot checkmate the rook, and a knight cannot because if he´s checking then she can capture him.
Therefore either minor piece against queen, or bishop against rook, is a draw for impossibility of checkmate when the major piece runs out of time.

In OTB events there is also the situation that a player can appeal to arbiter that opponent is not trying to win by normal means, i.e is shuffling peices until opponent's time runs out. You have to make the appeal before your time runs out though.
King + 2 Knights Can Not checkmate King alone , nobody said that !

Not only corner:
Black to move is checkmated in the middle of an edge. Easy to avoid, but perfectly legal.

Not true, although checkmating with two Knights is hard, it can be achieved:
OMG this website full of trolls, kids and uneducated people!
For those who's saying that you can checkmate with 2 KNIGHTS vs the KING alone such a noob! !! Ahahahaha
Obviously you can but only theoretically, so it = same as you can't coz you will never be able to any way.
All the noobs I like to see you can continue this thread that you can checkmate someone wit two knights ahahahaha
I like to see those noobs playing in real life all all day long with two knights and still not checkmating ahahahaha
That's why I particularly mentioned EXPERTS + I don't have time for such noobs with their guessing games

You cannot. That´s where the 50 move and 3-fold repetition come in. The lone king can easily avoid blundering into the two knight checkmate... provided he has any time.
Running out of time has the same effect as blundering - meaning that a lone king against two knights loses under Fide rules, and so does a rook against knight.
IT'S IMPOSSIBLE TO CHECKMATE WITH TWO KNIGHTS! !!!!!!!!! NO metter what are the circumstances it's physically IMPOSSIBLE no metter of the circumstances!
It's only possible on a peace of paper!
Another noob!

So basically you can checkmate some one with one night and win? If their time runs out you win? Draw?
What about one bishop?
Can you name all the pieces that you can checkmate and when it's a win and when lost?
If you only have one knight and he got so many peaces he lost on time , it's a win or draw? Why?
