In general, a chess set has the king as the tallest piece, followed by queen, bishop, knight, rook and pawn in that order. Notice in the starting position how the piece height decreases smoothly from the centre to the edge. (Also, when buying a chess set, usually the height of the king is given as a guide to the size of the chessmen.)
Thus I would say the ...
Castling is extremely useful in almost all games. It lets you do two things at once. First, it moves your king from the center to the side of the board, where it is much more difficult to attack for the opponent. Second, it brings one of your rooks towards the center of the board, and it crucial in bringing both of your rook into the game.
There may be a ...
I know you're a FIDE Master :), so I suppose you're more interested in this question from a teaching perspective.
The simplest way to understand a checkmate with King and Rook vs King is the idea of the rectangle of the opposing king. Consider this position-
Here, the Black King is restricted by the White Rook in this giant rectangular area of the ...
Wikipedia claims that
In early Sanskrit chess (c. 500–700) the king could be captured and this ended the game. The Persians (c. 700–800) introduced the idea of warning that the king was under attack (announcing check in modern terminology). This was done to avoid the early and accidental end of a game. Later the Persians added the additional rule that a ...
There are three ways to get out of check.
Simply move the king away.
Block the check, or place a piece in between the king and the opponent's attacking piece.
Capture the piece that's checking the king.
All of these cases are dependent on the fact that immediately after you make your move, the king is not in check. Therefore, you may capture the queen ...
There are several key positions from which it is easy to memorize the win. The basic idea is to drive the opposing king to the edge of the board, and then to the corner, where you can force the rook to separate from the king.
[White "King and Queen"]
[Black "King and Rook"]

In many cases I felt no need to "reinvent the wheel" so I quoted the above authors. Those parts will be marked with apostrophes "", like this: "This is a quoted text".
Without further delay let us tackle this endgame:
"In endings of ...
At first glance, the taller piece with skinnier top would appear to be the King while the shorter, rounder piece would appear to be the Queen.
There are a few reasons why this would appear to be the case.
The King often has a cross on top and the taller piece with the spike appears to more closely resemble that than the shorter piece, and in some sets the ...
Your friend is right. Think of it in terms of capturing the king: check means that your king could be captured on your opponent's next move. If you could move your king next to your opponent's king, your king could be captured on your opponent's next move; the fact that after that you could capture your opponent's king doesn't change that: your king has been ...
Practically speaking, if the king were any more powerful, checkmate or capture would be impossible.
The Queen originated as the Advisor. The Advisor was powerful, but not as powerful as the modern Queen, however. Why did the Advisor become the Queen? Having more than one Queen per side would debase the game, and there are two each of the other pieces. ...
Putting your king in check is not a legal move as you've realized.
Of course, if Black has any OTHER legal moves he can and should play one of them!
If a side TO MOVE does not have ANY legal moves, that would be a stalemate, not a checkmate (which is delivered only by the side making the check)
If these are two real kings, it is not possible. This is because one requirement of checkmate is that the black king is in check which cannot be achieved with any of the white kings, since it would put the white king in check.
If you say that white has only one king and a nonstandard chess piece that moves exactly like a king (i.e. this piece can be put ...
A King and a Man (or commoner; i.e., a non-royal King) can mate a lone King. The longest distance to mate on a standard 8x8 board is 18 moves.
The result quoted above was obtained by H.G. Muller in 2008, see this coment on chessvariants.com: http://www.chessvariants.com/index/listcomments.php?id=28770
Your opponent has 50 moves, but every time a pawn is moved the count is reset. So, he could have hundreds of moves if he has a few pawns on the board. If he has no pawns, then 50.
The count is also reset if any piece or pawn is captured.
I would love to see the position; please add it to your question somehow (we can always edit it to look nice). However, there is no such rule. Either your computer doesn't implement captures en passant (improbable these days) or the capture was not valid for some other reason.
Your friend and the existing answer here are both right: You can't do that.
There's no explicit law of chess for just this situation because it's fully covered by a slightly more general article from the FIDE Laws of Chess:
3.9.1 The king is said to be 'in check' if it is attacked by one or more of the opponent's pieces, even if such pieces are ...
This is covered in FIDE's Laws of Chess 5.2b)
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. The game is said to end in a ‘dead position’. This immediately ends the game, provided that the move producing the position was in accordance with Article 3 and Articles 4.2 – ...
Your "checkless" chess AI would run into problems with the stalemate rule. It would consider the poaition with white king on a6, white pawn a7, black king a8, a win for White because wherever Black moves his king it will get captured. In standard chess, of course, the position is a draw.
It doesn't matter.
As long as you and your opponent are in agreement about which one is the king and which one is the queen, it doesn't really matter what they were "supposed" to be.
That said, if they're easy to mistake, then you run the risk of someone making a misplay because they got confused about which one is which. Which would be unfortunate. ...
The general rule of thumb is that: if the queens are off the board then it's generally safe to keep the kings central in order to use them as active pieces (specially in endgames) instead of tucking them away into a safe corner.
But that's just a general rule, and like any other rule in chess it is to be taken with caution, because at the end of the day ...
I know you mainly asked about the 50 move rule, and that has already been answered, but I thought I'd answer the exact question as stated which was "With the King as the last piece, how can you get a draw?"
Both players can agree to a draw
Opponent Stalemates you (you have no legal moves, but are not in check)
You stalemate your opponent (yes you can do ...
Since you can't move your king into check, you can't legally check the other king.
The Laws of Chess, section 5.2b, states that:
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. The game is said to end in a ‘dead position’. This immediately ends the game, provided that ...
A member of my club, rated about 1900 FIDE, had this in a championship blitz game about 2 years ago with 30 seconds left on the clock. He delivered mate with time to spare. IMs have failed. Go figure. If you study and learn then you should be able to deliver mate. If you don't study then you won't. Playing strength doesn't have that much to do with it.
Kd2 is indeed illegal. You can think of it this way: normally Black can't move his knight because White would "capture his king", but if White were able to play Kd2 then Black would capture White's king before White got a chance to capture his.
The piece on the right clearly reminds me of kings from German "Bundesform" piece sets, which are still occasionally used in Germany, although very rarely in tournament play. The left piece does not exactly look like a "Bundesform" queen, but it is still somehow similar.
The FIDE Laws of Chess say:
3.8 There are two different ways of moving the king: by moving to any adjoining square not attacked by one or more of the opponent’s pieces
3.9 The king is said to be 'in check' if it is attacked by one or more of the opponent's pieces, even if such pieces are constrained from
moving to that square because they ...
