Why is flagging considered a win?

I feel like you somewhat misunderstand the concept of a time control. The clock is a part of the game. If you are up a piece in a complicated position with five seconds left on the clock that may well ...

Game ended with a handshake

From my experience (small to medium central European Opens), offering a handshake without words is a commonly accepted form of resignation. The handshake is not part of any official rules. However, ...

Can a player in check win, by checkmating the opponent, while not getting themselves out of check?

For this kind of question, if you have doubts, just play chess with the goal of capturing the enemy king. The first player to capture the enemy king wins. This isn't the official rule, but it's ...

Can a player in check win, by checkmating the opponent, while not getting themselves out of check?

According the FIDE LAWS of CHESS: 3.9.2 No piece can be moved that will either expose the king of the same colour to check or leave that king in check. So as @djnavas points out, if you are in check ...

Because not having it would result in some perverse incentives. In particular, in any game where a draw is an acceptable outcome, the optimal strategy without flag drops being losses would be to never ...

There is neither checkmate nor stalemate, so why did black win?

Most probably White resigned. This is a common decision to be made in a desperate position such as this one, where there is no doubt Black will be able to win anyway and the 10 or 20 more moves ...

Can a player in check win, by checkmating the opponent, while not getting themselves out of check?

No, this is not legal. The fact that the black king is still in check from the white rook overrides every other consideration. It doesn't matter that (were it not for the white rook) Black's move ...

Why is pawn c6 is not winning here and what is the missed win for black?

Look at the diagram. The engine tells you the best move (Rd8). The idea behind that move is that it pins the white knight to the queen and at the same time attacks the knight a second time. Moving ...

Since you specifically asked for historical reasons: Think about your two proposed criteria in the context of the year 1800 or 1900. Using engine evaluation is obviously out of the question. So is &...

Is this endgame winnable for either side?

With white to move, as you indicated, it is a trivial win for white. Your rook on g8 is en prise to the white rook on g1. White plays RxR+ and you are just a rook down.

About how to win a pawn by applying pressure-Looking for examples

I am sorry to say that the answer is "no", there is no "easy way" to apply pressure and win a pawn in the opening, otherwise, at the top level of chess, the game would be won every time. That is what ...

In the picture, it could be either the two simply agreeing to the draw, or black resigning, depending on who has the move. Both are typically followed by a handshake. White to move is a draw. [FEN "...

Is there a terminology for "the worst winning move"?

In a winning position, the best move is the one with the shortest depth to mate. So, the “worst winning move” would be the one with maximal depth to mate. So it seems reasonable to call it the move ...

About how to win a pawn by applying pressure-Looking for examples

It's possible to win a pawn in the opening, but because it is the opening (i.e. heavily analyzed), you can't do it by force. You can only do it if the other side lets you. The Two Knight's Defense ...

Yes, Ne6 staves off mate, but it does not stave off the loss for long, but more importantly, it does not demonstrate the main point of the tactic, which is why they continue with the "worse" gxf6 in ...
