This position appeared in one of my online games. After the Knight blocked the defense of my Black Rook, I quickly resigned. In later analysis, I found there was a (somewhat) saving response.
There are two situations in a chess game where the clock no longer has a bearing. The first is when you are offered a draw and are inclined to accept. First examine the position carefully to see if there is a deeply hidden winning path.
The second situation appeared in the game snippet below. White had apparently finished trapping the Knight, leaving Black a piece + 2 Pawns down. Before resignation, always take the time to look for a saving response.
Resignation is always terminal. A chess player’s remorse is a terrible thing.
