In chess, an isolated pawn is a pawn that has no friendly pawn on an adjacent file. Isolated pawns are usually a weakness because they cannot be protected by other pawns. The square in front of the pawn may become a good outpost for the opponent to anchor pieces.
The example here is a study by Henri Rinck first published in La Stratégie in 1920. It is White to play and win. Normally, Black would be able to sacrifice his rook for the white bishop, leaving a drawn position (sacrificing it for a knight would be no good, since it is possible to force mate with bishop and knight), but in this case it turns out that the rook is dominated, and its capture ...
Like the Poisoned Pawn Variation in the Sicilian Najdorf, this line gives significant weaknesses for both sides and can lead to highly complex lines. White can attack on the kingside and try to exploit the passed h-pawn, while Black destroys the centre .
In chess, a desperado is a piece that is (in the first meaning) either en prise or trapped, but captures an enemy piece before it is itself captured in order to compensate the loss a little, or (in the second meaning) is used as a sacrifice that will result in stalemate if it is captured. [1]
