In chess, the isolated queen pawn (IQP) is a pawn structure that occurs when a pawn on the d file stands alone and is not supported by a pawn on an adjacent file. This structure can create unique challenges and opportunities for both sides, as the IQP can be a liability or an asset, depending on the situation. GM R B Ramesh teaches how to play against Isolated Queen Pawn through an illustrative game played between former world champion Botvinnik vs Zagoriansky in 1943.
