Highly original Thinking is Paul Motwani's description of the acronym-based approach he advocates fpr chess thinking.
Those who play H.O.T. chess will build up a whole armoury of mnemonics to help them concentrate on key chessboard issues, even in the full heat of battle. using these concepts you will automatically give due thought to king safety, pawn structure, etc. and so come to a more useful, obejective assessment of positions.
