Tewari is a heuristic to see whether stones are working well together.

There are two approaches to the concept of tewari.

  1. Take away an equal number of (superfluous) stones of both colors from a position. Then evaluate whether the remaining stones are working efficiently, in order to decide which side made the better moves.
  2. Invert or permute the order of moves, also called transposition, to see whether one would still have responded so that the actual position results. If this is not the case, that tells something about the previous moves.

For limitations see how to lie with tewari.
