Recapture Extensions

Recapture Extensions are a subset of Capture Extensions, restricted to recaptures to the same target square. A recapture is supposed to be a relatively forced move. However, some programmers consider any two consecutive captures, or even any capture with respect to an intermediate Zwischenzug , if it restores the material balance of the root as recapture, while others recently favor to restrict them to PV-nodes only.
