SEE is done per square. Rxe3 or Qxe3 (otherwize is an equal or good capture
anyway, you can do a litle trick here) must be followed by possible black
capturs on e3 and only e3. Captures on d5 are a different story. Quiescent
search handles those captures anyway, SEE tries to order the captures in a
expected material gain manner.
