Verified SEE pruning for capturing and checking moves. Patch analyzes field after SEE exchanges concluded with a recapture by the opponent: if opponent Queen/Rook/King results under attack after the exchanges, we consider the move sharp and don't prune it. Important note: By accident I forgot to adjust 'occupied' when the king takes part in the exchanges. As result of this a move is considered sharp too, when opponent king apparently can evade check by recapturing. Surprisingly this seems contribute to patch's strength.
