generateMoves()

generateAtLeastOneMove()

movenum_t bMoveList::generateAtLeastOneMove

(

see if at least one move can be played e.g.

(stale-)mate eval

Returns

case last evaluated + 1, 0 if no moves found return range: >= 0 and <= 64 updates m_generateFromCase

generateEscapeKingMove()

movenum_t bMoveList::generateEscapeKingMove

(

bBoard const &

b

)

see if at least one move can be played e.g.

(stale-)mate eval in case player is in check, to speed up, start with king position

Returns

case last evaluated + 1, 0 if no moves found return range: >= 0 and <= 64 updates m_generateFromCase, but should not be used in conjunction with generateAtLeastOneQSMove and generateMoves because it will insert kingmoves twice (wrong movecount!)

generateAtLeastOneQSMove()

movenum_t bMoveList::generateAtLeastOneQSMove

Returns

case last evaluated + 1, 0 if no QS moves found return range: >= 0 and <= 64 updates m_generateFromCase and might generate all moves
