Excuse me. capture threats extensions are window dependant. for example if depth==0, but a rook of the side to move is being attacked by an enemy horsy for example then we can leave the qsearch, and captures are seen, but after, if eval<=alpha then alpha is returned at the moment since keep seeing other moves in this case have not any sense in the extension purpose(just see if the piece is lost and see at least what the qsearch does).
