Subject: Fast check detection in bitboard engine

Hello,

Is there a fast technique to detect that a king is in check in a bitboard engine
? In my engine I generate all capture moves and try them to see if the king can
be captured...but this seems very slow !

I use check detection mainly in two parts of the engine :
- During move generation to avoid generating illegal moves
- To activate check extensions

Is there a way to avoid check detection during move generation ?

Thank you :)
