Title: Is it valid according the FIDE chess rule?
ThreadText: # Is it valid according the FIDE chess rule?
  
  (Asked by: username_0 on 2019-08-05)
  
  From [FIDE Law of Chess, article 3.8](https://www.fide.com/fide/handbook.html?id=171&view=article), it is stated as:
  [![Castling Rule](https://i.sstatic.net/qYj1B.png)](https://i.sstatic.net/qYj1B.png)
  
  Now, coming to [My game vs killin\_pieces on lichess.org](https://lichess.org/PAXCH1gQ) :
  
  After move 9, situation was something like this: b1 was threatened by my opponent's light square bishop:
  
  [![position 9](https://i.sstatic.net/wn3Lg.png)](https://i.sstatic.net/wn3Lg.png)
  
  Still I was able to give him a discovered check on move no. 10.
  
  [![position 2](https://i.sstatic.net/2qxxF.png)](https://i.sstatic.net/2qxxF.png)
  
  which clearly contradicts FIDE Law of chess article 3.8.2.a, stated as :
  
  > Castling is prevented temporarily:
  > if the square on which the king stands, or **the square which it must cross**, or the square which it is to occupy, is attacked by one or more of the opponent's pieces
  
  Can anyone please explain me how can this be possible ?

  The king does not cross b1 (only the rook does). It also does not end up standing on b1 following the castling. Hence, the quoted rule is not violated.
