Thanx Wrenn...

easy rule

It seems like we are discussing applications of the rules for castling without ever actually making them clear, or what castling itself is clear.

Prerequisites:

1. The King cannot have moved.

2. The Rook cannot have moved.

3. There must be no pieces in between the King and the Rook.

 

Castling:

1. Move the King two squares to the left or right.

2.Move the Rook on the opposite side of the King.

 

Cautions:

1. The King cannot castle out of check.

2. The King cannot castle through check.

3. The King cannot castle into check.

Emily, the knight cant attack f8 so i think u mean the bishop?

 

 

 

 

 

 

 

Emily, after Bxf8 then black will be up a piece. 

Thanx for posting such an article,which is very useful  to the learners of this game like me,who are ignorant about many such rules!

"On 1...0-0-0 White should play 2.Nxb6+ axb6 3.Kxg2 winning a pawn."

Why not 2.NxF8?

Then after 2...Bc6 (to trap the knight and keep from losing a piece) white has two appealing options: 3.Nxe6 (which isolates a black pawn) or 3.NxH7 which prevents black from castling and moves the H8 rook to a weak position.

Viktor Korchnoi asked the arbiter, O'Kelly, about the castling rule in his Candidates Match in 1974 against Anatoly Karpov. It was in game 21 on move 18. Korchnoi then played 0-0 with his rook on h1 attacked by a bishop on d5 (his g-pawn was on g3). Another game, Yuri Averbakh-CJS Purdy, Australian Championship 1960, saw Averbakh claim 14...0-0-0 was illegal while White's rook on b1 covered b8. Purdy, without speaking Russian, convinced Averbakh, who spoke no English, that his move was legal. I don't know why Yuri was in that event. When I met him in Florida in 2004, he was competent in English.

Just out of interest, does anyone know the game and the position where "Even Viktor Korchnoi had to ask about that rule." From what I have read, his was similar to this posting, as a young player he had been incorrectly informed about castling and just happened to have a similar position in the game concerned. Even though he thought he could castle, he decided to play it safe and asked the arbiter to be sure.

BUT YOU CAN CASTLE IN THIS POSITION!!!

well if you can not castle then do not castle

Its not castle in check. if black castles queenside the square that the white knight has control over is behind the black king. Remember that at castling the king only moves 2 squares to left or right!

i dont understand.  You can't move into check so how can castling into check be legal?

 

On 1...0-0-0 White should play 2.Nxb6+ axb6 3.Kxg2 winning a pawn.

On 1...Bd6 2.Bxd6 Kxd7 3.Be5+ wins a piece.

Black should play 1...Bc6 2.Ne5 Bb7 and if 3.Nc4 Rc8 with the idea of Be7 and 0-0.

On the castling rule you are correct. Even Viktor Korchnoi had to ask about that rule.
