Hi,
this may be a simple question, but:
Can you castle across a square attacked by a Knight?
Or is it only a line of check, like from a Queen, Rook, or Bishop that you can not castle across?
Thanks!

I remember now, there was such an incident involving Averbakh. A
Google search shows it was mentioned here not long ago by a poster
named Terry ([email protected]). He wrote:
Pages 38 and 39 in Chess Catechism. It quotes October 1960, Chess
World. The game was Averbach Vs Purdy. Purdy as Black castled
queenside. His Rook passed through the attacked b file. "Averbach
pointed out that Purdy's Rook had crossed an attacked square and
therefore castling was illegal. When Purdy proved the rule on this
point only applied to the King, Averbach exclaimed: 'Only the King? Not
the Rook?'"
It appears the game was Averbakh-Purdy, Australian Championship,
Adelaide 1960. Here is the score as given in the ChessBase Mega
Database 2005:
[Event "AUS-ch"]
[Site "Adelaide"]
[Date "1960.10.08"]
[Round "4"]

This must be the move that surprised Averbakh. He assumed that with
his Rb1 attacking b8, Black could not castle.

A similar question, about whether castling is legal when the rook
involved is under attack, came up here a few weeks ago. I don't recall
any such incident involving Averbakh. You may be thinking of
Korchnoi-Karpov, Candidates Finals match, Moscow 1974, game 21:
1.d4 Nf6 2.Nf3 e6 3.g3 b6 4.Bg2 Bb7 5.c4 Be7 6.Nc3 O-O 7.Qc2 c5 8.d5
exd5 9.Ng5 Nc6 10.Nxd5 g6 11.Qd2! Nxd5? 12.Bxd5 Rb8? 13.Nxh7! Re8
14.Qh6 Ne5 15.Ng5 Bxg5 16.Bxg5 Qxg5 17.Qxg5 Bxd5
The Rh1 is attacked by the Bd5. It was here, I believe, that Korchnoi
asked the arbiter if castling was legal. It is. The game proceeded:
18.O-O Bxc4 19.f4 [1:0]

Here you can find the official laws of chess:
http://www.fide.com/official/handbook.asp?level=EE101
***
(1) The right for castling has been lost:
1.
if the king has already moved, or
2.
with a rook that has already moved
(2) Castling is prevented temporarily
1.
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.
2.
if there is any piece between the king and the rook with which
castling is to be effected.

The King may not castle through a square attacked by any piece, including
the knight (or pawn, for that matter). A rook can move through an attacked
square when castling.

I would strongly advise people to carry around a copy of the "official rules
of chess" for this situation, as that debate can get very heated.
One time in a coffeehouse some idiot with his girlfriend next to him was
playing me, told me I couldn't castle because I had BEEN IN check, I didn't
protest, castled by hand, then wiped him off the board in a half-dozen moves
after that anyway. He was pissed.

That's a common misapprehension. I've no idea where it comes from.

Well, for example suppose white has Na6, black has Ra8 and Ke8. Then 0-0-0
by black is legal, even though b8 is attacked by the white knight.

According to legend, neither did one of the well-known Soviet
grandmasters (Averbakh?), in a highly public setting.
