i cannot believe - in a check my opponet just decided to go for rochade, the tower of him was attack

hey whats going on here ???? - my Opponent goes for Rochade in a Position where his Tower was attacked ???

what are the rules here ?

The rock can be attacked, the king can't. The rook can go through an attacked square, the king can't.

Look i am 48 years old. In good old games i.e. Karpow vs Kasparow in a time 1982 the rules were clear, even 0-0-0 was not possible if only one position between was threatened.-

en.wikipedia.org/wiki/Castling#Requirements

And the good old rules seemed a bit different indeed
en.wikipedia.org/wiki/Castling#History

The king cannot move through an attacked square. The rook can. The king can't castle if it is attacked. But you can castle if your rook is attacked. You can trust me on this, i know how castling works.

that means djullem --> in a check (vs Tower, you know what i mean) - now the rules are: I make Rochade ??? to Escape ???

Let me provide some examples:

King check, castling is illegal: lichess.org/study/VVkx5ojo/T2sdAbsC#9

King moving through attacked square, castling is illegal: lichess.org/study/VVkx5ojo/WRWV9ex7#9

Rook is under attack: castling is legal: lichess.org/study/VVkx5ojo/kmisIqek#11

Both rook and king has to move through attacked squares, castling is illegal: lichess.org/study/VVkx5ojo/5iSKQLzH#15

Rook has to move through attacked sqaure, castling is legal: lichess.org/study/VVkx5ojo/Pxi0XHr2#9.

This has been the case for over 100 years. Both during Kasparov and Karpovs reign.

You can also check out: lichess.org/learn#/14 which is a really good introduction to castling.

I think this is what you're referring to - your Bb2 is attacking his Rh8 and he castles out of it.
This is legal, because it doesn't matter that the rook is attacked; only if the king is attacked.

The king cannot therefore castle if he is in check or would move through a square where he would be in check. Here, you aren't controlling the f8 or g8 squares, only the h8 square (which the king never touches) so castling is legal.

Hey Lovlas,

nice to see i am Right - consequences ?

No, you are wrong. The rook can move through squares that are attacked.
