Obscure rule, or bug?

Hi

This has had me curious for a while, and I've found no answers, so I thought I'd see if anyone here knows.

Windows Vista/7's Chess Titans seems to allow you to castle through check if the attacking piece is a pawn. I thought castling through check is illegal, full stop? I've searched and searched but nowhere can I find anything that says that pawns are an exception to that rule. My chess book (The Right Way To Play Chess by D.Brine Pritchard) doesn't mention it either. The other day I encountered a similar situation here on chess.com and it didn't let me do it. The only thing I've found is a Youtube video of bugs in Chess Titans, but lots of people on there thought En Passant was a bug! I believe this is illegal, but can anyone here confirm that's indeed the case and it's not some obscure rule I'm unaware of? Thanks

clearly a program glitch

It is illegal. Any castling over a check is illegal.

By the way, howd the pawn get all the way over there? ._.

Why would anyone want to castle in that position anyway?  The pawn just takes the rook.

I figured as much. Typical bug-ridden stuff that they never bother to fix.

@Trapper4:

The e2 pawn you mean? I actually staged this, but only to demonstrate the situation (I don't usually play games agianst myself ). I'm too lazy to play dozens of games against the computer until I encounter a position like the one I described . I just played whatever moves popped into my head. As you can see in the first picture, there was a much better move. Not that it matters anyhow .

@breakerofwind:

I know, but that's not the point of this thread. The point is it's illegal.

whoever program the Titans should be given a new job (somewhere else)!

You think this is bad? Here's the video I was talking about:

Thankfully, the other ones have never happened to me though.

My solution: play chess against humans

yeah that titans thing belong to the rubbish bin.

Wow! That will show the king who's boss!

Humans have glitches too.

At least this glitch doesn't happen on the old Microsoft Chess program.

Generally, online sites with many players have less issues - leaving the issue unfixed enrages a large portion of the customers, and membership numbers will plummet.

This glitch is in a chess programme, not this site.

I'm aware - programs generally have more glitches. I rarely use them, with execeptions of CB and a particularly reliable, free, engine (Stockfish)

 White to move, but can't castle?  Why should black's rook have influence over squares it can't even legally move to?  Where's the logic in that?

Well, it's the same logic as making Kd1 illegal - I capture you first!

"Well, it's the same logic as making Kd1 illegal - I capture you first!"

That's the only explantion and if the object of the game was to literally capture the King, it'd make sense. But players can't check themselves under current rules.

Where else in chess does a piece influence squares it can't legally move to?  Seems wrong.

It is a long-established part of chess, dating to at least the early 1800's, that the pieces can shoot lasers and prevent the king from moving, even if the piece can't legally move.

That rule dates back to the days when they used sharks with lasers on their heads instead of rooks.
