Talk:Seirawan chess

A fact from Seirawan chess appeared on Wikipedia's Main Page in the Did you know column on 17 August 2007. The text of the entry was as follows:

Did you know... that chess grandmaster Yasser Seirawan invented a new chess variant in 2007, Seirawan chess, which features two new pieces to the chess: elephant and hawk?

A record of the entry may be seen at Wikipedia:Recent additions/2007/August.

Purpose of example game

What purpose does the example game section serve in this article? It's a single game, with some arbitrary interpretation of it (which would appear to violate WP:OR and/or WP:NPOV). I can't see any justification for its inclusion. Oli Filth^(talk) 20:03, 3 November 2007 (UTC)[reply]

Explaination of rule.

If the player moves all his pieces from the first rank without placing either piece, he forfeits the right to do so.

This rule is not fully explained. For example if a player moves his last piece from it's original square and replaces it with a new Eagle, can you now move the Eagle to make room for the Elephant? neoliminal 02:36, 11 November 2007 (UTC)[reply]

To quote from http://www.chessmastery.com/seirawan-chess.html :

"Since each side has eight pieces (K, Q, R, R, B, B, N, N), a player has eight opportunities to bring the Hawk and Elephant into play. If a player fails to do so, the unplaced piece remains out of play."

It appears to me that the answer to your question is "no". Besides, it's called the Hawk, not the Eagle. --Sibahi 21:56, 11 November 2007 (UTC)[reply]

I have updated the rules to be explicit regarding how in-hand pieces are placed. DavidJHowe (talk) 22:02, 23 April 2008 (UTC)[reply]

Moving into Check

Is it legal to move my king into check (temporarily) as long as I place an in-hand piece to block the resulting check? Admitedly, this would be a rare case, but I think it should be covered in the rules.

White king is in check by black rook at c1. White moves king to f1 and places hawk at e1. Would White's move be legal?

This answer comes from Yasser Seirawan himself:

No. At no time can a player leave his King in check, even for a "half a move".

Example: Black's last move is 1...Rc1+. The White player cannot play 2.Kf1/Ee1. The White player could play 2.Ke2/Ee1 but cannot have exposed his King to the Rook check for "half a move." DavidJHowe (talk) 11:44, 24 April 2008 (UTC)[reply]

"If the player moves all his pieces from the first rank without placing one or both in hand pieces, he forfeits the right to do so."

But can he then still promote a pawn to one of them? Double sharp (talk) 15:33, 31 January 2016 (UTC)[reply]
