Rules Question

[relyea]

No. This is incorrect. It’s always illegal to put your king in check (or to leave it there). Rule 3 states that if you make an illegal move, then your opponent gets two extra minutes. Rule 3A says (as a variation) that if you make an illegal move, then you lose. Playing (for example) BxK is merely a way of claiming that victory. It only is valid if rule 3A is in effect. Please note that this is different under FIDE rules, where Geurt Gijessen has stated many times in his column at chesscafe.com that capturing the king is an illegal move. Therefore, if you’re playing under FIDE rules, and if your opponent leaves his king in check, you can stop the clock and win, but if you capture the king, you lose.

I just ordered the 5th edition rulebook, so its in the mail.

According to the posts, if there is less than 5min on the clock, you can only rollback an illegal moves if no more than 2 more moves have been made. [ EDIT: I had to edit that line for it to make sense.]
Personally, I think 5min (or variations based on time delay) chess should have its own rating, and rules specific to blitz ches. I don’t want to debate that in this thread though. I believe that some blitz rules state that if an opponent makes a move that puts his king in check, the opposing player is allowed to capture the king, thus ending the game.

So, its technically legal to put a king in check in blitz chess, its not advisable. Now, these are rules specific to playing chess where the entire game from start to finish is 5min. Pretty sure the rules pre-dated time delay clocks, so not sure if using time-delay clocks, it would be advisable to continue the rule that allows a move that puts your own king in check. But like I said… if you put your king in check and the opponent sees it… you’ve pretty much lost the game.

You’re refering to 11D1, Illegal move in suddent death time pressure. Linking this situation to Blitz is innaccurate. If White makes a move in sudden death time pressure that leaves his King in check, and Black does not notice it, each subsequent move is illegal (see the TD Tip to 11A, which is cited in 11D1). The two-move rationale of 11D1 is understandable considering that move players stop recording moves at that point, but the TD Tip to 11D (which encompasses 11D1) makes it clear that King-in-check illegal move is a circumstance worth noting.

Blitz already has its own rules. See the website section Governance > Reports > BlitzRulesChanges.pdf for the latest Blitz rules. This document states, “Take note that Blitz is not Quick Chess with a 5 minute time control (which follow standard sudden death rules.)” Adding a time delay to a 5min time control makes it Quick chess, subject to Sudden Death rules.

Finally, Alex makes a good point on the difference in USCF and FIDE rules.

Thats the entire point: USCF used blitz rules only for fun. I wish they had a specific rating for it. But I’ve mentioned this ad nausum, so this is just another chance for me to blog about it.

I don’t know how viable it would be to have specific rating for blitz, but a vast majority of club games are done at G/5. -The reason is that most clubs only meet once a week for 3 to 4 hours, and it gives players a chance to maximize the number of opponents they play during the night.

When I say viable, I mean in the sense that, I don’t know how accurate a blitz rating would be compared to a person’s regular rating, but you would get alot more games played, so after a few years, meta ratings should be normalized. (meta means the average strengh of a player should be reflective of a similarly rated opponent, and reflect the scale that 1500 blitz is player is in the 50 percentile of all blitz players, and the bell curve should look similar to regular ratings.)
