TL;DR: Claiming draws based on threefold repetition or the fifty-move rule is possible in rapid and blitz games as well. Contrary to RemcoGerlich's answer, it is not strictly necessary to record the moves to be able to claim a draw.
Note: This is based on the version of the Laws coming into effect after 1 July, 2017. However, as I am not aware of changes ...
2.f4 is a poor move, just like 1.Nh3 was. 1.Nh3 puts White at roughly -0.50; then, after 1...Nh6 White comes back to around 0.3. If Carlsen had played 2.d4, like you said, he would have maintained this evaluation. Instead, 2.f4 brings things down to -0.4ish.
A reason behind 2.f4 is to bring the knight back to f2, but it's still a bad move. As I mentioned in ...
The mate stands and white wins. Although the position both before and after the mating move is illegal the mating move itself is legal therefore article 5.1.a is satisfied.
If an arbiter observes black playing 1...Qc5 then they declare the game lost for black for playing an illegal move. If they do not see the move but they observe the position after 1......
You should read the rules from this page, sections A and B. Also, I would strongly advise you to ask a referee about this just to be safe from making a mistake or from embarrassing yourself. You can come earlier before the game starts ( 1 hour will be enough for the referee to explain you everything you need to know and for you to have time to relax and ...
Rapid and Blitz are both form of fast chess
Rapid, as the name suggests, is a faster version of chess
Time controls for each player in a game of rapid chess are, according to FIDE, more than 10 minutes, but less than 60 minutes. Rapid chess can be played with or without time increments for each move.
Many tournaments with a large player count opt for this ...
But in practice what is the average encountered in all or most tournaments? Or even a distribution for high endish , low endish, middling value? And which of those is prevalent?
This page will let you see every tournament that was rated in a particular state in a particular month. It takes a little effort from there to click through and see what the time ...
The Nh3 already, after the first move, does not have a good square, so he created one, f2. If he plays it to g5 after d5, then why did it not just go to f3? You don't want to move it back to g1 either. The worst though is moving it to f4 where it is sure to get knocked around and lose development time.
I think is also was consistent with his desire to take ...
This is not different from rapid chess and will be rated only for the rapid Elo.
The name "new classical" is part of a push to shorten the classical time controls. Originally the idea was to have a time control with around 60 min per game, but in the end they decided to shorten it a little to make the games eligible for the rapid rating at least.
Laws of Chess: For competitions starting on or after 1 July 2014
Article 7: Irregularities
If an irregularity occurs and the pieces have to be restored to a
previous position, the arbiter shall use his best judgement to
determine the times to be shown on the chessclock. This includes the
right not to change the clock times. He shall ...
In general, yes, all of the games played in an official event count and can make you lose or win rating points.
For example, rapid tiebreaks in the World Cup count for the rapid FIDE rating, while the Armageddon tiebreaks count as blitz. In the Norway Chess, the classification process via blitz games also counts for the FIDE blitz rating.
I have no mathematical formula to calculate the value of a knight or bishop depending on the time control (which is a related question and was asked here), but as I am mainly a Chess.com user and thus play blitz and rapid on the internet, I'll try to make an educated guess. My answer will be based on chess played with a mouse, not OTB.
There are several ...
IA Petr Harasimovic's opinion notwithstanding the game is drawn. Winning the game in an illegal position is a nonsense (barring serious misconduct or a ringing mobile phone). The problem is that the English (authoratative) version of the rules is ambiguously worded -
Then, if the illegal position is still on the board, he shall declare
the game drawn.
Rapid ratings cover a very wide range of time controls and bump up
against regular (where games are dual rated)
It is perhaps worth spelling these out for those outside the US who are unfamiliar with USCF time controls. According to the USCF's Official Rules of Chess (thanks, DM, for the link!):
5C. Ratable time controls.
There are three rating ...
They are time controls for chess used in relatively quick short games.
The actual time amount depends on how is defining them.
Blitz used to be zero seconds per move before digital clocks evolved.
Rapid used to mean exactly ten seconds a move before clocks came into more widespread use and then it was 5 minutes (or ten minutes) per person for the entire game....
It is a bit different from standard rapid chess because it is longer than the usual time controls used.
In the last World Rapid Championship, held in Berlin, the time control was of 15 minutes plus 10 second per move and it is also usual to held tournaments with 25'+5" time controls (like the rapid in the GCT tiebreaks).
The ratings calculations will be ...
In my personal opinion, the answers which follow from rules seem to be: White wins in the first case (checkmate), draw in the second case (the situation of Appendix A.4.d happened before checkmate). Although, this seems a bit illogical since the only difference between the two situations is the time when the referee was present near the table.
The Knight is not stronger in blitz, such a statement is nonsense.
It is you that are weaker at calculating at blitz, and the Knight is simply more difficult to handle with less time to calculate due to the kind of moves you can make with it.
So it's matter of how your brain handles Knights nothing intrinsic in the Knight.
