I’m continuing to discover changes to FIDE’s regulations from 1 July 2014. (Is there a useful summary of changes published anywhere?) As well as draw by 5-fold repetition without requiring to claim and requirements for trainers to be licensed, I notice that there is a 75 move rule. It is the same as the 50 move but without either side needing to claim. I wonder how many times that one will be invoked?
Slovenia’s 15 year old board 4 gained an enormous 84 points over the month of July. Immediate concerns that she is the next Polgar subside when her results are checked. Some games are on K factor of 15 but others use 40! To explain the new Ks:
K is the development coefficient.
K = 40 for a player new to the rating list until he has completed events with at least 30 games
K = 20 as long as a player's rating remains under 2400.
K = 10 once a player's published rating has reached 2400 and remains at that level subsequently, even if the rating drops below 2400.
K = 40 for all players until their 18th birthday, as long as their rating remains under 2300
The new regulations will mean greater movement in ratings especially for newly rated players and improving juniors.
Ali goes for it early in a Sicilian Kan with f4. Our silicon friends shake their heads disapprovingly but it creates a tactical mess with Black’s king is stuck on e8. Difficult for humans to work out what is going on but perhaps Ali needed to sacrifice a further pawn with e6 to keep Black’s king in the centre. It escaped to the queenside and Ali’s king came under heavy fire.
Elaine’s WGM opponent has a reputation for liking theoretical lines so Sicilian with 3...Qd8 seemed a reasonable choice. If another recommendation was needed then Magnus had tried it the previous round. However playing ...Bg7 and ...Bxh6 on successive moves lost time and made it difficult for the king to find a safe haven. Elaine wasn’t allowed to get going today.
Carey’s Benko gave her typical dark squared counterplay for the pawn. Recovering the pawn with ...Bxc3 and ...Rxa4 was a double edged decision that needed a dynamic follow-up. Carey missed White’s c4 idea and the weak dark squares and backward d-pawn became significant factors. She fought on an exchange down until White found a zugzwang idea that forced the loss of a pawn and resignation.
Once again Keti was last to finish. Perhaps this was to be expected after the huge amount of time consumed by both sides around moves 3 to 5 in a Bishop’s opening. The Slovenian fell asleep on move 3 and awoke after at least 30 minutes. Keti needs no encouragement to think and caught the same bug. The problem with this approach is that once the time is gone you have to rely on 30 second increments. I’m relieved I’m not watching with a computer running in the background as the evaluation shoots up and down in time trouble. Not good for the health of any Scottish fans watching but Keti eventually secured the point when her monster d-pawn won a knight.
