Recent Tournament Results & Club Championship

Last Thursday we dabbled yet again in the A4c variant with four rounds of G/10+0 action and it was surprising this time around how many matches went to the third game, even in the earlier rounds. I had given some thought to trying G/7+0 given a faster time control was suggested by the creator of this variant yet, given how poorly I performed with ten minutes on my clock, I’m perhaps fortunate we stuck with the longer time control (though it made little difference in my results). A few others bemoaned the seeming quickness of G/10+0 in this format but I don’t know that it would make sense to use anything longer. In any case, congratulations to Pranav Jindal for sole first place and for his perfect score in this event and to Hayden, Breakwell, Austin and newcomer Brice Huang for their T-2nd result with 3.0 out of 4 (full results are in the attached image).

Somewhat embarrassingly, in my second-round match with KornĂ©l Csernai, we reached game three with me up 1.5-0.5 and I promptly ran out of time in the third game, laboring under the delusion that the worst I could do was draw the match, never mind the result of that last game. We recorded the draw and moved on to the next round but it finally dawned on us after the tournament that Kornel should have received the full point — I needed to resign the third game with time still on my clock to secure the half point, it seems (something we’ll need to run by Alaric the next time we see him). Apologies again for cheating you out of that half point, Kornel! 🙂

Our Autumn Double-Round Quick-Rated Quads also wrapped up last week and the full results can be found on the associated tournament page. Congratulations to Hayden Brongersma, Breakwell Loyalka, Austin Chen, Caleb Leong and Saveen Sahni for the excellent performances in their respective groups and I hope to submit the quads for rating as soon as we resolve one expired US Chess membership. On a personal note I learned that, as bad as I am at time management in A4c chess, I’m even worse in these G/15;d5 games and was lucky to scrape the lone half point from Hugo Pu in our second game (it occurred to me that he may have gifted me that draw given it was all he needed to secure second place in our quad). Poorly as I did the chess was still enjoyable and I’m glad to have played, never mind that my Quick rating is quickly heading to three digits.

Note that our Club Championship begins tomorrow evening and runs through December 11th, something which will supplant the free, unrated blitz tournaments normally run on casual evenings. We may still have a skittles room set up for casual play but that won’t be certain until the night of each round. Please feel free to stop by the club to spectate the club championship games if you are not playing, of course, and have a great Holiday season if we won’t see you until next year! Regards,

A4c Variant Tournament #3

“A4c” or “The Clock (Almost) Never Stops” Variant

Background: One of the strongest blitz players in our club came up with this variant and, after hearing it described, we couldn’t resist holding two informal tournaments in 2024 to give it a try. It proved very popular so we’re giving it another go—it involves a good deal of fast chess plus a game within a game (a metagame) centered around how best to manage one’s fixed time allotment over several games.
Concept: Players will play best of 3 games against the same opponent in each round with 10 minutes on their clocks, with no increment or delay. When a game ends, players pause the clock but do not reset the time. They reset the pieces then restart the clock for the next game with the times remaining from the prior game(s). If a player runs out of time they lose the match. If a player wins the majority of the points possible in the 3 games, they win the match (so if a player wins two games and still has time remaining on their clock they win the match). One player gets two games with the white pieces (first and third games) and the other gets preferred clock side for all games.
Oddities: Clock location does not change so one player always keeps it on their preferred side. Typically the players start the game by drawing for colors then whomever wins the draw chooses White or Clockside, but given we’ll be holding a Swiss system tournament the player assigned White in any round gets two whites and the player assigned Black gets to choose clockside. (We could also allow the player who is assigned White by the pairing software to choose color preference or clockside to further complicate the metagame).
Comments: I like the metagame aspect of this format because it incentivizes players to manage their clock across multiple games with tactical decisions (whether it is burning down an opponent’s time when they are ahead on time or resigning quickly to preserve more time for subsequent games). It also allows a stronger slower player to manage their time differently and take more time to win the majority of games (though this is risky if they go into a third game after budgeting time poorly).
Format: As mentioned above, we will play 3 games at Gs/10 over three or possibly four rounds, depending upon when we get started, and we may split players into groups of 8-12 by rating if the tournament doesn’t start very near 7pm (leaving time for just three rounds), so please arrive a little earlier if at all possible.

A4c Variant Tournament #2

Background: This will be our second foray into A4c Chess and it’s long overdue, given how well our first such event was received.

A4c Variant Tournament

We enjoyed an excellent turnout this past Thursday for our first foray into A4c Chess, as we’re styling it (though the variant’s creator may yet object). As a reminder, this variant is best-of-three games against each opponent with ten total minutes on one’s clock, so time management across the two or three games in each match is critical. Indeed, we saw a number of matches in each round where time was used, how shall we say, less than optimally, which led to severe time crunches in the third game and to much clock slapping (sometimes in a vain attempt to stave off the inevitable loss on time)—it definitely made for interesting spectacle and was fun to watch. More information about the variant and the tournament details may be found here.

Twenty-eight people participated in three sections, which worked well for the three rounds we were able to squeeze in during the evening. Below are the results for each section and congratulations are due to winners Kunal (group one), David (group two) and Hayden and Austin (group three). Thank you to everyone who played in this event and the feedback was universally positive, even with the late start, so we’ll definitely play A4c Chess again soon.
