The ironing is delicious

One of the more borderline cases in 'sudden death' chess is K+R v K+R Normally sensible players would agree to a draw one the last pawn cam off the board (and their were no immediate mates or tricks) but some players insist they can play one. 

I had such a case in a junior rapid I was running today, where the aforementioned position occurred. I was alerted to it by an illegal move claim, and I dutifully gave an extra minute to the player making the claim. This left him with 9 minutes and his opponent 8 minutes. The opponent then offered a draw, but the player with the extra minute insisted on playing on. Maybe he was hoping for a 2nd illegal move (which would have been a poor way to win), or maybe he was hoping to flag his opponent. But in avoiding any repetitions etc he managed to get his pushed to the edge of the board, where all he need to do was check the opponents king to avoid mate. But did he do so? Of course not! He moved his rook and then seemed shocked when his opponent mated him. 

So my usual speech about poor sportsmanship was replaced with a speech about karma instead.

Better OCR with AI

 I've been avoiding the whole AI revolution (ChatGPT etc) if only because I have seen earlier attempts fail (going bake into the 1980's). But I deided to see if it could solve one issue for me, and it seems to have done so.

Converting old chessbooks (out of copyright of course) into text has been a challenge in the past. The formats and notations left traditional OCR software struggling, and the unusual fonts also lead to trouble. But I threw the first page of an old pdf I have titled "Chess Sparks" into it, and after 15 seconds it came back with 


"CHESS SPARKS.


1.

This game affords the earliest instance on record of a kind of mate,

of which many examples will be found in the following pages.


It was played by M. de Kermur, Sire de Légal, who was born in 1702, and at the age of 85 was still the best Chess player in France, after his pupil Philidor.

19 B–KKt5      and wins."

which appears to be an accurate translation of the moves, and the notes.

Assuming that the level of accuracy holds up, then I look forward to resurrecting some of the more ancient works in a quick and easy manner.

2025 ACT Junior Chess Championship

 Congratulations to Sanat Hegde for winning the 2025 ACT Junior Chess Championship. He scored an amazing 8.5/9, with ACT Girls Junior Champion Sahasra Selva the only player to take a half point off him. Amazingly, Hegde was eligible for the Under 8 section (having turned 8 this year). He won the ACT Under 10 Championship last weekend (it was a combined Under 8/10 event), but curiously, was runner up in the Under 12 Championship. 

Masaki Horikawa finished 2nd in the championship (winning the Under 16 title), with Nivin Vinothkumar 3rd and Owen MacMullin 4th. There were a number of interesting games, including the following one, which decided the final placings in the event.
