Still seems very silly to me. Even if, um, hypothetical. I do hope no chess players were disturbed...

Talking of which, are there chess engines you can use remotely over the internet?Roger de Coverly wrote: I suspect you can load a chess engine to an ipod

Re: British Chess Championships 2011
I don't know if there are any public ones, but it seems possible to connect your portable device to your private home computer network. That's hardly a surprise, since it's equivalent to old fashioned dumb terminal to main frame, which has been around for forty years.Christopher Kreuzer wrote:Talking of which, are there chess engines you can use remotely over the internet?Roger de Coverly wrote: I suspect you can load a chess engine to an ipod

Ian Kingston wrote:Attempting OCR on the average scoresheet would result in gibberish. Quite apart from the poor quality of handwriting of many players, people use a huge variety of idiosyncratic notations, such as short algebraic, long algebraic, colons to signify captures, algebraic but with descriptive notation for captures, no indication of captures, descriptive notation, non-English notation, clock times after every move, clock times at 10 move intervals etc.
GentlemenSteve Rooney wrote: Exactly. Using OCR to get game scores is highly optimistic and likely to take longer than someone entering the moves whilst deciphering the gibberish.
I wasnt thinking of standard OCR software being used in a two step methodology ie a) OCR b) check PGN for integrity.
The OCR modules need to have access to the AI of the PGN integrity checker all in one pass. This reduces the valid input alphabet and allows for using the next symbols(s) as further integrity checks. Thus the probability on information out takes in more information and should be more accurate.
This should be an M.Sc. project for someone ! I dont profess to know how education works anymore in this country but as McD seem to give out degrees why cant Chess and Bridge arrange something here ?

The handwriting appears to be continuous pen contact and therefore allows pen direction ratios to be used in addition to pattern displacement fuzzy logic. The results should be better; hard though it seems to be to believe it.

Re: British Chess Championships 2011
Can such algorithms cope with changing handwriting patterns over the course of a game? I've seen people's handwriting get worse in time trouble, degenerating from moderately clear to an indecipherable scrawl. I've also seen people instructed by the arbiter to complete their scoresheet just scribble meaninglessly if they can't remember the moves. Admittedly, in these cases, humans don't do much better at deciphering the scoresheet. Possibly also of interest would be a computer that could reconstruct moves. i.e. give it two positions and ask it to find x moves that get from one position to the other one.E Michael White wrote:The handwriting appears to be continuous pen contact and therefore allows pen direction ratios to be used in addition to pattern displacement fuzzy logic.

Re: British Chess Championships 2011
You would expect reliability to go down but not by much as the AI should have learnt from the first part of the game. For example in Sean’s, score sheet Blacks 1st move has three symbols so unless the 6 is wrong its either Nh6 or Nf6 but it clearly defines the shape of the C which in this gentleman’s notation is N. That makes Black’s moves 2, 3 and 6 and Whites moves 2,3,4,5 and 6 easier to understand which a two step system might find more difficult. In addition there would be fewer legal moves that match fewer symbols to select from as the game progresses.
IMHO looking at this area is much more sensible than cosmetic changes to the grading system of questionable value, that not everyone is happy with.
What has occured to me since posting is that the word Sunningdale would give the AI a free start as regards what (a,d,e,g) look like. Is this a good choice of location or is there anywhere else in the UK that Sean should choose to give more symbols than 4 out of KQBRNabcdefgh ?

Re: British Chess Championships 2011
Queniborough - thats good 5
I have since thought of :-
Badgeworth also 5
and
Buckfastleigh for a 7.

The n and r in Queniborough are lower case, for piece names they need to be uppper case but the g counts also, so only 5.Sean Hewitt wrote:6 surely? Q e N B R hE Michael White wrote:Queniborough - thats good 5
Thats only 3 :- abe, you cant count any twice and the n is lower case !Alex Holowczak wrote:How about here, which would be 8?

Yes - good but would anyone admit to getting an IM norm at the Queenstown Road (Battersea) railway station Masters A event ? It doesnt sound quite the same.IM Jack Rudd wrote:How about the Queenstown Road (Battersea) railway station, for Q R B a d e ?
