We currently don't store scoresheets when uploaded to our website. Would you be able to send the pictures to us at info@reinechess.com? You could add comments about how it went (or not, since we can just run it and see for ourselves). If you think that might be a hassle I could quickly add a feedback form on the website. Also, I'd encourage that you try it once before the tourney with the restrictions—we haven't test…

Is there a reason you don't store the images of submitted games? Acquiring real-world training data to test changes with would be very useful. Perhaps make it an opt-in feature people can select when uploading a game so people are "offering" you this information to you rather than you just "taking" it. One way to choose between two legal candidate moves would be to look forward for the next move by the candidate piec…

No, not a clear reason other than wanted to get the product out earlier. We'll work on an opt-in, that does sound the best.

Wouldn't other pieces affect this though? For example, what if the move was e6 and the next e-pawn move was e7. What if a piece was already there, Ne7 (wrongly recognized)? I thought about slowly running through it like this, but it felt like I kept running into problems which are obvious for us to recognize but I wasn't sure how to implement it computationally

Hmm... I see why it's a hassle. How does it defeat he purpose though?

The USCF rules state that the TD can require players to use a specific scoresheet. It's not generally used in most casual tournaments, but almost mandatory for tournaments that matter.

I don't know about the US, but eg. scoresheets with carbon coy were handed out in the last tournament I played (Italy).

Another way to make them to scan would be that there is one space you can just write free text and then next to them you can fill in the circles to indicate rank moved from, file moved from, rank moved to, file moved to, and promotion (if applicable). You can indicate castling by the king's move.

That would be an awful lot of bubbles per move, no?

Yes, although there are ways to reduce it (perhaps in a way similar to POSTNET; this would reduce the space taken up but require more fill in at once). But you do not have to fill it in right away you can do so after the game is finish

Would you mind quickly explaining what you guys mean? Sorry, I'd love to improve it but I'm not sure I get it. If you had a bunch of bubbles for each square and piece etc. wouldn't you be taking up much more space than 5 boxes? And it's also a huge notation change for everyone
