Post the answers for the holiday chess puzzler 2018 here!

anyone know 11 and 13?

Bad Dobby Please tell all the answers you know so that I can upload a clear list of correct answers before they shut down the puzzler

Would exchange no 7 (verified!) for identification of the games in one or more of the 3 diagrams.

I verified all the other answers.

Oh Christian. Can you disclose the other answers than 7? and some answers you dont know? It would be really helpful.

I've been working all day on this. And I searched hundreds of games to find these positions without success. So I don't know 6-8-10. I would say no 6 looks like a spanish game where white is better. If we post all answers, where is the challenge? Would you give your Magic cards without wanting an exchange? would you give all the answers of an exam to everybody?

Hey Christian, I found #8 by setting up the position on an analysis board; the game came up under the opening explorer. Don't think we should give away the answer completely, but Carlsen played black, and the game was played within the past 2 years. How were you able to confirm #7? Did you find the actual photo? Also, can't find #6 or #10 in any database, so thinking they must be recent games. Don't look like anything from this year's WC though.

@MrDreste. I found the exact same jewels, the watch and the wristbands of right hand. The photo was slightly different but similar. I first looked for the reddish tablecloth in a tournament. Guess this was in China (only place I saw that kind of color). Hope it helps. I would say look into it and pin the rest.

anthony how do you know 5 and 19?

for some reason when i enter the evaluation one into stockfish, it says white is winning by a lot, then shows a bunch of moves, and then, in a completely won position, says it's a draw and continues on by playing pointless moves

Anthony, what makes you think Gwain Jones? The background makes it look like a Tata Steel Tournament, but I'm not finding a pic of anyone there in that exact outfit. Also, 18 is a pretty easy google search.

Thank you so much Anthony! Thanks for sharing your answers!

3: Rook

4: Vladimir Fedoseev

All credits go to Anthony for sharing his answers openly. Please forgive me if I forget anyone who contributed. If anyone knows any answers which Anthony is not sure about or doesn't know, please help. I will also try to do my best

Bad Dobby, these are the correct answers which are verified. So you need not inspect more on these questions. For 19 if you want go google it

it doesnt come up with something usefull

I know but there are posts on wikipedia. Go find it. I cannot search it for you and give the link Im sorry. Or else try it on your analysis board.

Read all the two discussions, the answer is there. (The other discussion is below the questions.)

i went to his videos on twitch, but it doesnt say the date, just "2  months ago"

and there were 2 hats in all of the 2 months ago videos

I don't know if he changed hat during the same day but I also saw 31 oct in a stream where he wore the chess.com. He may have made 2 streams that day...?

it doesnt say the date

anything from 2 months but less than 3 months ago will say 2 months ago
