Live in England. I played a lot as a child, reaching a rating slightly over 150 BCF/2000 ELO, but I haven't played seriously since going to university. (Mostly because I'm not particularly driven to compete, to try to defeat an opponent; at uni, I was able to find some appealing co-operative activities.) I like the world-vs-GM games here (perhaps due to their partially co-operative nature), and have made some (minor) contributions.

Lambda: What a bizarre puzzle. A position with one single, obvious forced move.
   Jan-06-22 Ulybin vs A van Rijn, 1993 (replies)
Lambda: 22. Bxg6 is actually inaccurate, as 22... Nxc3+! creates very unclear complications. The solution to this problem needs to be 22. Rxg6! after which the threat on g7 and restraint of the bishop there, coupled with a winning attack on the light squares if 22...fxg6 23. Qe6+ gives white

Lambda: I loved this puzzle, finding such a beautiful move is very satisfying. (Like most, I started with Rxh6+ and Nf6+, but that didn't seem to be going quite right.)
   Dec-12-21 Carlsen - Nepomniachtchi World Championship Match (2021) (replies)
Lambda: <Let’s take a hypothetical situation. Let’s say we’re at the last round of the upcoming candidates, Karjakin lost all chances to qualify and there is an American and a Russian that are tied for first. Karjakin is facing the Russian that is tied for first> Can't happen. ...
   Dec-09-21 M Gerusel vs Lombardy, 1957 (replies)
Lambda: Saw the first three moves, also saw that 15...Nc5 16.Qb5 Na5 could be played, but wasn't quite sure what happens after 17.Nd2. In the end, it turns out that 17...Rxd2 18. Kxd2 Nab3+ and 19... a5 imprison the queen and it gets picked up by Bd7.
   Dec-07-21 Nepomniachtchi vs Carlsen, 2021 (replies)
Lambda: <Every decisive game in a world championship match must have a blunder somewhere, the only thing that varies is the depth.> That's not true, you can lose a game through a series of small errors. There will inevitably be a point where a 32-man tablebase changes from "not lost" ...
   Dec-01-21 J A Torres vs R Gonzalez, 2000 (replies)
Lambda: The editorial goal doesn't actually quite parse. There is only a 'best sequence of moves' in cases where the other side has only one defence they can try, and in positions where you need to see a lot, this is rarely the case. Normally you start off needing to see one or two moves, ...
   Nov-28-21 Saidy vs J Becerra Rivero, 2005 (replies)
Lambda: I don't normally get anywhere near Sundays, but that one was easy. You have to briefly consider 25.Nxe4 and 25.f3 too, but even just 25...Rh1+ in both cases leads easily to a decisive material advantage, even if you don't continue the attack with 25...Qh8.
   Nov-27-21 Kudrin vs H A Machado Jr, 1988 (replies)
Lambda: 23...Qf4 24.Bxg7 Kxg7 25.Rf5 Qh6 26.Qg4+ Qg6 27.Rg5 Bc7 28.a5 Nc8 29.h4 [DIAGRAM] White is down a queen and a pawn for a rook and two pieces once queen and rook are inevitably exchanged, but nevertheless has a winning long-term attack.
   Nov-25-21 E Prandstetter vs Ftacnik, 1986 (replies)
Lambda: Saw up to 46. Rf8, but then I couldn't find spot the winning of the queen after 46... Kg7.
