It's not a big event, but as someone who grew up during his world championship tenure I'm always happy to see Anatoly Karpov in action - at least when he's playing pretty well. He's 67 now and hasn't played as a true professional for nearly 20 years, and his openings are fundamentally subpar for a player of his level, and yet he can still hold his own against strong opponents in games with a short time control.
Here's a report on his latest success, a close victory in a four-player event whose other participants were Anatoly Vaisser, Ljubomir Ljubojevic, and Eugenio Torre. Vaisser made it a surprisingly close race, while Torre's result was disappointing, especially considering his fantastic result in the 2016 Olympiad. (Torre finished with a 2836 TPR, taking the bronze medal on board 3.)
