15 Year Old Ukrainian Anastasiia Hnatyshyn leads the Women's European Chess Championship with one round left - She's gained 205 ELO this tournament
I haven't seen anyone mention this ridiculous tournament performance from a 15 year old. She's at 8.5/10 with a .5 point lead going into the final round. I don't know how ELO works exactly but she's gained more than 200 ELO points through these 10 games, skyrocketing from 233rd in the world to 21st among women with a live rating of 2456. Wow.
