We created a CTF to celebrate the World Chess Championship 2023 between Ian Nepomniachtchi and Ding Liren:

Key

  6q1/p1k5/1pb3n1/5pBP/3R4/P3P3/6P1/3QK3 b - - 0 32

Ciphertext

  l63B0cPnh8X2gtXJlriG5oqIgNaQwpvFo9eS4rPkl9HByZ2j0re35IHi1u6erufR1b2gmJI=

Flag is in the format CTF{HERE_IS_THE_FLAG}

We will publish the solution when the new World Chess Champion is crowned, which will be Sunday, 30 April at the latest.
