Booot kicks into high gear, wins TCEC S21 L4

After having a rough start in the Qualification League, Booot (ELO 3391) finally showed its potential. It won convincingly League 4 of TCEC S21 with 17,5/22 – 13 wins, 9 draws and no losses. Booot finished a full point ahead of the rating favorite Halogen, and three points ahead of the QL winner Koivisto.

Booot, together with Halogen, Koivisto, and the debutant ClassicAra have qualified for League 3. This will be a key league for the engines, as finishing top 4 will give the right not only to promotion, but also to updating the programs.
