Jorge Cori Tello and Alireza Firouzja started analysing on one of the boards opposite the Chess Cafe. Firouzja told he had played the Budapest in blitz games before, not in classical chess. 'But I think it's very interesting.' Cori had chosen a sharp line against it, 'but in fact I didn't know it was that sharp!' he laughed.
In this position White could have held the Drimer rook in its cage with 11. Na4 instead of 11. Bb2. 'But then I can just play 11...Bf8 with a normal position,' Firouzja said.
Later the position became extremely complicated.
Instead of the game move 25. Qc4+ here there was a win with 25. Ng5!! Rxg5 26. Qh4 f4 27. Qxg5 Bxc5 28. Bc4+ Kh8 29. Ke2 and Black can't make any progress, e.g. 29... Bxe3 30. Rd8. A line pointed out by Firouzja's father, who claims he can't play chess - but he did spot the line on his mobile!
As it went, White could not get enough counterchances and lost.
