Keith got second place in the final.
In this game, my 12th played to transpose into a Maróczy Bind. The pawn structure where White places pawns on c4 and e4 with pressure on d6. This could have worked if I found the strong, Stockfish super accurate 16. Nd5 cxd5 (16... Bd8 17. Bxd6 Re8 18. Nf4) 17. exd5 Qxa2 18. b3 Qb2 19. Bg3 Qf6 20. Qe4 a5

Before choosing to be passive with my 18. b3 I made half a page of notes ending with the words 'Oh dear'.

There followed twenty effortless moves from his pieces threatening mine while I struggled to find safe squares for them.
