Kalaiyalahan, Akshaya vs. Kalavannan, Koby - British Chess Championship 0-1

In the British Chess Championship on July 31, 2024, Akshaya Kalaiyalahan, playing with the white pieces, moved her rook to f1 against Koby Kalavannan. This move threatens a material gain but overlooks an opportunity to develop another piece more effectively. By playing Rf1, White misses a chance to capture material and fails to exploit a superior threat. Furthermore, the move disregards a better option involving the knight and allows an opposing piece to potentially drive it away. Despite these drawbacks, the rook's move to f1 contributes to White's active play on the board.
