Dornelles, Marcio Neron Camargo vs. Fier, Alexandr - Manaus Chess Open 2023 0-1

In the Manaus Chess Open 2023 on October 12, 2023, during a game between Marcio Neron Camargo Dornelles playing as White and Alexandr Fier as Black, White played the move Rb3. Regrettably, this move missed several critical opportunities. It failed to threaten the opponent or reveal a potential attack on an enemy piece, which could have added complexity to the position. Furthermore, it overlooked a superior chance to address an existing threat effectively. In this context, Rb3 also didn't seize a winning tempo or provide a better escape from the opponent's attack, which could have improved White's position. While the move did defend an attacked piece and made that particular piece well-protected, it missed an opportunity for superior protection for an underdefended piece elsewhere on the board. Ultimately, it failed to force Black into a more favorable move, representing a missed opportunity for White to gain the upper hand in the game.
