Chattogram Cube Open 2023

In the exacting discipline of the 3x3x3 Blindfolded solve, the margin for error is razor-thin because a single mistake over three attempts dismantles any chance at a recorded average. At the Chattogram Cube Open 2023, SM Abeer Ullah mastered that unyielding pressure to secure the title with an average of 1:04.16 and a sharp best single of 57.23 seconds. Competing against a field of 15 solvers who had to balance rapid memorisation with flawless execution, SM Abeer Ullah stayed clean across the board. The performance stood as the defining display of mental endurance across a weekend where precision under strict three-attempt formats dictated the podium.

The competitive action unfolded on September 22 and September 23 at Presidency International School in Chattogram, Bangladesh.
