Why this move works
The answer is h3. Reading to the end gives a final +14, 2 ahead of the next-best. Here the move that flips the most now (h3, 6 discs) also happens to be best.
Even so, in othello the biggest-flip move is not always best. Always confirm by reading all the way to the final disc count.
