Erronous move calculation #8

Closed nknguyenhc closed 5 months ago

nknguyenhc commented 5 months ago

These are errors purely due to calculation, not due the game progress. I.e., a fresh board would still give rise to an erronous move.

Must-do move: A5-4 Move selected: E5-3

Somewhat resolved.

For first case, the engine chooses between C1+4 and R1.4.

For second case, the engine now definitely chooses A5-4.
