At first, we will present the result of the main line of Joachim's Ko-Semeai itself. Several issues, where both sides can go wrong, will be explained later, as well as our justification for choosing the very special moment for starting the ko ( 960).

FLAG 0a: ( 944)
White will win the main line of Joachim's Ko-Semeai, with the ko being started "late" (i.e. when her centre group has five liberties left).

FLAG 0b: ( 957)
Black could win the game, only if he had at least one ko-threat more than White.
