Hello,
Sorry for replying lately, the problem and answer are as follows:
Problem
Black: G3c
White: K2a, P3a
Black's hand: 1L, ?P
Questions: How many pawns are needed for black to win?
Answer
4 pawns are needed.
The moves are:
L*2i S*2c P*2b K1a P*1b S1b P2a+ S2a P*1b K1b L2c+ K1a P*1b S1b +L2b
(15 moves)
Thanks to everyone taking part in this problem. As mentioned last time,
my idea about this problem came from Patrick Davin's tsumeQ&A page.
Sooner he told me that his diagram was referenced by the original problem.
Thanks for his remark. But I learnt that very lately.
By the way, in the answer, L2c+ can be replaced by G2c and the same moves
follows. So is this problem imperfect in the sense that it can be solved
by more than one ways? How about if the G on 3c is replaced by +L?
best regards,
Kai Wan Leung
