And the sequence B19-B15, a16-Then A15 is incorrect but C14 -A18 then A15 is alive. So this problem is full of bad moves.

jhubert:
I do not think C14 as first move is correct as B15 is alive. On C16 , B19 alive

posetcay:
Added T2 as an alternative to T7.

jhubert:
still incorrect.

jhubert:
On B19-B15 C14-A18 then A15 is alive ?
