it's ok,thanks you the difference it's after 1. 21-27, and so on,he can take 16*27 instead of 23*32 because of 21-26. and I didn't see 13-18 and 08-13 while white take 5*37

33-29 is also good 24*33 *33 *24 34-29 42-38 32-27 and so on and it's more beautiful

1 ... 21-27 is also good

after 27-21 and 33-39, the move sequence 30-34, 48-43 and 42-38 also lead to a winning position.

28-22, 38-32! (27-21 40-34) is also winning
