Puzzle 1059: on the sixth move (with opposite kings) multiple wins are possible apart from the expected 38-32. My 38-33 (29x38 43x32 etc. try) was deemed wrong. I didn't check 42-37 and 47-41, but tho…

Puzzle 1542 can be solved in two ways: the solution as is, but also 1.33-29! (24x33) 2.38x29 (22x24) 3.34-29 (24x33) 4.42-38 (33x42) 5.32-27 (21x41) 6.36x38 (26x37) 7.48-42 (37x48) 8.40-34(48x30) 9.35…

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

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

It is also possible to change the move order: 25-20, 34-30, 43-38 etc.
