Tricks needed: long jump (right name?). Sometimes B will fall off after pushing the first ball so no trick is needed. See the video for the trick (used once near the start). Spoiler: Video solution
I've given this 5 because I found it fun but, unlike my very talented friend @delator77 , it took me some time to figure it out. I'm unfamiliar with the long jump trick but once past that things were easier. The last move had me foxed and a clever piece of timing I thought. Thank you for sharing.
I had to keep starting again because I realised I should have done something earlier, . Some fun and unusual ideas, and lovely to see a move I haven't seen for ages, Spoiler [the long jump, I think it was @DonGRowe used to use it, ]
