If "Opp. parity" is "Diff", then go up the other column instead." So yes my bad I think you have full solution.

Jun 25, 2020 at 4:47 comment added Vlad Barkanass Yes i see my mistake, in my solution when taking stone ithink I change parity for my oponnent so I think fixing my solution you need to: calc openent party and find in 3 stone below if their is a losing game for this parity
Jun 25, 2020 at 2:30 comment added Bass When there are 5 pebbles left, and you have an odd number of pebbles, opponent also has an odd number of pebbles. That's why you look for the losing position in the same column. You can always check the result by playing out all the variations: Let's say we both have 5 pebbles, so there's 5 left. I take 1. If you take 1, I take 3 and win. If you take 2, I take 3 and win. If you take 3, I take 1 and win. So 5 pebbles with odd is winning.
