my new fuseki
4x4 square is always between center and top right corner


each stone has backup alternative in case someone will try to prevent it




so, I always would have same shape in same asymmetrical place in every game
it may continue to be clearly distinguishable from opening to endgame
I no longer need to think how to rotate or mirror the board to make 2 different games similar

for those who want the math here is one way: count 19 across the first lines then subtract 4 for doubled counted spaces. Do the same for the second lines by counting 18 across each then subtract 4. Add the remaining “inside corner” points which are 3 per each corner. The result would be 19 x 4 - 4 + 18 x 4 - 4 + 3 x 4. Knowing the properties of multiples, 19, 18, and 3 may be added since they all are multiplying by 4. So make that 40 * 4 - 8 for 152. The inner circle is left as an exercise to the reader.

Fun fact: ChatGPT totally sucks at this. Although it can see the picture, and correctly describe the layout of stones, it had an epic fail at doing the calculation :squinting_face_with_tongue:
