If Blue plays first in any of the marked cells, Red wins with perfect play after this move.
In view of that, Red might like to try the same move after this blue opening. However, it is currently not known who wins if Blue plays one of the marked cells next. (All others are losing for Blue.)
If Blue in fact has a winning move in the previous position, Red can instead try one of these three moves (of which two are mirror images of each other). All others are losing for Red.
Regular Y / Size 10
Regular Y / Bent-27
This board (on which the pieces are placed on the intersections) should be within reach for computers, but no results are known so far.
Master Y
In Master Y, the first player places one piece on the board, and each subsequent move consists of placing two pieces on the board.
- the red marked hexes are losing first moves
- the blue marked hexes are winning first moves
Master Y / Size 2
Master Y / Size 3
Master Y / Size 4
Master Y / Size 5
Master Y / Size 6
Master Y / Bent-27
Again, status unknown but presumably within reach for computers.
