Pairstrike Garden

Original19×19 pair-capture strategy with the basic center opening: Mint starts at J10. Alternate an empty intersection; five or more connected own stones in any straight direction wins. Bracket exactly two opposing stones against an existing own stone to capture a pair in any of eight directions. Remove all simultaneous pairs; five captured pairs also wins. Captured cells can be reused; no self-capture or capture cascades. Full board without winner draws. Basic rules without the optional tournament opening restriction.
