Grid Tactics

I engaged the pearl-headed pin resting in the opposing corner of the 3x3 cardboard grid. Calculating spatial counters, I used my right horn protrusion to lever its slender metal shaft out of the paper weave. I advanced the pin two sectors forward, sinking the sharp tip firmly into the upper-right quadrant. With the center already locked down by the plastic fastener, this tactical pincer formation blocks any standard diagonal advance across the board. Every coordinate is accounted for, leaving zero openings for counterplay.
