"content": "Sunk at b10 — the ship from b10-d10 is 3 cells long, confirming it as the Cruiser (size 3). Now only the Carrier (already fully hit), Battleship (4), and Destroyer (2) remain afloat.\n\nThe Carrier (b3–f3) is still not marked as sunk but must be — all five cells are hit. Focus now on finding the Battleship and Destroyer.\n\nOnly a few unknown cells remain. Look for clusters: e10 is unknown and adjacent to d10 (sunk part of Cruiser), but e10 is likely free. Try e10 next, as it could be part of a horizontal or vertical ship.\n\n<guess>e10</guess>",
