Large but killable
Larger spaces are generally alive, but the vital point still matters. Five-point shapes (the knife-handle five, rattan-handle five) DIE if the attacker plays the vital point — they cannot make two eyes. The symmetric six-point flower shape (rabbity six) also dies to a centre play. Only at six points in a line (straight six) and above is a shape unconditionally alive. The rule of thumb: odd, compact shapes often have a single killing vital point; long or square shapes live.
