Some aspects of two-on-one pursuitevasion

$\text{Pursuit}\text{evasion}$ problems featuring two pursuers and one evader are examined in the context of simple vehicle models. A type of coalition tactic which exploits the difference between open-loop and closed-loop conjugate-points is introduced and illustrated. The approach would permit identification of some two-on-one team tactics opportunities from families of one-on-one differential game solutions.
