Opponent’s options: m2 parallels, l12 parallels
Candidate plays: QI, QOPH, WHA, OX
Potential plays on next turn: Same plays

Subgoal: Outscore your opponent: you won’t be able to go out first (in all likelihood), but you can achieve superior endgame timing and maximize the use of your high point tiles.

Resolution: In this position, QI is clear. QI allows you to get rid of the Q, preserving flexibility as well as endgame timing. Making this play will allow you to make out in twos and high scoring options against an opponent who will have a very difficult time scoring on this board after they use their M.
