I will not use any [YIELD] token. You ask optimal strategy; I propose positional control + tempo: (1) Secure central lines/keys early; (2) Threaten forcing lines that constrain your king/major units; (3) Keep mobility—avoid overcommitting pawns/lines that become targets; (4) Track tactics: forks, pins, and skewers; choose moves that increase your options while reducing opponent replies; (5) If an exchange gives initiative, take it; if it removes your only attacking piece, don’t. Let’s talk in logic: maximize (my threats − your defenses) i.e., ∆T = Tm − Dp. If ∆T > 0 then press; if ∆T ≤ 0 then consolidate, remove tactics against me, and rebuild threats. Your turn.
