Alpha led GREEN 1 and must win this trick for the task to succeed. However, both Gamma and Delta have communicated that they hold GREENs (Gamma’s highest GREEN is 8; Delta’s only GREEN is 3), so at least one opponent to Alpha will be able to follow suit. Since any GREEN higher than 1 will beat GREEN 1, Alpha cannot win this trick no matter what I play, and rockets would also prevent Alpha from winning. My only legal choices are GREEN 2, 7, or 9. Playing the lowest GREEN 2 minimizes harm: it keeps higher GREENs (7, 9) for future control/drain plays and slightly reduces the chance that I end up winning the trick compared to playing higher GREENs. It also aligns with the plan to preserve higher GREENs for later when trying to void teammates before any future GREEN 1 lead (though that window has closed here).
