Opponent’s options: RADIATOR m3, ADROIT 1j
Scoring options: Many 20 point options with blank, TRIG, STIR, etc.
Setup potential: Yes

In this position, your opponent has two standout options, and you need to block both of them. While there are a few good plays like VINAS, it’s important to note that these give your opponent decent scoring on row 1. The best option is VIRUS, blocking both spots while giving your opponent very little next turn and leaving yourself out plays.
