Opponent’s options: ZA/SAZ row 10, AL 15b
Blocking options: IN/ION row 10, OBE n7
Setup potential: No

Although it never feels good to allow your opponent to cash a blatant setup, blocking is just too costly, and you’re better off simply going out with IO/FINI in the next two turns. OBE just allows your opponent to score over 50 points in two turns without much compensation, while IN/ION spents your N you need to block the setups in the bottom left (blocking with NONI). IO is best for 13, as the 5 point play only nets 3 points from ZA instead of SAZ.
