In this case, the best solution is BY o2, setting up IXIA. While your opponent can block, doing so completely cripples their rack, allowing you to go out in two. In this situation, your opponent is best off trying to block with BYTE, allowing you to play RIA a8 and XI. The optimal route is BY o2/BYTE o2/RIA a8/BEE o1/XI k10, resulting in a route of BY = (21 – 10 + 12 – 18 + 31 + 4 = 40).
