Claudius briefly regrets whatever came up that prevented him from practicing weiqi with Qi Yan and learning tricks to surprise Lan Wangji. The zombie attack might've been what came up -- but that's something else time can take care of. Claudius has the expectation of enough time ahead, and enough weiqi matches, to find a better strategy than wildly overconfident bluffing. He can still try the bluffing strategy a few more times before seeing Qi Yan. "With pleasure. I hope you're prepared to be surprised," Claudius says, with no surprises in store.
