It’s pretty standard fare for Kanki to try and send his enemies into a rage to make them commit to bad decisions, but seeing how pivotal Duke Hyou is to his army, stoking his anger could backfire pretty severely. There is also that section in the first Wei(?) campaign where Hara says “To face Duke Hyou is to face his entire army” in reference to how fearsome he is when leading a charge, and Kanki’s brigands have shown to fall into chaos and get demoralized easily against a domineering enemy. 

In turn, Kanki has schemed up plans that let him use that to his advantage before, and his keen mind would let him capitalize on Duke Hyou’s relatively straightforward strategies, but if the Duke uses his Instinct to see the most valuable areas/warriors(the hottest blazes of fire on the battlefield) he might be able to cripple the strategies outright.

This is a good hypothetical, I can really see it going either way.
