As Apollo17 said, power and strategy both are equally important in battle. But strategy is made when you know your as well as your opponent power. If you don't know the power of yourself then how you can execute the strategy then.
In this case, Hikaru never considered the awakened dragons power.
He made strategy for both longinus and unawakened dragon. If lui would not have helped drum awaken dragon then Hikaru's strategy most likely would have become successful. At the end of the day, Hikaru's Strategy was full proof but with less knowledge of the opponent( drum). And lui was also a factor due to which Hikaru's plan failed.
I think Hikaru underestimated his opponent. In drum's case he might have thought that the power level of dragon is similar to when drum fought Hyuga and in Lui's case he never considered that Lui can also make a Strategy.
I don't think Hyuga is the type to make strategy and Hyuga is most likely going to attack head on.
