The hard part is tempering arrogance and aggression with calm prudence.
Drunkenness and the right music can definitely help the with the first two (often at the expense of that last two).
i agree that there is much to be said for calm prudence and careful calculation, however we are not grandmasters.
I love to play chess when I am drunk. It makes me feel powerful. This movie scene from the classic Jackie Chan film "The Legend of Drunken Master" describes how I react on the chess board while I am drunk. I keep coming at my opponent fast and strong and I don't stop, no matter how hard they hit me. If they try to be sneaky, I just dodge and counter.
