I've found that fighting square has more disadvantages. I suffered from Tyson syndrome when I first started. Peek-a-boo this peek-a-boo that. Started visiting this forum and read about the advantages of having a more "narrow" stance. Straight away I noticed the power in my rear hand improved and that my jab had more reach. I've also found it alot easier to defeat a squared opponent by simply circling to my left setting up the jab to the solar plexus. I've found that squared up oppenets tend to be left hook happy fighters who need you to move in a straight line jabbing so that they can slip to your inside.Their gut is wide open when you circle left and they cannot gain leverage because they are constantly trying to re-arrange their feet. Even if you do find yourself straight in front of them all those jabs to the gut should have taken their mind off slipping just that little bit to help you unload a straight right to the head that is neatly hidden behind your left shoulder.
