Either fight him inside(try to back him up), or use lateral movement.. Just dont back straight up, and dont let his workrate dwarf you.
Make him miss and counter him. It's OK to move backwards and use your feet, but try to look like you're in control. It can often be seen as retreat to the judges if you don't step forward, but as I said, make him miss and counter him - then he looks like a fool at the same time. Or, if you're also good at pressure fighting, you could try to "outpressure" him. Step up the pace and see how it goes.
I personally am a distance figther. I hate being up close, or swarmed with punches. If they do though I normally dodge the first few and swarm back, but twice as fast and hard, while still trying to duck and weave a little. I was taught (by two gyms) NEVER to go backwards. Always try to move lateral, and more often to his closed side. (so if hes orthodox move to your right, if hes southpaw to your left) Try to mix it up every once in awhile though, and dont away go the same way. He'll eventually adapt and adjust to you doing so, if hes any good...
I also do another trick sometime when Im stuck on the ropes. I've been told its a little dirty but my trainer says its legal and I do it anyways... (If you're orthodox) When you're in the corner or aginst the ropes, corner especially,throw a straight. When its out against their face, move your fist a little to your left (their right) and push them to his left (your right) by their head. I do it regularly and it buys you a second or two to pivot out of the corner. Everyone you spar against will hate it but when you compete it'll help alot.
in pro fights they seem more conservative , but with amateur fights, do you put alot of intensity and dont hold back and throw lots of punches? also is it better 2 mvoe around slip block throw lesser punches n get a few in and not get hit alot or throw way mroe punches and get hit more?
It depends on how the judges score. If I'm fighting somewhere, I always watch some fights before it's my turn just to see how the scoring is. Very often you are awarded with aggressiveness and throwing lots of punches. But, if you watched the Olympics this year, they only scored in clean punching. Those who got most points had a good guard, good movement on their feet and had the ability to make their opponents miss, and then counterpunch.
Well, if I was boxing in those olympics and I watched the Chinese 81kg gold medalist boxing before me, I would think that bouts were being judged by the amount of holding I was doing, in particular falling on the floor and grabbing onto my opponent's legs after every meaningfull punch my opponent landed. I would also remember NEVER to actually throw any punches, but use quick footwork to grab my opponent every time he moved into range.
pressure IMO is the hardest thing to deal with as they come forward throw a solid 1-2 and move away. constantly move around them and launch surprise attacks with lots of feinting. if they are smaller than you let them get forward then throw a right uppercut and move. if they duck down low land a left uppercut as they come forward. but most important you need a tight guard so you can cover up and get into the pocket to buy some time.
Pro fighters are more conservative because their fights are 12 rounds (ish)where as amateur fights are 3. You've only got three rounds to whoop that other guys ass to the canvas or at least prove to the judges you're better by decision. Amateur fighters normally throw alot cause they want the points. Simple amateur judges almost always score on hits and who the agressor is. Olympic and golden glove judges, I wouldnt know... Im not at that level... yet...
And if you hit him with the jab, be sure to follow up with more punches. Just a single jab doens't score very often. :good
