Let me tell you where I am getting at. In an attack, I think the probability is high that the attacker will be bigger, which is why I ask about relative sizes when someone tells me about a KO with a strike to the solar plexus. It's my guess that it is unlikely that person getting KOd is 30 or more lbs heavier than the striker.
Bigger people tend to attack smaller people, not the other way around. This is not to say there aren't lots of whacko small people out there that love to mix it up with people there own size or even larger. It is just that if you look at the odds of being attacked by a weaponless, lone attacker, it is highly likely that he is bigger. 20 lbs, or 30lbs might be the minimum.
Against someone actually striking you on the street, someone who outweighs you by 30 or so lbs, it is my strong belief that many traditional karate applications (step back, block, strike to the abdomen,) are just really bad fighting for at least four reasons.
1. By stepping back, you are bringing yourself out of range, making effective counterstrikes from the stance difficult. Best to go off to the side and stay in close.
2. By not stepping off the line, you are not avoiding the attack, and you must block with great power to move the strike off its trajectory. (Again, best to go off to the side)
3. By choosing a single counterstrike, you are putting all your eggs in one basket. You are not allowing for all sorts of things going wrong and in a fight, you should expect Murphy's law. (It gets blocked, it doesn't hit hard enough, it glances off a twisting body, etc.)
4. By selecting the solar plexus, you are picking a target where it is hard to hit (a rotating body goes with a hooking strike) and if you miss, you hit all sorts of targets that have no value (sternum, upper ribs, pectorals, etc.)
I recognize that sometimes the solar plexus is a great target. If someone is standing still and grabbing you, it might be easy to hit. (Funakoshi wowed the Japanese establishment when in front of a large crowd he instantaneously dropped a big young Judoka who grabbed his lapels for a throw.)
And I recognize the value of hitting someone in the upper abdominals in certain situations. If he is stationary, and not too much bigger, and not in great shape (big belly), you can really knock the wind out of him. This can be a great exit strategy because it is awfully hard to chase someone when you are sucking wind.
But against a right hook to the head from a big attacker, (probably the most common kind of attack) the kinds of defensive applications practiced in many karate schools are, IMO, prescriptions for getting badly hurt.
