If the Kyokushin karateka had little sparring matches or competition history and the boxer do, then the boxer has an advantage, karate fighter has advantage if the other way.
The thing is the rule would likely to restrict elbows, knees. Kicks are good at their range but once your get past that, he can't really kick you without getting knocked down.
The game strategy matters here.
The one that knows what he is doing, and has some luck, will win
Now, if a boxer lands 1 clear combo, with 4-6oz gloves or something, you are a goner
As long as the Karateka is fluid and adaptive, and takes advantage of being able to use kicks as well as hand strikes, he should have the advantage. But anything can happen in a fight. If either opponent has poor defenses the other can capitalize and turn the outcome.
Full contact if both of you train.karate by leg kick/body kick/head kick.
Which one has a better chance of winning with a month of prep and training time?
The fight would be in a Boxing ring but with Muay Thai rules and would go for 5 rounds of 3 minutes.

This is a fight I'm having with a friend soon, which one do YOU think will win? I'm just polling and looking for friendly opinions. I'm not trying to prove which style is better either. Thanks for your time!
