The Sun Crusher was then placed deep inside the poisonous atmosphere of the gas giant Yavin, where it was thought that the incredible atmospheric pressures would render the craft inaccessible. However, the young Kyp Durron, now a Jedi adept at Luke Skywalker's Jedi academy at Yavin IV, yet unable to control his hatred of the Empire and influenced by the ancient Dark Lord Exar Kun, retrieved the Sun Crusher from the depths of Yavin. He then destroyed the Cauldron Nebula along with most of Admiral Daala's fleet.
After Kyp Durron destroyed the Carida system, Han Solo and Lando Calrissian came looking for him and chased Kyp to the Core Systems where they found that he had also destroyed a major starship construction yard and a weapons depot with it. Han then found Kyp and distracted him while Lando attempted to shut down the Sun Crusher. However, Kyp used the Force to restart it and threatened to destroy the Millennium Falcon with one of the supernova torpedoes. At this moment Exar Kun was destroyed by Kyp's fellow students and Kyp realized what he had done and surrendered to Han. To redeem himself, Kyp had to destroy the Sun Crusher. He destroyed it during the Battle of the Maw Installation, where it was sucked into one of the Maw's black holes along with the Death Star prototype. Kyp survived by escaping in a message pod, though he suffered serious injuries in the process. Durron used the Force to slow himself almost to the point of suspended animation and crammed himself into the tiny message cylinder.

I don't think so. Kyp is most certainly one of the strongest force users ever. In one of the NJO books there is a passage to suggest that Anakin Solo is even stronger than Kyp at that point.
The part you are referring to is in Star by Star. Kyp reached out and felt a presence more powerful than his own. It seemed that was more towards raw power than over all ability, as Kyp is far more experienced and had has much more training. I definitely see them winning this fight though.
