An intelligent Hulk simply leaps off to grab some kryptonite and shoves it square in Superman's bung.
They are evenly matched on brute force... Hulk (the smart one) is far far more intelligent.. he also has a less stringent moral code... whereas Superman has a glaring weakness in regards to kryptonite... seems like a pretty clear win for Hulk.
You're cherry picking the best version of the Hulk to face the standard version of Superman. There are versions of Superman that don't have a vulnerability to Kryptonite, plus the 50s version who is so ridiculously overpowered that he could practically do anything. Plus the Hulk is from a different universe where Kryptonite doesn't exist, so he has no way of knowing about it.
Then even if Hulk somehow figures out that this substance that he's never seen or heard of is the key to defeating Superman, how does he get away from Superman long enough to find or make some? Keep in mind that Superman is (at the very least) almost as strong as the Hulk and much much faster. Hulk jumps away to find Kryptonite, Superman zips under him and knocks him into space, game over.
I've never heard of a story where the Hulk survives the core of a star, but even if he could I don't know how he could escape it. And even if he could do that, Superman could just leave him in deep space to ineffectually thrash around.
