English is not my first language but for clarity perhaps the title should be:
Go grandmaster Shin with a two-stone handicap defeats AI KataGo

Idiomatically a handicap is a disadvantage not an advantage. So if Shin had two extra stones, KataGo had a two stone handicap.
No. It’s not my first language too, but your version sounds odd. Usually you put an action first and only then the details
Trouble is, from the existing title it's not clear who had the handicap. So the poster is right to try and fix it.
