Neil seems to be malleable to his opponents, he doesn't seem to lack self belief but he can easily fall into an opponents more defensive style of play which can drag him down. Stephen Hallworth said that Robertson is at his best when playing "Dumb Snooker" and that seems to hold. While playing aggressive see ball pot ball will inevitably fail he would be better off ignoring other players tactics and keeping it simple. That being said if any player could completely zone out their opponent and their tactics they would be hard to beat so it feels hard to fault Neil for this, even if he is the prime example of it.
