If the shot it flatter than a normal house shot, I would assume you would want to play straighter, not necessarily further in.
Extreme launch angles on a flatter shot than one is used to can lead to difficulty in maintaining a consistent reaction. Playing straighter and treating it more like a sport shot should help until a defined break point is established.
This only applies if the shot is flatter. Honestly, I would treat it like any other shot you don't know about. Try not to walk in with preconceived notion of what to do. Just pretend you are in a different house for the first time.
