yes, against a weaker player you can play a more "risky" game - that is, risky in theory because it leaves potential vulnerabilities, but not very much in practice because you can be fairly confident your opponent won't capitalize on them. Nigel actually did that to me once; in a game that he was already winning he deliberately left a difficult lane open to give himself a chance at one last bingo, knowing that I would not see what he was up to, and had the satisfaction of bingoing out in a spot with four of his seven tiles constrained, and picking up a nice bit of extra spread.
