Chris,
I have heard it stated that high handicappers can't fully appreciate the strategy because they aren't good enough to make the decisions that matter. Most time, they are happy to aim at the centre of the green, which gives the greatest margin for a push/pull.
I don't agree with this point of view, but in the case of the dangerous par-3 (like Greg, I'll assume its a short shot), the high handicapper (like the scratch player) has the opportunity to look at the pin location and make a decision whether to go for it and risk disaster, or play safe, and as long as he doesn't short side himself, could still salvage a bogey (if not a par!!). Because even the high handicapper is likely to have a short iron into the green, there is some degree of confidence and decision to be made.
