[stigmata]

Just to add that Ed is probably right sometimes..... (I haven't read the article either). Some games become increasingly tilty and over-aggressive when they go short-handed, and you therefore have to make read-dependant adaptations. Other short games play much more like full-ring where the first few players have folded, and you therefore are playing a somewhat similar defence strategy.

For example, someone who was stealing on the button with 40% when it was full-ring is now stealing with 60%, and you can therefore widen your defense/3-bet range.

I think the confusion comes from the fact that you are NOT widening your defense range purely because the game has gone short-handed, you are widening your defense range because some players are now stealing with increasingly trashy hands.
