When a full table becomes short-handed at critical junctures in tournaments, you have a situation where the large blinds are coming around twice as fast, and also there could be only 4 or 5 players playing at a table. Waiting for the "nuts" to come is a bad strategy as your stack will get eaten by the blinds. Thus, the situation dictates that you must play more aggressively.
Second, Aces and Kings have more worth at table with less players than they would with a full-handed table. High cards become more valuable. Thus, this also enables you to play looser than you would normally at a full-handed table.
Playing draws at short-handed tables is generally disfavored. Generally, not enough people will call to make the draw profitable.
Of course, position, your opponents tendencies and game situations are all still relevant factors in deciding how loose to play.
One view was that these starting hands were acceptable in these situations.
Any Pairs 55+
A10 or higher
KQ
QJ
JT
Others said just about any ace was acceptable to play as it was unlikely an opponent would have one. But I think experience should be your guide in playing weak aces. This view also approved of K9 or better on the same theory.
There are many different views as to how loose one can play. Much will also be dictated by the size of your chip stack.
One common theme was to always raise when you went in; no limping so you put the burden on your opponet to call or fold. In any event, your raise and his response will give you valuable information.
