At the begging of a sng i like to play 9 handed, and definitively 22 is not a hand to play there (for me). Farther (like 5 players) i would play the ducks only if my chips stack is quite big in relation to the others, and i´m in middle or late position (remember that always the situation matters: your opponent´s playing style, your position at the table, your stack, your opponent´s stack, the
tells, etc.).
Just define your playing style and think about what you should do with those ducks depending on then situation, because for some aggresive players the 22 are a monster, and for some tight players they are crap. Just try to mix up.
