A couple of general questions to everyone

[Bigwig]

I play the $20 NL Hold Em games on Stars.

1. Early in the game, sit and wait for a monster, or play a few marginal hands when you've got outs with small bets into you?

I've been thinking, as I play more, that early on you should be VERY patient, and wait for monster hands. For example you call with T9s, and the flop is T, 6, 4. Now, I'll bet this if it comes to me, and maybe call a small (say, half the pot) bet, but is it really worth it? If you play too many of these kinds of hands aggressively, you can get burned. What do you think?

2. 4 players remaining, A and a small card unsuited. Raise or call?

I've been calling lately, although I used to raise before because it is a favorite against three random cards. I've found that calling makes players think you don't have an A, and you can get a little extra action that way. Plus, when someone does call your pre-flop raise, what kind of chances can you really take when an A hits? Many players will go all in, and that's a call you can't make. Thoughts?
