1. Your bets preflop should be of standard size. 2.2 up to 3 is fine. Keep them the same though whether your hand is 5,6 suited or AA.
2. Never limp into an pot which has not been raised. And never raise unless you are prepared to call 1 x standard re-raise (e.g you make it 150 to go and someone behind makes it 300) to see a flop.
After the flop .. depends on your position, cards, number of players seeing the flop, your perceived hand range, their likely preflop holdings, strength of your hand, texture of the board … oh and the position of the moon …
