Re-raising??

[ZenMusician]

Not to mention when you have a premium starting hand
preflop. You should be at the very least reraising AA, KK, QQ,
AKs and very often JJ, sometimes TT-99 in later position.

Poker books are expensive and there are a ton of them.
Getting Started in Hold 'Em by Ed Miller (look on this site)
is a fantastic way to start - it will teach you how to raise
and re-reraise (which is a raise of any raise, not just yours).

There are more advance situations for which to reraise, etc., but
for now, learn to recognize when your hand will be best a good
portion of the time and get your chips into the pot.

Good Luck and welcome to 2+2
