Sorry, I cannot agree. No limit is a game about CALCULATED agressiveness, not about random betting. A new player just does not know how to read betting patterns enough to go exploring with 5/6 offsuit. You're going to lose a LOT of dead money that way.
this is right. if you want to learn poker, get an online account (i like pokerstars), and put 30 bucks in it or something. there is no point in playing online poker for free. players don't play like they do when money is on the line, and the experience is generally worthless unless you are in it for the sheer mechanics.
then i suggest you play sit and go tournaments, where you pool an entry fee (such as 1.20 or 3.40 or whatever) against 6+ opponents, with the winner and second (and potentially third) place "moneying". These tournaments last a good while, you get your entertainment for your buck, and with smart play, you can make alot of money. Listen to truth. Don't play random betting to confuse people. At a larger table, like hold 'em generally is, your hand is up against 5 or more others. Overhwhelmingly the odds are someone has a strong hand, so your bluffs are going to bite you in the ass unless you have a very developed set of reading players.
Stick with J10+, suited connectors. Raise/reraise on high pairs or AK or something strong.
Once you get the feel of the game, you can try applying some more intermediate stuff... like pot odds, playing position well, etc.
Oh, and once you get down to 3 at a table or heads up, you are gunna want to pay more aggresively. Raise on the button if you have any high card. Fold if they reraise and you don't have the cards. Most likely you'll win your fair share of blinds. When the table number starts dwindling, keep in mind that poker awards aggresive play.
Last bit - you are gunna lose. More frustratingly, you are gunna lose to complete luck draws. This can hurt. But don't let it get to you. Its a game of odds. It'll come back to you if you stick with it.
edit: for what its worth, i'm pretty new to poker - been playing maybe 4 months now. i learned alot. i lost alot. i won it all back. and more. I'm up about 150 from my initial deposit, so even for beginners, you can turn it around if you stick with it and try to figure out the game. People who play online are pretty terrible, on average. There are plenty of fish waiting to be caught.
