I have to admit, these are some of my favorite poker sites online. Unlike much of the "fluff" out there about poker, these sites deliver the goods. Consider the sites on this page recommended.
Professional Poker Online - A player's guide to poker online - News, Strategies & Card room reviews.
Play Winning Poker - Steve Badger's poker place on the web.
Texas Holdem Strategy - Texas Hold'em Poker Strategy at MasteringHoldem.com.
Online Poker Strategy - Poker Strategy articles, forums, and online poker room reviews.
Poker Mentor - not your run-of-the-mill website. In the author's words the site lets you " Learn texas holdem poker strategy in addition to using
data mined notes on 100,000+ poker players, a fish list, indepth articles,
hand history analysis, and near-flawless preflop sheet."
Learn Texas Holdem - has a series of articles based on, you guessed it, holdem. There are various topics covered, like semi-bluffs and hand groupings, bad beat stories, etc.
Low Limit Hold'em - is an excellent resource. Their holdem strategies go deeper than the ones offered here, so if you're already comfortable at the tables and are ready to bring your low limit game up a notch, they are a recommended read.
PokerSyte.com - is a strategy site run by Bullet Bob Maxwell. He's a straight shooter, and offers advice on more than just texas holdem, which is a plus in this holdem-crazed world of today. (Coming from me that's funny as I can't play a thing other than holdem). He also has a "best of the net" listing where you can find links to some of the better poker strategy articles online. Overall, a site worthy of a visit.
FirBolg - an interesting collection of online poker advice that stretches beyond the limits of holdem, although there is quality no limit holdem advice to be found. The book reviews section is large, and helpful.
Online Poker Room Reviews - "Exclusive online poker strategy articles, tips, bonus codes, and poker room reviews to help you beat online poker. We help good players avoid bad beats". At least those are the words the author uses to describe his site. Truth is it is a site worth visiting. My favorite of the quick tips, "RELAX! I get my Aces cracked by 6-3 offsuit, too. It sucks, but it happens - especially online where people play hands like that more often. Be nice to the fish as they're the ones who will usually pad your wallet."
