Considering the massive amount of media flooding the internet every second and how much of it is the same, your best bet is YouTube. There are hundreds of poker “training” sites, and everyone claims to be the best. Unfortunately, it comes down to how much you’re willing to pay for their services and attention to your progress. As the old saying goes, “the best advice is the one given freely.” You don’t want to invest in something without first seeing what you can achieve without it. You can find tons of good poker channels that give great advice, from basic to advanced, on YouTube. Some of them do sell online courses that provide more in-depth tactics. If you applied their free advice and saw results, it’s a good idea to enroll in their classes.
