Hey Bosco

This question is not easy to tackle because it's a very general request. Did I understand it correctly that you're interested in finding content teaching you how to play more aggressive yourself?

Basically, playing poker with a professional mindset bases on the fundamental to maximize your EV in different spots and on different tables by adjusting to the unique surrounding you find yourself in. While it is true that a LAG playing style generally reflects the strategy of good and winning players, there's also situations where being a bit more TAG might profit you more. This is why our pros usually won't lable one of their videos as "learning how to play LAG" but are always thoughtful to adjust to the different surroundings and a LAG/TAG approach is usually the result.

But of course there are specific situations where you can exploitatively put your opponents in uncomfortable spots playing more aggressive than usual if you expect them to not stand up to your aggression correctly.

My advice to implement more aggressive knowledge from videos would be learning about some aggressive opportunities that come up during your play. From there executing these aggressive opportunities with balance in mind will automatically make you a more aggressive but still solid and balanced player.

In the Learning Paths NLHE you can find some especially suited topics to learn how to choose the spots when to show aggression without blowing away unnecessary money
1) 3-Betting
2) 4-Betting
3) Continuation Bets
4) Check-Raising
5) Bluffing

Here's also one specific videos covering aggressive plays that jumped to my mind but note that there will be many more on the site:

Raising Turn C-bets - Julian Kopanskiy

Besides from that just watching some Essential coaches' live play videos will give you a good feel to explore some aggressive options because our pros frequently act quite aggressively at the tables when it's the winning play. I've set up a filter for you here:

But once again, be careful with just deciding that you want to be a very LAG player because while there are situations where playing LAG is appropriate it doesn't guarantee you to be a winning player if done blindly.

Thanks a lot fot your very complete answer.
I'm playing online for 15 years now and really know what were are talking about I just want to see perhaps new stratégies in very LAG style. But your answer is perfect, it's exactly what I was looking for, very good job, tx a lot! ��
