Hey there!
Im mainly a MTT and SNG player and am really enjoying the videos from DeucesCracked. These videos already helped me a lot and I only watched a fraction of them.
You can try out DeucesCracked for free, because it has a 7-Day Trial.
If you decide to check it out, I really recommend the "Last Man Standing" Series by AMT and the HitchHikers Guide to Sngs by AMT and Bones I think.
If you are looking for MTT Videos, make sure to watch the "MTT Principles" series.
Have fun watching and learning
