Have you watched Cog's Heads Up Fundamentals: Playing Tight Players yet?That is basically the same thing as 25% of the course.The other 3 videos of the course will likely be made in the future, we just want to make sure that his long list of 100+ students doesn't get offended that they paid $200 for the course and then it was released and available for $25 on video shortly after.These concerns should greatly diminish in the near future, as paying a higher price for information available at one time is much different than paying even a small fraction 6 months to 2 years later.  Regardless, the videos should be a great addition to our library, particularly for starting players.

I watched some Cog's video and the guy is definitely a great teacher, but i think thoses video are 100% oriented regular speed expet the last, and so then the concepts explained might be adjusted in turbo games, well for me who need good fundamentals, i prefer avoid em for now, is that right?

I would focus more on the opponents that you see in the videos and what adjustments a coach makes, rather than trying to emulate what they are doing in one video into your "default game."If you're playing an aggressive player but haven't watched a video against an aggressive opponent, emulating some adjustments or play against tight players is going to be tough.You don't need to try to play like Cog or Primo or anybody else to learn from them.  Just watch how they adjust to certain players and in certain situations and when you come across those situations or situations similar, you might be able to draw the parallels and make the proper adjustments.If you're feeling lost limping, raising your button shouldn't be the answer.  It doesn't usually work like that.  Adjusting to your opponent is typically easier in limped pots, as the main disadvantage of limping your button is that it's tougher to build larger pots for value (or even to steal later on in the hand) and you have a positional advantage that generally justifies building a large pot (at least more so than OOP, by that I mean with a wider range of hands, you can just get a lot more value and play a bit more risky, per se, when playing in position due to the advantage of acting last and probably even being able to hit more boards).So if you see Cog check back 2nd pair on a flop, don't just emulate it.  Ask yourself why he did it if it's not clear.  Ask what type of opponent he was playing and why is he making that play against him.  If you're still unsure, just ask in the comments section of his video and PM him alerting him to your public question (keep the questions public so that everybody can learn from a coach's response).It also may not hurt to mix up the variety of instructors that you watch.  Unless you're really connecting with a coach's videos, try watching a few other instructor's videos and see if you really just tune into one of them for whatever reason.  Most instructor's videos made at the low to mid stakes in the standard membership should contain learnable material even for a rather new player.  Skates videos may be an exception, due to some of the advanced concepts he tends to talk about in both the low and higher videos.  Most other instructors tend to keep it simpler in the lower stakes videos, I wouldn't call either approach better, just different.And finally, it's just 5 games!  Comfort is important, but don't break down your success and results too short term or you'll go crazy. 

"I watched some Cog's video and the guy is definitely a great teacher, but i think thoses video are 100% oriented regular speed expet the last, and so then the concepts explained might be adjusted in turbo games, well for me who need good fundamentals, i prefer avoid em for now, is that right?"Take a look at Cog's super turbo videos if you want to see some adjustments that he makes versus the regular speed format.Generally newer players tend to have more initial success in the regular speeds though, as it allows more time for adjusting and opponent mistakes, and less pressure/short stack situations, which are usually tougher to learn because of the extreme depenency on your opponent and the harder adjustments required to fully exploit a player.

Just reading the first few paragraphs of your last large post, raising your button may be giving you more comfort just because you can identify player's ranges in a bit of a more narrowed way.For example, you automatically know a guy calling a 3x raise with 50% of hands is just about sure to fold a hand such as 73o or 63o, 53o and a host of other hands.  From that you can figure out that they are less likely to hit a KJ3 flop than a KJ6 flop (assuming more 6x hands than 3x hands are in their range of course, a usually accurate assumption here).However, that doesn't mean that you're playing any better by raising vs limping (and FWIW I'm not advocating limping your buttons or anything, just talking about limping vs raising and maybe why you feel raising is best for you now or it's more comfortable, etc.  I personally end up finding reasons to raise most buttons vs almost every opponent, particularly deep, though some if it has to do with patience, focus and structures).However, if you're limping and your opponent checks back 90%, you can't make the same sort of assumption or even the opposite as above (KJ6 and KJ3 are likely hit the same % vs a guy checking back 90% of hands, perhaps slightly less if he has 66 and not 33 in his range or A6s and not any A3 hands, but again, very very close).  But you may actually have a much larger edge against this player if he is very bad at playing low pairs and weak kickers, as well as weak draws (particularly say weak gutshots, 43 on a 26J board for instance) postflop.  If he plays too large of pots and takes too poor of lines with those hands, it's probably better to limp, as in this example if you had raised your opponent will fold those weaker hands preflop and correctly so, since he plays them so poorly.So in my example, you may feel more comfortable in the raised pot just on the sole fact that you can narrow their hand range down a bit, when in reality you're more profitable to limp.That's just an example though, don't take that literally and just limp vs guys that call 50% of raises by default, that's not necessarily correct by any stretch.I talk about this topic in this thread as well. 

Even a learning experience can be confused here, as developing concepts that maximally beat players with wide and worse ranges is certainly very valuable, probably factually is a better use of time as far as growth and learning is concerned, especially at the low to mid level and as high as into the triple digit buyins.Reading the rest of your long post from earlier, I wouldn't say Cog's videos are necessarily advanced as a whole.  I think it's very person dependent, as in one player may find xSCWx's videos to be hard to grasp and another may find Cog's or Fydor's or Primo's.  Obviously certain instructors on average will get through to newer players more often, but everybody has their own strengths and weaknesses both in identifying how to adjust, executing an adjustment and articulating that to a viewer.  So it makes sense to me that we'll see some variation from various people.I think you answered your own question on what to do.  Revisit the Cog videos periodically and work with the ones that are helping you most right now.  But revisiting is a great idea, even if you end up loving somebody else's videos far above anything else, the fact that you're not grasping Cog's videos is likely to mean that there is some value in understanding them better sometime in the future.  It just may not be right now.I'd also recommend posting some hands and getting involved in reading and posting in hand threads here, even if you're asking a poster to clarify their thoughts or reading other people's advice and thinking about it, this should be a great benefit to you.  And ask questions in the comments section of the videos, as I mentioned before.
