Lower ranks and players without amazing aim should avoid using too many headholes. An easy way for lower ranks or players without Diamond level aim to throw matches is giving the higher skilled opponents more lines of sight and opportunities to kill or gain map control. This is really only good advice for higher ranked players and not the Copper-Gold level players.
Because of videos like this every beginner thinks that you should make a rotation to the garage in the party room defense and they won't accept any other way when in fact that's not such a good idea. You don't need to be in the garage to be able to defend it, reinforcing the right side of the wall and making a killhole on the left has worked much better. You can still defend the garage but from a safer location without being open to many directions. And if there's one reinforcement left you can close the wall if needed which forces the opponents to attack through the door unless they breach it. That way you have only one small entry point to cover. Of course this might be a great tactic for pro players but in regular ranked it very rarely works. And to be clear, i'm not a pro. I'm just a player with 8 years of experience in this game.
I have a question. I play rainbow six since ying (saison two?) and a couple of months ago I started playing again and I don’t make it to get out of silver again. There lots of bad player who are not possible to predict and sometime 1-2 really good players stuck in the same way as I do. What should I do?
