Hi, I started to play 500Nl ,1kNl 8max on a site where each players post a big blind ante.
If we are 8 at the table, the pot is ~ 9bb.

Taking into account that we always play deep, (Mostly 200bb+) , and most players are rec who are playing tight :

How should adapt my strategy PF ? (Obv I have to open more)
Which sizes makes more sense ? I thought limping a lot UTG and raise around 5x or 10x on BTN is a good strat depending on how tight they are, but I’m not sure about that .
Or even if people are really tight, playing only push or fold is okay ?

My last questions :
Do you know where I can find/buy this type of ranges ?
I don’t know if it’s allowed, but playing 30-40Deep seems a good strategy also. Also not sure about that.

Thanks.
