Ok here's my opinion.
In general I'd recommend a tight image and folding these hands but it's just can't be correct when we're so deep especially when vs bad players.
Say for example we have a tight UTG open and we have 78s in the BB and we're getting 2-1 this should always be a call just purely for implied odds
. The hand isn't going to get us into trouble and they are easy to play.
As for opening, it really depends on the position but I still open kind of wide early in tournaments. It isn't a leak to fold marginal hands but if you feel you're at a table with an edge and playing vs fish you want to be playing as many hands as possible especially in position.
