Thank you for posting.
Villain skill level and aggression tendencies play a large factor in our UTG ranges at this stage.
Stack sizes also play a large part as when we raise this can so easily go multiway with us not being able to realize our full equity as we will seldom have position on everyone. Also other stacks can shove over our raise and we have to preplan who do we call when they shove and who do we fold to. You want to have that strat in mind before you open 77.
As we have 8 players left to act the only way to realize full equity is to shove preflop but we are shoving a mid pair into 8 players so we will most often be called in a flip situation or worse. If we have a table skill advantage we want to avoid flip spots with a mid-stack.
So a rule of thumb is: when we are a mid-stack that is when we have to play with the most caution. If our options are shove or fold then our position forces us to lean to fold unless our V are overly tight which vs the whole table is very unlikely.
Hope this helps
