I said that a little wrong. I didnt mean 77 was unplayable I just mean you should be less willing to raise speculative hands and more willing to raise weaker big hands.

e.g. in a tight game you raise 55 because

a) People wont stack off in an unraised pot without a monster.
b) you stand a reasonable chance of taking the blinds/ flop pot with a cbet anyway.


In a loose game where people are calling down with weak hands you cant steal and people will stack off (or come close) in unraised pots with top pair. This means you raise (to isolate) with more hands that can make TPGK but you are more likely to limp speculative hands and only bet them once they hit.
