specifically as the aggressor:
any suited ace
any 2 wheel cards with some suits
any 4 low cards
high hands, even bad ones
premium hands obv
even middle cards because there are no multiway pots and you need nothing near nuts to scoop
honestly you're better off asking what's the few hands you should not play
you should play very loose and aggressive and very sensitive to position
when you are the caller, you should play tighter than above (never calling with bad high hands or middle cards), and not give away any info about what hand you have pre.
