Tell me if I have this correct please. These are the spots after the blinds obviously.

9 players:

1st 3 spots=EP
Next 2=MP
co and btn=LP


8 players:

1st 2=EP
Next 2=MP
co and btn=LP

7 players: this is the one I am unsure of

would the 1st two be EP
then one spot=MP
co and btn=LP

or would it be 1 EP
2 MPs
and co and btn LP

Thanks for any help
