So opening the top 10% hands in EP early
Note it doesn't say "open
top 10%" but just "open 10%" in early position?
If you only open the top 10% then people will quickly figure that you will never have stuff like 78s in this situation and consequently bluff you out of pots on low flops.
You can run a simulation and check which hands win most often if you just let it run to showdown...then pick the top few percent and fill up with some other combos that cover flops that don't hit those cards well.
