What would suggest to us retailers to play the game like the professional and the MM?
This:

There is no edge needed in trading simple calls and puts, you are just making directional bets. No need to conern yourself with market makers or professionals just like if you were buying a stock outright. There is no special math or models needed to buy calls and puts. Study the underlying, pick a direction, pick a time frame, understand the basic risk factors and go for it. You don't need a quant or Ph.d in finance to simply place a directional bet.
Just one more thing: A directional bet works well in the current bull market which is essentially straight up since 2009. I have no ability to predict when this bull will end and not sure what to do when the bear arrives.
My account took a terrible beating from Feb through May of this year, it is easy in hindsight to say change direction in a correction/bear but real life is not that simple.
