I was doing some study with vision as MP vs UTG raise. The had given was AKK3. What I found interesting was that vision calls the stronger double suited hands but raises weaker ss or sss hands then calls rainbow hands.

Is this because we are hoping to gain more equity with the ss or sss by gaining fold equity by raising and/or are we hoping to gain more value by keeping more of our opponents hands in play with the stronger hands. I believe vision is based on 500zoom so not totally applicable to micro stakes but I am interested in the thought process.
