Pre-Flop
Something I am still curious about is in multiway pots with hands that prefer multiway situations (such as suited connectors) is it right to raise here as I did? My thinking was I can get out cheaply if I miss or I have a nice big pot to draw to if I hit.

When I was playing this hand the reason I didnt bet out on the flop was I was worried about raising, I see that this is now stupid.

To my understanding, betting the flop is correct here because I most likely have the equity edge and if I do get raised (or even 3 bet) its not terrible as I still have the correct odds to draw to my strong OESD.

Is my understanding correct?
