The flop is most definitely not wa/wb. Look at all those draws! I kinda don't mind a check though depending on how aggressively you expect the other players at the table to play a draw since you have to fold to a raise. I think you can bet or check on the flop sometimes.

River I think you need to lead out for value. You have the best hand a ton and I don't think anyone's going to bet bluff a missed draw into 3 players. That doesn't mean I think you're going to get called a huge amount, but I think a bet of ~$8-10 is best. Don't think we can really rep a Q though since we would def either bet or c/r flop with AQ here, so we are perhaps a little vulnerable to a bluff raise but I wouldn't expect this to be a problem vs these players.
