Sort of Theory Post

5/10 NL 10 handed

1 limper (1kish stack), I raise to 40 with A10 off, he calls. 2 to the flop.

Pot: 95ish
Flop: A83 rainbow

He bets 100, I make it 300

I played this hand at 5/10 NL and my friend asked me why I raised the flop here and his follow up was shouldn't I raise the flop with any 2? Do most people raise this flop with any 2 cards? What range of hands would most people raise this flop? Would anyone fold/call this flop?

The real theory question I'm considering right now is if stacks are deep enough and you're the preflop raiser and are bet into, should you raise barring a read?
