question with pesky bettors

[Chris Daddy Cool]

simple question

you're raising preflop. but the guy to your direct right looooves to bet into you when the board is kinda scary for your hand. you dont' really know much about his actual postflop play because he hasn't had to showdown his hand.

examples, i have KQs, but he bets into me on a ragged board

i have red jackes but he bets into me on a A high monotone board

it doesn't seem to matter the pot size or the amount of players, but he does it with frequency.

also half the times i've raised. the other times i've folded. but when i've raised with overcards or middle pair or whatever, he employs the stop n go on me.

what is your general strategy against this type of player? or is this too general and you would need specific hand examples?
