i think you're ahead of his raising range. i don't think you're ahead of his 4bet range enough to call.

don't confuse this three straight board with a board like 789 or kqj. villain is much less likely to call a raise and raise with 2nd pair/third + straight draw on a 234 board.

i think a bet/call raise is fine. the board is likely to significantly change and he'll probably check the turn, keeping the pot small for you.

oh last thing -- i think on each action, you're only thinking of the next action. if you step back and look at that board before all this goes down and think of what hands he's going to get all his money in with, i think this becomes a pretty clear fold.
