Should the flop be raised to obtain more $$ from a possible straight draw or :Ks: ? Monotone flops confuse me

Raise preflop, then if you get reraised you should fold.

I raise the flop, just because if another spade comes on the turn the opponent might not want to put any more money in the pot if he doesn't have a spade. So get as much in on the flop as you can.

As played, at 25NL this is AI every time.
