The villian doesn't know whether or not you will invest more chips. Raising to 200 on the turn gives him 3.75 to 1 odds. If spade comes on river and he bets 75 into a pot of 570, are you going to fold? If he has Ax, Kx, or Qx of spades he doesn't need his odds to be implied.

I think it is obvious we play this hand differently. I would either fold or raise to 150 on the flop, depending on the player. There are three outcomes from the different ways I would play it. I could end up with 855, 740, or 590 chips. Losing 150 hurts the remainder of my tournament strategy more than gaining 115 chips helps, so I might opt for the no risk choice of 740 vs LAG or maniac opponents.
