My thoughts:

Let's say his 3 betting range is:

66+
QJ, KJ, KQ
ATs+, AJo+

I am ahead of 66-JJ, QJ, KJ and KQ (if they arent suited spades). I am way behind any ace and KK

50% of the time I'm already beat and have 5% chance to win (1 out).

50% of the time he has a spade, and I will lose 40% of the time.

Net: I win 2.5% + 30% = 32.5% total (2 to 1). I'm getting 17.6 to 5 on a call down (3.5 to 1).

Do I fold if a spade hits the river?
