Simple question about a straight on a 4 flush board.

[Proofrock]

1000 FPP round 1 WPT satellite. Top 5 get seats in round 2 tournament which awards 3 seats to a WPT event. At this point there are about 18 people left.

What's my line? I'm depressed to see a 4th spade on the river, but I don't know if it's best to check/call, check/fold, small bet + fold to a raise, push and hope he doesn't have a spade? Suggestions on flop / turn? I felt awkward the whole way. No special reads on Villain, as he just moved to the table a few hands ago. Thanks.
