$1000 eff. 50ish gentleman opens MP1 to $20. He's played pretty snug so far, probably his first open in the last 20 mins although he has limped before once or twice. I'm in BB with Q♠ T♠ and call.

Flop: 9♠ 4♠ 8♥ $42 I check, he bets $20, I checkraise to $80, he calls

Turn: 2♠ $202 I bet $150, he calls

River A♠ $502

I have played with him before and despite being generally tight he has an aggro streak in him and can rep a spade if he doesn't have it.

What should we do now and were previous streets OK?
