Biggest Pot Ever!

After weeks / months of being on the wrong end of these big pots, I finally get my hand to hold up! This is clearly a milestone event; no suckouts, no split pots, no nothing! I -clear and simple- win the biggest pot of my career.

We're playing [essentially] 200BBs deep, so I make the call which over time will make profit. I have implied odds of ~75x in making this call.

Could this flop have been *ANY* better? I'm not sure what to do here, so I ~min raise - which I wasn't so sure about at the time.

Here's my take: It turns out that it was probably the best move I could have made. To my opponent, it showed that I perhaps hit a set or a weak King. Perhaps AK. I'm guessing that I led him to believe that I did not have strong diamond re-draw.

Turn: ($27.25) Jd (2 players)
UTG+2 checks, Hero bets $13, UTG+2 raises to $92.45 all in, Hero calls $79.45
I was very disappointed to see this diamond hit the turn. I figured it would kill my action. BOY was I WRONG! From $13 to all in? Without the nuts? What does he possibly hope to accomplish here?

He sets the turn up such that only a better hand can possibly call him - with... perhaps... a pesky flopped / turned set as a distant calling possibility. I'm not getting this $13 -> shove, but thanks!!!

River: ($212.15) 9s (2 players - 1 is all in)
