I'm thinking I missed some value by shoving, but I've become so accustomed to fast playing sets that it's difficult to turn off. Also, my standard is to buy in for 100BB's because it makes my decisions easier pre-flop/post flop. Constructive criticism is welcomed.
If you are comfortable with your game, and you can confidently say that you are better the other players at the table, there is no reason to not have the maximum buy-in in front of you at all times.
Although I would almost never recommend slow-playing sets at 2NL, this is one case where you can. The board is so dry that if you have the best hand now, you are almost always going to have the best hand on the turn. Although just calling the flop and open shoving the turn is definitely a viable option, I would have played it just like you did.
I think this belongs in the BBV thread of micro, really. The two villains played pretty well for 2nl. Villain 8 had 25BB before the hand and shoved it in with top pair, just like he should have. We don't know what villain 1 had, but after your shove he realized that his hand wasn't going to stand up to your obvious set and folded.
Playing this way with sets probably works fine at 2nl, but you'll need to slow down and recognize when you are wildly ahead on the flop if you want to win even at 10nl. In this case, there were no big raises pf, so nobody had KK most likely. There are no draws with this flop. You're out of position. Check and see if someone has anything first. There are lots of people in the hand and somebody probably has a king. Let them bet out first. If there is no betting on the flop, then you can bet the turn. As played, you merely want to call. There's virtually no chance the turn can hurt you (another K gives them trips, but you a FH. You can't worry about quads).
I don't mind your push tbh, since there'd be less than a pot sized bet left on the turn anyway and we're OOP (if we were IP we'd have a lot more value to gain by letting Villain 1 lead the turn himself). But I don't mind letting a card peel off since we're pretty much invincible here. The only thing to worry about is an Ace coming off and possibly killing our action if Villain 1 has a King (which he may well do).
