Anatomy of a monster pot

It's a 10-player 5¢/10¢ limit table at PokerStars. I'm in middle position, and am dealt 3♣ 3♥. Four players and I call, another player raises, and we get seven players to the flop:

5♥ 7♥ 3♦

The first three players check to me. I've hit my set of threes, but there's a flush draw out there, and if some crazies are at this table, an inside straight draw. It's too early to assume that I'm behind, and if I'm not behind, the proper move here is to bet. I'm in for a nickel. Two players call, and the original raiser raises again. It's unlikely to me that he raised preflop on a flush draw; I put him on a high pocket pair or two high cards, none of which matched the board. I'm still ahead. The cutoff player, the button, and the small blind fold, but the big blind calls. It's time to raise to build the pot, because even if the two players between me and the raiser fold, the three players to my right are sure to at least call. Everyone calls, including the original raiser. Nobody's got a made hand yet, I'm sure.

The turn makes the board 5♥ 7♥ 3♦ / 8♥.

A straight might have hit; a flush might have hit. I'm sure I'm behind now, but the first two players check, so I bet 10¢ to find out where I am. Two callers again, and then the original raiser raises. I'm putting him on a couple of high hearts, maybe KJ. He's hit the flush, and I'm behind. With everyone else calling, though, I do to. I need a 5, 7, 3, or 8 to hit the board to make me a full boat to win. That's 10 cards, and the pot odds are certainly better than 4.5:1 here. Heck, even a raise might have been a good choice, but I just call. Six players to the river:

The river card is a nice looking one, making the board 5♥ 7♥ 3♦ / 8♥ / 7♠

I've hit my full house. The only hands that I can reasonably expect that someone has to beat me are pocket 5's, 7's, or 8's. Any of those hands would have raised more aggressively on the flop, I think. I'm nearly certain I'm winning, and I think someone else has their flush and are incorrectly sure they're ahead.

It's checked to me, and I bet. To my surprise, a guy to my left (KarizZma2k) raises. I think he's got a seven and he doesn't think we have flushes. Good news for us. The original raiser just calls (does he know his flush is no good?), I raise, and the guy with the sevens caps it. Five of us go to the showdown.

The late raiser, shows 7♣ 6♦ for three of a kind, Sevens. Just what I expected. He was on a straight draw, and backed into trips.

The big raiser, as I almost predicted, shows Q♥ K♥ for a King high flush.

Another player mucks his T♠ 8♠ (I've no idea why he stuck around after the flop). The fourth player mucks his pocket deuces (how can he stay in with a board like that?) My full house, threes over sevens, wins. I take down a $4.72 pot, netting $3.30. In the chat box, I express my amazement.
