In my opinion there is a huge difference in how you might perceive your hand strength (trips) on a flop depending on the quality of cards that appear:
If you draw your trips with a pre-flop hand of KA and a flop of KK10 or something of that magnitude, you should be more wary of a full house possibility than if you had say a pre-flop hand of KK and a flop of K107. In the first hand there is that chance of the opponent having a full house, and while he either needs K10, 1010 to have that hand, he is more likely to have a full house on a high card flop rather than a flop say of K53, as In the second hand you are obviously ahead and should assume so. If he's calling you all in on a hand like that he's either bluffing
hard (dangerous board to do that on) or has a made hand. I would have played it the same as you though, you had the odds
, and unless you had a great read on your opponent, you should just play it all-in on equity.
