I agree with what others said about ensuring that you have the right image for it. These 100nl games play so so so nitty that I could see a lot of players folding the turn with everything worse than a pair of kings.

If you have any kind of reasonable aggressive image then you played it well. (The fact that this is SB v BB makes it a little better even if you don't have the aggressive image because it's a spot a lot of people just assume others are light.)
