Yeah, looks like you hit a set with TT or 55, and once the board paired you slowed down a little to try to keep the SB in. I could also see JTs.

Yep 1010. Nice work. Didn't raise the turn as you said to keep the SB in who was likely drawing dead hoping that he would hit his A or K on river. Other guy as expected had a J with QJo
