Your opponents will be getting higher pocket pairs more simply because there are 8 of them and one of you.
I played in a home game with my friends today, one guy got kings twice, another got fours, and another got 5's. The 5's turned into quads, one of the kigns flopped sets, the other lost a big pot (I got trip tens )
I got two pocket pairs, and they weren't till heads up. First fives, which I used to take down a small pot on the flop (no set), then I got deuces, which flopped a set, turned a ful house, and rivered into quads for the win.
So while I got two pocket pairs, I saw a total of like 10 throughout the night.
