Gents (and ladies),

I was playing poker earlier today online and I had top pair so I bet everybody and we showed hands. I had a pair of queens, but lost to somebody who had a 6 and a 7!

There was a 6 and a 7 on the the table after the river so they had 2 pairs... Who takes a 6 and a 7 to the flop, let alone the river!?

How do I go about legislating for that in future? I was disadvantaged after that because I had lost most of my chips.
