Flopped 2 pair (PP 11)

I tend to think the same way as you, except I believe this is definitely not a hand you should fold even early in the tournament. 2 pair is only very beatable in a multiway pot, a 2 pair in an uncoordinated board with only 1 other person is very strong. Treat it like a HU, except a more narrow hand range. I wouldn't take any chances for someone drawing out to a flush and shove all my chips in here at any stage in the tournament.
