Any hand with a Deuce in it, especially 7/2 off suit, when I see a lowly 2 in my hand I have usually clicked on the check/fold button before the action gets to me, I would much prefer to play a 9/6 or 10/7, as those type of hands can be good if you hit the 2 cards needed to make an open ended straight Draw, and many players do not expect you to be playing such hands.
Also many players would fold pre-flop hands like that and only play them if they were suited, but even making hand's like a flush with suited cards can cause you problems, if the other player has the higher flush.
But that is what makes Poker so much fun to play, you never know when you have the best hand until the River card comes, and even then you could be beaten.
When the fun Stops, STOP!
