Avoid playing Q7 it never goes well buddy if you aren't outkicked you are outranked by the higher flush draw. In cash games play strong hands and maybe on occasion speculative hands like 89suited 910 hands that can improve dependent on the flop texture you get. Try to only play in position raise often for valuable information of opponent strength. Sometimes I'll raise utter junk and hit but I wouldn't do this if I wasn't way up on my starting stack. Play tight make pots huge when you have it and know you have them that's the best advice I could give. Oh and if you can play at pokerstars always muck k9 of diamonds it almost always gets beaten by Ace of diamonds flush even grosser than your cooler.
