This is what i would suggest. This example is early, middle, and late of the first couple hours untill antes kick in.
Early Play-(First 20-30 mins)- Stick to AA,AK or KK maybe call a limp or two tryin to see a cheap flop with a small PP. i only call the limps and then fold if they dont hit. it helps keep my table image as semi-tight so that everyone doesnt think ure waiting on KK or AA lol.
Middle Play-(about 30 mins into trny untill about first 60/75 mins)-Open up the range of hands. As most uberdonks are gone at this point or u have already identified them. This range would include QQ,JJ,1010,A10 and higher suited, and still occasionally the smaller PP since these hands dont come that often to keep my image as a semi-loose player.
Late Play-(75 mins untill 90/120)By this time u should know who is playing weak tight and i would keep my hand selections about the same but be a bit more agressive at this stage. This is about the point antes kick in and u want to have a good strong table image to be stealing them. Would start maybe tossing a couple raises with good suited connectors out there to throw off opponents. Make bigger preflop raises with quality hands and maybe repop the same person playing weak tight a couple times so when u pick up a big hand they are more likely to pay u off with a marginal yet crushed hand.
