Weak top pairs from the blinds

[ajmargarine]

I'm having trouble playing these kinds of hands. Could use some input as to a general strategy to use in these situations. I don't have one. I check/fold, check/call, lead weak, lead strong. And I usually find the wrong thing to do at the wrong time in these hands.

These are hypothetical hands. To take out variables, let's say it's your first or second hand at the table, no reads on anyone, and everyone has mega-deep stacks.

Full table. .50/$1 blinds, NLHE. In every hand there's 3 players who limp in from MP/LP, and then both blinds play, so it's 5 handed making a $5 total pot preflop.
