When playing a table full of fish limping and playing %70 of hands. I tend to focus on the hands that will flop me a draw of some sort, and early on while there is still 2 tables, just shoot for 3 of a kind or better and stack the weak player. Not hard when they tend to be calling machines. Sounds like seeing at least the turn card is fairly inexpensive and has great pot odds
. I would say play about %50-%60 of your hands against weak limping opponents that are calling machines, and of course crush them with your premium holdings when possible.
