Here is a player type I have had trouble with in the past. They will be sitting to my left and calling all my late opens, even from the SB. They will then check/float to the river to win pots with 2nd pair, third pair. I have not run into this type in a while, maybe this was because of the loose ranges I was playing then. The situation will be a soft table when you can win pots easy in position by C-beting flops.
