It just sucks to always have a 50% to win the pot preflop
I agree with most of you depends on the site,table etc. I like to see the flop with any pair, the lower the cost the better with small pockets.You want to see the flop for cheap and If you do not hit trips GET OUT !!
If the table is down to 4 players or less I usually push a little more with the low pockets like 2's and 3's
