Blinds are small to medium in size, 5 or 6 people limp and then c/o, button, SB or BB bumps it up one unit....

WHY?! what in god's name are you trying to accomplish?!
Actually I have started using this play on some loose passive tables. I've found it works nice with a table where many will limp, but most will fold to a 3BB raise. Another aspect of the table I want to see to use this is lots of folding to pot size bets on the flop. The idea is to use it on drawing hands to get the pot up so that when you hit the flop you'll keep more people in. I'll use it on Kx and Ax suited, suited connectors and suited one-gappers, and any pair. It has seemed to help some on this exact type of table. After all, if you arent getting paid off on your monsters, you gotta find a way or find a new table.

Another instance in which this is a useful play is at a table with several people who won't raise preflop with a premium hand unless someone else raises first. In this case I use the min-raise for information with good or better starting hands. If I have AQo, I want him to give away that he has AA, KK, QQ, or AK. Otherwise, it's hard to know where you are at on the flop.

Obviously these tactics only work at crappy low limit tables. But when people use stupid strategies, sometimes it takes a stupid strategy to beat it!!
