That's the point Todd!
Do you ever not bid against friends?
Do you ever "let one go" because of who was bidding?

After the auction, names will be posted...
but I have participated in several private auctions of "better chips" and was glad to have taken "personal competition" out of it.

If the seller is reputable... there shouldn't be a problem with shilling. I just bid my "max" (usually using esnipe) and hope it is enough.
