Hi Steve!

I don't mean the seller out bidding the high bidder on his own auction
but bidding against him on someone elses auction...

I didn't phrase it right in my first post....

Seller A has a chip up for auction...Buyer B is the high bidder. Seller A
sees another auction from Seller C and wants to bid but notices Buyer B
is the current high bidder on that auction (same high bidder on Seller A's auction)....is it unethical for
Seller A to bid against Buyer B in the third auction?

Thanks Steve! Sorry for not wording it better in the first post.
