What if for an open auction nobody bids on the painting? Is there an minimum amount for the player who played the card (like 1000), or is it free?
I encountered this situation when a player played a painting with an open auction and it was rather obvious this painting wasn't going to earn you money.
per the rules:
"all bids must be in units of 1000"
"If no player makes a bid, then the auctioneer gets the painting for free (exception: see "Fixed Price Auctions," below).
So, if a player is going to bid, the minimum is $1000. If they are not going to bid, then the auctioneer gets the paiting for free. I guess it's assumed that in an open auction, the auctioneer starts the bidding at $0. If no one bids, the auctioneer wins the painting. In a fixed price, if no one bids then the auctioneer must pay the set price to the bank and the auctioneer gets the painting.
