Don't let the camera be on top of the card. Try a 45 angle so the flash do not hurt the card in reflection. I do that with my lates cards before and work good.
He bid you, because he enter a bigger amount of ponts in one time. Who ever bid more on credits, always will be on top. Until you surpass his amount of credits points (you need to discover that by bidding until you reach his credits and pass it), he will bit you everytime you bid. To bit him, bid 100 points or more, until you see that you afre the winning bidder. Hope this help :-o)
