I think he wants to know how the bidding works. If you want to stay in the bidding war then you need to bid every round, it do not matter who bids the most on the round, in the end you want to be the only one who bids on the last round. If no one else bids on the player on that round but you, then the player is yours. But if someone else bids with you on that round then the bidding goes to next round.
