I reckon you have several kinds of strategies you can use at auctions.
The example you described is a classic closure strategy.
As you near your limit, you somehow communicate this to the others and the vendor: this is typically done in 2 ways: either as you pointed out: a large bid to indicate that "this is it", or by decreasing the amount of bids: 10k, 7k, 5k, 2k, 1k shows the room left for negotiation is quickly running out.
You can also use either in response to the other: if a buyer has been decreasing its bids, you might be able to snatch it with a larger one at the end.
If a buyer has just made a large bid, you can fight back with a 1K bid: what will she do?
These are only with regards to closure, but it would be interesting to look at different behaviours to initiate and drive the auction.
It's all about communicating (or lack of) to the others.
Interesting topic!
But in the end it really comes down to determining and sticking to a predefined maximum price you can pay for the property.You can then go and drive the auction, showcasing you want the property and are ready to respond to any bids placed against you (that might make some bidders think they cannnot win it), or sit quietly and watch it unfold and strike at the right time.
