1st trick -> Place an outrageous bid to discover someone elses's bid. Used by people on auctions they are very interested to win. Lets say the current bid is 1000 Yens and there's someone else you believe bidding high. So you place an outrageous bid of lets say 100000 Yens that should outbid him for sure. The auction goes up to 13000 Yens and you are winning. Then you just have to lower your maximum bid to 13000 or 13500 Yens. The effect is that you have outbidded the other person with only 2 bids, what makes him believe that you are going high for this item. The double edge sword thing is that if the other guy had placed a bid of 90000 Yens you are screwed. This cannot be done on ebay because you would have to retract your bid, and that leaves track of your actions. The "offended" person could then take action against you.
Actually, not only does ebay record the retraction, it also emails the previous bidder to notify them that they have been outbid. Even if you use a different ID to place and then retract the bid, it's pretty obvious what is going on.
I have had this done to me a couple of times. In the first case, it was easy to counter-bid the expected snipe in the last second or so of the auction. In the second case, I wasn't willing to exceed my first bid. It let me redirect my money in another direction sooner, since I didn't have to wait until the end of the auction to see if I won or lost. I still made sure not to over commit in case the "tricky" bidder changed his/her mind, but I did find it very helpful.
As for using this method to phsych out the other YJ bidder, I'm not sure how well that works. I decide how much I'm willing to pay for an item. It realy makes no difference to me how the other bidders behave. I couldn't care less if someone bids in multiple small increments or it's all in one large bid or even odd amounts of yen. My own bid patterns vary based on my irregular work schedule more than due to any "trick" or strategy. Sometimes I bid my max right off the bat, sometimes I don't.
As for accidently typing in the wrong number of yen, I have to admit I have come close to doing it a couple of times, but have always managed to catch it.
