Why people bid last second?

[cracicot]

It's a good tactic to bid in last one and it's giving you an advantage, but also you are risking a lot.

Its a good tactic but can easily be worked against you. I prefer to bid first for 2 reasons:

1) It shows that I'm in the game...I want the player.
2) Bid first and the other player is forced to bid to stay in the game. The next round, he is in control and you bid at the final 2-3 seconds and win because most of the time people dont want to spend that extra token to make sure you win.

I have won MANY an auction like this.
