The Winner’s Curse

with one comment

This phenomenon is known as Winner’s Curse. Let us take an example and then we will talk on it.

A teacher comes in a room with coin filled in a glass jar.The  teacher gives option to the student to guess for the total amount of money, the guy guessing largest amount of money will be getting the jar for that price. Almost more than 60% of the student will be bidding for nearest value of the sum in jar adhering to wisdom of crowd and some will bid for quite lesser than the actual sum and some will go for more than the actual sum. The guy winning the bid has paid more than the item auctioned values. The winner always gets the feeling that he overpaid.

First of all, let’s see what common value auction means. Common value auction is the type of auction where the item has got a fixed value for all participant for example a 8-GB USB drive. Its market value is fixed and costs equal for all. So, when in auction most of the people will be bidding near the market value but the guy winning the bid must be bidding higher than other fellows i.e. higher than its market price. So, after getting the product he gets a felling that he could have bought it in lesser price in market.So, it becomes a losing situation.

If the auction is not common value auction then there is different situation. Lets take example for bidding of bat-mask and bat-belt. I am a bat man fan so I could want to buy it for $150 but for one of my friend who doesn’t like batman at all it could have a value of less than $10. So , in this case, the winner is not necessarily loser. One of the way to avoid winner’s curse is to bid closets to market price.

WCC 2008,Bonn : Day2

with 3 comments

The second game of the match, every viewer was thinking a very good game to go and they got it but again the game was draw.The opening was Nimzo Indian opening but pawn structure later got symmetrical around move 12 .At move 23 Kramnik sacrifices a pawn to gain control of e5. After a long struggle at move 30 Kramnik seems to get compensation for his lost pawn. After move 31 Anand is running short on time and Kramnik has plenty of time as compared to his clock, so he may mess the game. So, Anand accepts the draw offer and again the is drawn. The score upto now is 1-1 (with 2 games 1/2-1/2) for Anand and Kramnik. The pgn for the game is given below. You can watch is using any pgn viewer.

This was the first game of very anticipated World cless Championship 2008. This match is considered to be the decsion maker since  all the FIDE championship after Kasparov’s breaking from from fide were tournament. This match also got high significance due to Kramnik’s asking about the value of the tiltle since it was gained through a tournament not match. So, the result of this championship will prove who is rightful owner of the title.

The first game started today at 3:30 CETand ended after 3hrs 4min of long stressful time.

The game  in pgn is given here:

The game started with d4 . Vladimir plays much regularly with d4. Opening was exchange slav

after 4.cxd5

and remained symmetrical for long . At move 12 … Ng4 Anand offered for exchange of knight and Kramnik accepted it .

After13… Bxg4

The game remained in balance till move 14… Rxc6 where Anand sacrifices a pawn for better development.

After 14… Rxc6

Now Anand moves his queen to c file and offers exchange of queens, Vladimir excepts it because it is better option to exchange compared to avoiding it. Avoiding the  exchange may make Kramnik’s queen vulnerable. Now Kramniks castles at move 17 0-0 to connect his rook and try to contest for an open file .Kramnik keep on trying to push e4 pawn and on 22… Rd8 Anand tries to prevent d5.

after 22… Rd8

After Anand takes 25… Rxa2 material is balanced. All the rooks are off the board after move 31.Bxc7 and we have equal materials as well as bishops of opposite color and game is moving toward a dead draw.

at the end of the game

At last the game is draw by agreement.
It is good for Anand, getting an easy draw with the black pieces in game 1, it is a psychological win for him.
Let’s see what happens in game 2 tomorrow.
