People go to a Casino and lose 100 dollars in a millisecond and don't worry about it.
If you are worried about 100 dollars when you are interacting with a world champion then you may be a nit..........
To take the time of a top professional in just about any field for 100 dollars is not that much cash.
100 dollars ain't what it used to be.
Fedor is an outstanding young man and a champion.
Did you play them for the money even?
My experience regarding champions, is that they will load up hobbyist types of players with weight, if you bet something.
I've also said that you need more weight than you think playing top players.
