At times it works getting good winning amount. Because for a player the odds will be very high and the opponent gets very low odds, only the luck is the factor which decides the winning in such matches. Mutual betting too cannot profit us depending upon strategy. Luck is much important else loss will be high than common betting.
Without luck in betting you can't do anything But it's true that in mutual betting odds for underdogs are much better than in normal betting. I look forward to Arsenal vs Watford game, odds for now on Watfrod are 16.015 on this OneHash site
