Don't believe I almost missed this
The instant I decide to follow my rule again, I decide to break it. There is always an exception to every rule. 100% payout(or break-even) beats every other rule.
All-in(almost) on Federer-Jerzy match.
If Federer wins, I make a profit of 27, if Jerzy wins I make a profit of 45. Not much, but definitely better than the -10/+57 I had with my earlier situation(10 on Jerzy). And it will break my current losing streak. Although it may start a new one but that one will only have a length of one.
Actually, not sure why I am even making this post. If anything, it will make you vBookies more careful next time which means no more win-win markets. So you folks can assume that you didn't read this.
