Allow me to share a simple but oft made common sense mistake made when Vbetting.
Make sure to double check your bet before you press enter.
It cost me well over 1200 vcash last night on a win/win bet.
And if IB or another vbookie, or even a more experienced bettor comes into this thread.......question.....
Once you've noticed you made an incredibly stupid mistake in your bet, is there a way to change it?
