For anyone else who is between 92-100% confused with all the percentages being thrown out - you are not alone. Maybe if I took a some time to really read what is all being said it might make me a beter player - but I have a simple test - if I think I still have a good chance to win - accept double. If I think I have a good chance to lose - deny the double. Depending on how many points are left - how close the match is can help determin if I want to take bigger chances or not.
Ok, just wanted to get that off my chest. Carry on with all the percentage talk... :-)
