I appreciate the offer - I'm downloading that app now - i think I'm going to set some short term goals first and see if I can spend a month getting good enough to consistently beat the low level AIs - right now I still lose to really low level mistakes that I think repeat play with AIs will iron out.
Once I won't utterly embarass myself - and here I'm taking a conservative definition of the "utterly" - then I will definitely take you up on this!
