Gheez - You didn't miss it, I PMed my score/times to Metro. I messed up some of my calculations anyway... darnit >< Metro and I have been going back and forth because I seem to have added an extra week and extra day to my town and vacation scores. Not that I ranked in the top 10 or anything, but I want to have my proper credit!
As far as strategy... Did ANYONE ELSE have issues with certain sims not wanting to stay seated at the chess table? I was in River View and Jamie Jolina would NOT sit at a table! It took me almost a week to complete any games with her. ARGH!
I wondered, afterwards, if that is what had happened. I'm glad it's all sorted out for you now.
I had problems playing chess too. Sometimes it two or three attempts to get them to actually play. Then, if I was really unlucky they'd leave and when I called them back I'd have to wait because they were at work. I'm reading the other thread for hints and tips on what I should have been doing.

Still, although I took a long time, I did enjoy Metro's challenge.
