This is the round i won
I started it with attacking up (low palace) till half round while saving my gold then switched to attacking down and high palace at mid-round. I recorded the order in which I bought techs and certain other events during that round. Since I ended up winning the round, I thought this may serve as a good guide. In retrospect, I find now I did some minor mistakes in the tech order but nonetheless, it is still pretty good. Enjoy:
