Yeah tech trading helps a lot. For instance trading PP saved me one GS. I spoiled relations with Gandhi and there is no way to get him to friendly again. That would not matter if I could cap him. I can keep Mansa friendly and Gandhi is trading still.
Great idea to pick a commonly hated AI, I haven't thought about it much.
T133 Frederick asked me to DoW Elizabeth and I did it. That was convenient as I was going to do it anyway. Basically its +1 diplo fo free. I take York winning all fights at ~97% odds.
T136 I got some really bad luck here. Lost 7 cuirs at 45-60% odds. Liz had 4 survivors with ~1

, chariot killed of them at 90% odds, including that pesky pikeman. Who could think that chariots can be that useful.
After that failure I moved to Hastings an captured it without losses. Just a couple of longbows on flatland 70+% odds.
BTW, my research rate imroved to 294bpt. It was just above 200 not so long ago.
T143 Communism. Received a free GSpy

That is just 1 turn later than the date projected with 250 average bpt. And it's 3 turns earlier than in the previous game with triple commerce start. A bit of improvement.
What was I doing on turn 143 in the NC193 game? (T246 launch)
I still have a GS that was meant for bulbing PP. When do I use a 2GP Golden Age? Depends on many factors. That will take a lot of planning to make everything fit.
Will I use Kremlin? I don't know. Then I need a new GP plan, because I'm going to use a 3GP GA, probably 4GP one too and use Great Scientists for bulbing. I also need to expand to at least 25 cities, preferably 30. Need to decide on slavery->caste-SP as well. And all of it is tied up with GA.
Mansa does not have stone and he's just researched Scientific Method. I think I'll take my time and get as much failgold from it as possible. Rostov and Tver still have 9 forests and I don't see any other use for those. I'm not sure how much I will use Kremlin though.
Moscow has grown to size 10 and is doing great. Soon enough it will become a powerful hammer-heavy bureau capital which it is supposed to be.
About to attack London once again. There are 19 cuirs and a trebuchet ready to strike on the next turn. There are currently 12 units... I think I'll do it this time.
Frederick's stack is 3 tiles away from London. Perhaps, I will bribe him to make peace.
A bit of statistics and tech situation. Tech rate increased to 343

per turn. Hard to project it at this stage of the game.
