Not only should it slow them down like you thought, but you also have more people to trade with.
If you want to secure a victory, then it is ok to try to slow them down. But if you are trying to win the Gauntlet, you should do the opposite, help the AI.
My second attempt has gone much better. I wanted to try high seas. I am sorry I did, with such a good start. I had 3 Gems in the fat cross. I was so far ahead of the AI that I had to wait for them to be able to trade. Some data:
Victoria. Alphabet 1990BC. Academy 1150BC. CS 880BC. Education 445BC. Liberalism+Astronomy in 235BC. Oxford 55BC. 90bpt 1000BC. 400bpt 1AD. 700bpt at the end.
When I had Education they had just researched MC. What a waste! I was so long not running an engineer that when I was able to hire him, Oxford was already available. I even had to delay Globe Theater in order to maximize GE chances.
Two turns before Liberalism I traded my monopoly on Paper for Compass and the next turn traded my monopoly on Education for Optics. Had they had those techs some turns earlier, I could have researched Astronomy myself, using Liberalism for a more expensive free tech.
After Liberalism, nobody new what Printing Press was, so I had to research it myself, instead of trading for it.
All this reasons justify my idea of helping the AI to research faster. I recommend low waters, minimum number of AIs, good researchers like Hatty, Gandhi or Musa.
Thank you, WastinTime, for the description of your OCC strategy. I have learned a lot. I previously thought this way:
I have the secretary, lets call a victory election. I hope someone votes for me
Now, I finished the game this way:
(twenty turns before) I prefer Washington to be my rival, Ill stop trading resources with Fred and Ill gift them all to Washington so that his population grows
I have the secretary, if I call a victory election Fred will vote for Washington and I will be 9 votes short. Becoming Buddhist wont help, since a tie in relations would lead to an abstention. Ill pass Free Religion and I will win the next election, in 4 turns.
What a difference!
Following WastinTime advice, I wont tell my victory date. Anyway, it is not really competitive. The affair between Fred and Wash cost me 4 turns. Slow AI research cost me 12 turns. Trading for both Engineering and GunPowder cost me 4 turns, since the free GS became almost useless. Playing in weekdays (multiple short sessions, lack of consistency, stupid mistakes due to tiredness) instead of weekends cost me 6 turns (I resisted Monday and Tuesday, but my hands trembled so bad on Wednesday that I simply had to play).
I guess the winner will have a sub 1000AD date. I will tell no names, but both Russian citizens and wild black beasts have good chances.
