It's the quick copper eventuality (along with worker stealing) that has me thinking of an early axe (now that SCT has pointed out the probable failure of an early axe rush).
Ok now I have some time to think some more. I think Shannon's numbers are spot on. Normal speed is hard to recover from doing a rush such as we are thinking.
That being said, we can get 2 axes over there by upgrading (80 gold) in the same amount of time if we build another warrior after workboat and before settler/worker (OR if we keep the one we are building just inside our cultural borders). That would make it two axes and a warrior vs. 2 probable archers. Still not good odds. We could also upgrade to 3! axes (my estimate is ~35-40% chance to take the city) or send 4 (conservative estimate is ~70% odds to take the city). Who likes to gamble? 3 axes can sometimes take a city spread out over two turns if the suicide axes do enough damage.
How do you get the archer to leave? In BTS, they wont attack a scout usually. So that tactic is out. What they will do is escort a settler and leave that lone archer defending capital on just the right turn where they cannot retreat back to the city (unroaded tile) and cant found their second city. There is no calculus in the world that will tell you when this will be without having a better look at Shaka's BFC. If memory serves he is EXP as well, so he should have a worker running around soon.
If he started coastal, I have seen some AIs grow to size 5 before building workers and settlers, but normally this is the more peaceful AIs. Sometimes they will build worker first, and sometimes on deity they will build settler first (though that is less relevant here, since he doesnt start with several units and workers and another settler which leads me to believe they are less likely on monarch to try this tactic). If attacked via worker steal, he is more likely to build more units, but he doesnt forget about building another worker down the road when he feels safe and he will not be as ******** as say Warlords AI.
Also if he is coastal, the new city would be less maintenance unfriendly with the Lighthouse.
As with any "rush", a cost benefit analysis has to be made. Certainly removal of Shaka is necessary. If we believe we can make 4 axes (140 hammers), and in so doing acquire 160 hammers worth of property (settler+worker), it certainly makes sense to do so unless our tech rate is greatly compromised. So I am still against it but that is my analysis.
