I put slider to 0% hoping to trade later and save beakers. End turn and Liz gets Broadway (better her than the others). Izzy gets a GG for her war effort. More importantly Elizabeth drops into WFYABTA--the trading plan has a set-back.
Take a look at the techs to consider my options and what do you know...
KK has Radio already (and is in a golden age)!

We're in a race for both the Internet and the CR, but I figure KK is the main contender in terms of constructing the wonder (GA) so I decide to trade Radio to Izzy for AL. This works out very well because we can then trade her MM for combustion the following turn (gaining a lot of beakers towards computers).
-radio+gold to Izzy for AL
-micro some trades for Broadway

(change the export of Bren/Liz)
-MM+gold to Izzy for combustion next turn
-set slider to 100% and put research on industrialism
I decided to workshop Novgorod too in order to boost our Rock N Roll odds.
-trade mission to KK for 2100 gold.
We get a great event 1695 AD. The other options are ~600 gold and barracks +2 EP. Happiness is the clear winner here.
Good news: We can get the CR wonder if we really want to.
I played to 1705 AD and will turn it over here. We're faced with a choice--do we whip to guarantee that we get it, or do we risk it for more output?
For me there's not much of a choice--I want to whip it for sure (despite penalties). The overflow hammers won't be useless either seeing as we want WS ASAP too.
If we're lucky we'll get RnR too--it's currently at 4 turns.
KK cancelled ivory trade (he's got industrialism).
We should be able to get some good stuff from Izzy with Industrialism.
We have railroads now (and maybe emancipation next turn)--so the workers will be busy railroading over trees and cottaging everything.
