By "we'll be able to finish Genghis off before T100" I mean that we could capture the two western cities in this screenshot at approximately that date, make peace, and take HBR. It is probably best not to go straight to Machinery, because Elephants will do the job of Xbows and other techs are more pressing (Aesthetics line, IMO). I built too few Melee units prior to Construction in my test, and 100+ were just going to waste in pre-built Settlers and Workers. But this was a run to get a feel for macro rather than micro.
Construction, unlike HBR, is not ideal trade bait, since we cannot do a 2 for 1 deal with Mathematics. Conversely, it is very likely that GK will research HBR, so HBR is not an ideal tech for us to research ourselves (we can get it for free).
Regarding GK declaring war:
Construction will be researched ~T76.
I tried to test the HBR beeline twice, but neither of my attempts were very good. Since I didn't want to misrepresent the strategy, and I didn't want to reduplicate the efforts of others without cause, I thought it would be better for one of those advocating the strategy to play it out.

Regarding GK declaring war:
Spoiler :
The size of the player's army will not influence Genghis' decision to go to war, unless our power rises to ~150% of his (thereby preventing it). There is a 2% or 2.5% chance on any given turn that he will try to go enter a total war or limited war respectively. The former would give us 10+ turns in which to prepare, the latter 6+ (PREPARING_TOTAL_WAR ---> TOTAL_WAR, etc.). Other checks also limit this, chiefly financial difficulty.
Once GK begins to plot, his declaration is contingent upon his having a sufficient number of units with AI ATTACK, ATTACK_CITY, and PILLAGE scripts in relation to the number and size of his cities. Again, this has no link to the player's defenses. We could have zero defenders and he could still wimp out (except that GK builds a ton of attack and pillage units, so that won't happen).
A dagger war is the most worrisome and likely, due to the lack of prep time for us. This is based upon three variables:
MWR = MaxWarRand,
NF(NonsenseFactor) = (iNonsense % 11)/10
FM = AI_FLAVOR_MILITARY
"iNonsense" is the sum of a capital's X and Y coordinates.
iDagger = 120 * 100/(MWR+50) * ((iNonsense % 11)/10) + 5 * Min(8, FM)
A total of '100' is needed to pass the AI_Dagger_Threshold. Thus, if GK's capital coordinates are 31,34, the iDagger chances will be 160 = dagger. If GK's capital is at 33,35, the chances will be 64 = no dagger.
The iDagger is further modified for military Unique Units. Again, for Genghis:
Capital can build UU +40
Agg AI is off +15
So if Karakorum is located at 33,35, GK will eschew the Dagger Strategy (+64) until his UU is available (+119). This is why he repeatedly declares war on Mansa or us in the test games: he can build Keshiks.
I may have misrepresented something here, and I screen out factors like the choice of target, financial difficulties, or other possible strategies. We also have 109 turns of enforced peace. Information is adopted from DanF's explanation.
