If a person goes after Almaty early, he might as well keep going west. All free horsemen from CSes end up at the capitol which is why Beijing was slow to fall: building 2nd army on that front.
Hmm...
I suppose there is one thing that I haven't been doing that most people do in this scenario. All of my Keshiks were either bought/built from a city or were upgraded from the four original Horseman units at the beginning of the scenario...moreover, I don't upgrade the "free" Horsemen from conquering Western Xia and I usually don't conquer Almaty, nor do I ever buy/build Horseman units from a city.
Why don't I ever convert the "free" Horseman units from Western Xia? Well, because of how I split my armies early on: the Keshiks taking Beijing need a Horseman, and the Keshiks coming from Karakorum and massing in Western Xia also need a Horseman.
Why don't I ever build/buy Horseman units? The main reason is because I don't annex that many cities beyond Karakorum, and there are many more things I'd rather have in the build queue than a Horseman unit. The 2 free Horseman units from Western Xia are more than enough.
However, it is an interesting idea to go after Almaty early to have free Horseman units to upgrade into early Keshiks....something I'll have to give some thought towards. One thing I'd do differently: I wouldn't declare war directly on Almaty. Instead, I'd declare war on who Almaty is allied with (hopefully India).
Why wouldn't I declare directly on Almaty? Well, I don't want to screw up my standing with the other City States, specifically the Abbasids. I already had to declare on Uighur by itself, and one more declaration on a City State on Deity just increases the risk that the Abbasids could declare permanent war on me, which would be disastrous.
Why would I prefer to declare war on India if it is allied with Almaty? Oh, that's simple. I just don't want the alternative of having to tangle with Persian Pikeman units from Samarkand.
I'd also wait on conquering Almaty until you've taken Beijing. Why? Because IF Almaty is allied with Persia, you want those fast Persian Pikemen invading conquered Almaty to move only two hexes a turn, not three.
All 5 starting horse, the one with names, became keshiks and went west through Persia, Arabia, Byzantium and Russia: Genghis Army. Second army (Kublai) took care of Jin, China, Japan and India.
For me, the Mongols and the original named Horseman units (minus the Merkits) are the Keshiks that are softening up Beijing. I haven't ever given this group a name, but I suppose I'll call them Strike Force AWESOME.
The group of reinforcement Keshiks coming from Karakorum and massing on the southern edge of Western Xia plus the Merkits also don't have a name, but I guess I can call them Strike Force BADASS. Since they are bought or built in Karakorum, it is typically 2-3 Keshiks in strength.
AWESOME's Keshiks will likely all have three promotions by the time Beijing falls. If Jin still holds Liaoyang, AWESOME's Keshiks proceed to soften up Liaoyang. If Liaoyang has fallen to Green China or when Liaoyang has fallen to me, AWESOME's Keshiks pounce on Kaifeng.
Meanwhile, BADASS's Keshiks will proceed to soften up Jin's western most city during the siege of Beijing. Since BADASS Keshiks don't have the promotions of AWESOME's Keshiks, BADASS's progress will be noticeably slower.
AWESOME and BADASS will eventually converge on Kaifeng. Once Jin is finished, I choose Engineering to make my progress through central China much smoother. Once they converge, AWESOME and BADASS cease to be separate entities.
The combined force will seize the two Green Chinese cities closest to Kaifeng before splitting again. This time, I actively put veteran AND inexperienced Keshiks in both forces, so that neither force is completely impotent.
One force is dedicated to wiping out Green Chinese cities that prevent Western Xia access to the Silk Road, and will later conquer Lhasa.
The other force is dedicated to wiping out Green Chinese cities on the southern and east coasts of China.
I usually finish off Lhasa and Green China at about the same time, with new Keshiks diverted to whichever force is lagging the most. The two forces mix again and split again before I start massing Keshiks through the eastern most access path to India (the one with Lhasa on its northwest border and Dali on its southeast border) and Keshiks on the Almaty/Samarkand border. War is initiated on Persia and India more or less simultaneously.
Phew, I'm tired. I think that's enough for now.
