Yes, we don't have a reasonable chance to get another turn off the finishing date and therefore lets spend money for our score, i.e. happiness.
Pre-turn: move garrison into LM to deter any AI ideas on attacking the undefended city; order some destroyers and tanks, since we have money to burn; start calling some troops back from former Viking lands for upgrading; set 20% lux
1655: pollution hits us
1660: more pollution clearing; renew deals:
Greece gives incense, dyes, gems, 175g, 22gpt, wm for spices and wool; then we donate them ivory
India gives 191g, 40gpt, wm for spices, wool, ivory
1675: Greece and India know flight; India sells us flight, wm for coal
Keltoi give silks, wm, 4g for electricity; donate them , ROP; donate them wool
sell flight to Babylon for 48gpt, 54g, wm
because of the very very small -- but existing -- chance that greece and Persia will not get rocketry, I decide to bring them in the Modern Age:
Persia gives 24gpt, 252g, wm for flight
Greece gives 132gpt, 120g, wm for mt; we donate radio and they learn rocketry

we donate radio and mt to Persia, and they learn rocketry

there goes all hope to accelerate our 20k date; start research on computer
grateful people add another peace to our Palace
1700: our furs and horse (which we don't need) deals end; renew furs for 12gpt
pesky Persians know amphibious war; strengthen LM defense
post-turn: Leptis Magna is on fighters; useful as sentry in case Xerxes misbehaves; Utica is on destroyers, Theveste and Carthage IMHO should build bombers, because lethal air bombardment is on in this game
20k date still 1745AD, Firaxis 806, Jason 1067
