This is a good guide. I will link my friend to it. He keeps trying to slingshot CS against me (ya, we're playing bts, and this is indeed a sick thing to do), and then I attack with swordsmen and destroy him. I miss one valuable thing in this guide though, which is FFA diplomacy. If you see a weak civ, who's never gonna win the game (like england in the example you mentioned), and he's getting attacked (and probably crushed) by one of the score leaders, you probably wanna go and assist the guy. If all players participating understand the concept of the balance of power, then the game should be more fun. Sometimes it means signing open borders with a strong civ so he'll attack your neighbour instead of you, often it means assisting the weaker party in a war. If another player is running away with the game, you don't wanna sit around and do nothing while he is out gaining more land and more hammers. Also important. If people have no clue about how to play multiplayer, you probably wanna defend with mobile units, so you can abuse the roads in your own country when he attacks you. I've noticed that stacks of rifleman are really chanceless against cavalry with 6 movement. They simply cannot attack anything but a city, and they're probably dead before they reach the first city anyway. Sac 2-3 cats/cannons and a stack of cavalry can easily take out a stack of rifleman. If attacker comes with cavalry, and you have rifles, it's 2 movement vs 3 movement, and you want have much of an advantage being the defender then.
