About me: Ok I became a major by like my 200th game and I've been playing CC on and off for about 4 years, and thus here are some of my thoughts and musings. I'm hoping to have actual statistics to back them up soon but first I'll see the success of my musings.
Attacking: Basically pretty much NEVER click auto atk unless you are fighting with a couple hundred+ troops or your okay with losing all your men, more often than not CC likes to stack 2 troop losses thus if your attacking a place with 10 troops and theres 2 defending, you can easily get 3-2 losses in a row. However in the same respect if you atk and you get a 2 win, immediately atk again cause your likely to get another 2 win, or a 1-1 draw. I find that I keep atking until I get a 2 loss, then I go somewhere and do something for a few mins, then come back. Do not atk after youve had a 2 loss or you'll get slaughtered by the dice. I don't have an exact time to wait for the next atk, but I suggest somewhere above 20 seconds. I also suggest taking places that are defended by only 1 man, why? Because when you atk those places its 3 dice to 1, your much more likely to win and whats even better, you don't lose anyone when you take the place, your man stays guarding the place and 3 of those places=1 more troop a turn


Defending: Honestly having 1 man on every place is a recipe for disaster. I suggest 2-3 on vulnerable 1 man places you don't want your opponent to take easily, most players hate taking places that defend with 2 dice but are defended by 6 or less men since they tend to experience losing streaks quite easily. But they love taking places defended by 1 man because there easy to take and lead to little or no losses. Also I suggest not putting hundreds of men on one place to defend, spread them out! Or better yet ATTACK! If the games 1000 men versus 1000 the auto atk likely will win, cause in the end the probabilities go to the attacker in any large attack. And if he waits for it while attacking and follows my above attacking advice he'll probably end up with about 300-400 leftover when its 1000 versus 1000, but it would take a hell load of time and effort so it'd be rare for a player to take that time.
Anyway to do on this list:
Dice probabilities
Streak info
Additional suggestions from players?
PS: Yeah I hope my opponents don't read this -.- And I find I'm usually too lazy to follow my own advice.
1V1 Guide
Ok 1v1's mostly depend on the settings, im just going to go over the basic standard, flat, seq, unlim, nofog, I played this game: Game 8128766 and won by round 4 even though he got 2/3 of the only bonus that didn't have neutrals in it and got first turn.
What I did-First do my best to keep him from getting country bonus, In this case I had 2 places beside it with 3 men, if he had defense that was even on each side, I would suggest putting 1 on one side, and 2 on the other. This gives you 2-3 chances to break the bonus, if he gets bonus before you do generally its game over. When attacking try your best to always be attacking with 4 men and thus getting a 3-2 or 3-1 roll, this gives u a good shot at winning, as well 2 places with 5 and 4 respectively is better than 1 with 6 in most circumstances.
As well do not reinforce all your men to 1 place (in most circumstances), 1 man places are bloody easy to take, if you can try your best to leave 3-2 on each place. In corners and places where he can't attack though feel free to strip your forces down to 1 to use elsewhere. Remember to always take at least one place to get your card. Almost always AVOID KILLING NEUTRALS, it depletes your forces and not the enemies, as well it opens up places defended by neutrals that otherwise would be for your opponent. Total troop count is a huge thing in 1v1 games, watch it wisely. In large maps/games that extra 1 man a turn can be very useful, especially in games where bonuses cannot be held. Thus do your best to take over his 1 man places, remember when you take a 1 man place your not losing troops, your using 3 dice to his 1 and usually winning, and thus taking his troops out while not decreasing your total count. Remember to leave 2-3 on these 1 troop places if possible. And cards are mostly up to luck but do try your best to wait till you get a multi or blue color set, and try to get the places you have cards for, a 2 troop bonus is quite useful.
