I have found the game types played in Issei's and Sairaog's rating games. Rough translation of course.

Lightning Fast

In the rule of the rating game, the rule used in the shortest time limit and the narrow field. Therefore, it is considered to be a short-term decisive battle for early poetry (blitz). With a time limit of 1 hour, it is better for you to beat the opponent's "king" first. If it can not be defeated, the win / lose is decided by the total bridge value of opponent team player who defeated by the end of the match.

One Day Long War

With the very opposite rule of "Lightning Fast", a very long time - a limit time of 1 day is set, and during that time, the rule to move around the field that is too violent, to defeat the opponent. Because the field which is too large is prepared, the enemy capability becomes important and patience and stamina are necessary.

They are in order of appearance so Lightning Fast is what Sairaorg and Cao Cao plays and One Day Long War is what Issei and Sona plays.
