Having one player on half or below aggression and one player on full will not work, as they will be run out. You must have the fully aggressive batsman's partner almost on full aggression as well for a partnership with great communication.
Don't worry about picking good players at the end of a season. Depth in a squad will keep you at full strength when a top players are injured or are on international duty.
-Whenplaying a one day game and batting first, play with slow aggression and play the whole 50 overs. When you finished the overs, do not click on "Continue". Save the game and exit then load that saved game. Then, once again save and exit and load the game. You can then score more runs and can play more overs until you get out. Do not try getting more than 1050 runs, as the game will crash. If you reach a score of 300 with five or more wkt remaining, try to play aggressive in case you do not get 1050 or more. Once you are all out, you only have to ball 50 overs and you can win. Note: This only works with one day and batting first. Also, load the same file that you are playing the series on; and when against a good team try getting 145 to 150 in first 50 with just losing one to four wkts.
-For more runs, press 4 so you will get lots of fours.
