From: Upstate New York
Here's a summary of a checklist I use. I'm at work now, so I don't actually have it at the moment, but what you see below is a pretty close approximation. I've broken it down chronologically into stages I go through each turn. It's pretty mechanical, but it generally keeps me from forgetting to do stuff.
Prior Turn Overview
Check combat report.
Check operations report.
Check sig intelligence (pretty pointless as Japanese player, but slightly useful once every blue moon).
Check air losses screens.
Check status of ships damaged.
Check status of LCUs involved in combat.
Expand any factories I wish to expand.
Check factories that expanded in prior turns and confirm that they are repairing – adjust supply levels if they are not.
Turn selected factories on/off depending on pool levels.
Check R&D levels for aircraft being researched. Convert factories once current type has been developed.
Check Oil/Resource and Fuel/Supply levels at bases.
Alter stockpiling status and supply draw for bases that are overstocking or understocking.
Check ship availability window. Halt/Accelerate ships. Turn off shipyards (to conserve HI) if pools are high.
Form, disband, reroute TFs. I usually do this in three stages:
All “economic” TFs (cargo and tanker) are formed, disbanded and routed. In addition, any Air, ASW, minesweeping and/or SCTFs that are providing escort for these TFs are also formed, disbanded and routed.
Next, I go on to “combat” TFs and form, disband and route groups of TFs all participating in the same theater.
Finally, I take care of submarines.
Change leaders (TFs and/or ships)
Check damage/repair status.
Check for upgrades and conversions.
Adjust search and ASW arcs.
Adjust recon missions.
Adjust offensive missions (sweep, airfield, port, etc).
Adjust training missions.
Draw pilots to squadrons that need them.
Check training squadrons and send pilots to reserve pools once they have trained to
Check for upgrades and replacements (both done manually – I leave nothing to the AI).
Check air support levels at airfields.
Check for overstacking at airfields.
Adjust operations mode.
Adjust combat mode.
Check replacement/upgrade status.
GO THROUGH ENTIRE CHECKLIST AGAIN! (Nine out of ten times, I miss something moderately important the first time through.)
Triple check important things like KB, large amphibious TFs (and their supporting TFs), important unit upgrades and key factory progress.
E-mail turn to opponent. Double check to be sure the proper files are attached. Nothing’s worse than losing a day of real time due to attachment of the wrong files or failure to attach any files.
Hope this has been of help.
