A Chess-players thoughts on strategy in A&A

For purely defensive purposes, buying infantry cannot be beat. When you can swap in an offensive piece (artillery or tank) without decreasing the number of units you’re putting on the board, this is well-advised. The relative cost of units and their defending capability seems to be balanced such that quantity is quality.

For example, Russia starts the '41 version with 30 IPC. For that money you can buy 10 inf OR 8 inf and a tank, etc, etc… OR 3 fighters. If you benchmark every 30IPC purchasing combination against an attacking force of 4inf and 5 tanks (nearly a 50/50 battle with about a 2% chance of mutually assured destruction if you purchased 10 inf), the results are telling:

10 inf - 49% chance of winning [2 * 10 = 20 hit points or 20/6 = 3.3 average hits]
8 inf, 1 tank - 38% chance of winning [2 * 8 + 1 *3 = 19 hit points or 19/6 = 3.2 average hits]
5 inf, 1 tank, 1 fighter - 16% chance of winning [5 * 2 + 1 * 3 + 1 * 4 = 17 or 17/6 = 2.8 average hits]
.
.
.
3 fighters - 0.02% chance of winning [3 * 4 = 12 points or 12/6 = 2 average hits]

No combination of possible purchases perform better than 10 inf in this scenario.

However, when playing against a German Goering that likes to over-extend poorly defended fighters or bombers to gain a couple of IPCs, it’s nice to have the offensive capability to wipe them off the board. I have found this is best accomplished by pushing infantry forward (protecting your offensive pieces from overwhelming counter-attack) and keeping a mix of infantry, artillery and tanks within striking distance of the front line.

For offensive purposes, the best mix of units for the same 30 IPCs, baselined to a 50/50 battle of your 10 infantry against a defending 6inf + 1 artillery (approximately 1% chance of a draw):

10 inf - 50% [10 * 1 = 10 points or 10/6 = 1.7 average hits]
8 inf, 1 tank - 60% [8 * 1 + 1 * 3 = 11 points or 11/6 = 1.8 average hits]
6 inf, 3 art - 81% [3 * 1 + (3 + 3) * 2 = 15 points or 15/6 = 2.5 average hits]
5 inf, 1 tank, 1 ftr - 42% [5 * 1 + 1 * 3 + 1 * 3 = 11 points or 11/6 = 1.8 average hits]
.
.
.
3 ftr - 0% [3 * 3 = 9 points or 9/6 = 1.5 average hits]

For purely offensive considerations, the optimum combination of units in this scenario is 6 inf and 3 art at 81% chance of victory with 4 inf, 2 art and 2 tanks in close second at 80%. No combination of purchases which include a fighter score better than 53% (4 inf, 2 art and 1 fighter happens to be the specific combination in this case). Again, there appears to be a quality in quantity that supersedes just quality. It may go without stating, but if attacking a territory with an AA gun, the numbers will be even worse for the fighter purchases.

For the two scenarios above, the most balanced purchase (averaging the %won for each purchase in its offensive capacity and defensive capacity) is 7 inf, 1 art and 1 tank. This particular purchase is the second best defensive purchase (next to 10 inf) and only 4% less potent than the best offensive purchase (6 inf and 3 art).

I’m not against fighters or bombers, they certainly have their place I just haven’t found justification for purchasing them when playing as Russia (or Germany for that matter) - especially in the early rounds.

Similar conclusion are drawn with respect to naval units - more cost-effective units (subs and especially destroyers) are typically better than fewer high-powered units (battleships and especially cruisers).

Excepting special circumstances (such as no time to get infantry to a developing hot-spot on the map or needing to sandbag funds for a massive naval build against enemies squatting in your sea-zone) a good rule of thumb seems to be to maximize the number of attack/defend points your are bringing to the board, first, and spread over as many units as possible, second.

I play without national objectives regularly.  IMHO, the key for the Axis is killing Russia. I have found that the best way to kill Russia is to do a combined Germany/Japan land assault.  However, this cannot be done if USA and GB are offloading on France/NWE-  Germany cannot guard the Atlantic borders and keep pressure on Russia.  My solution was simple.  Establish a chain supply of Japanese fighters to France for defense (2 per turn as of turn 3)  This accomplishes two things: one, defends France effectively and,two, forces the Allies to build navy to avoid losing their transports.  This allows Germany to send roughly half of their land forces to the Russia front. ( build only infantry and artillery since IPC’s are scarce from turn 3 forward)  This slows Japan down but is well worth it to keep pressure on Russia from Germany.  Also,  move the Japanese fleet to protect Italy from invasion.  Allies can’t amphibious assault Italy with a massive combined Italian/Japanese fleet in sea zone 14.

I build a German bomber on turns 1 & 2 to keep Britain off shores till turn 3, then the bombers become useful in swapping territories with Russia.

triplea supports a game similar to AA50.

I always felt allies were stronger in both scenario. You just have to know how to play Russia agressively.

Definitely not. Allies are at a huge disadvantage in 41. Although Axis is at a huge disadvantage in 42. Its unfortunate that neither scenario is balanced.

Yes, economy is also a factor, however, I don’t like to view IPC superiority as a “margin of error”, or something that can be wasted.  I’m more of a “save for a rainy day” type of player.  I say, if your IPC advantage is really that great, wait a turn or two to build up your forces, then crush Germany in one blow.  :evil:

italy is way cool. here is why:

2 tanks in bulgaria/ epl or 2 inf in EPL with ftr in range will nullify the effect of a 1inf  russian blitzblocker in EUK and BEL. that means whenever theese units are in range, russia cant  press germany with north/south push from KAR,BST / CAU,UKR .  this eases fighting for gerrmany alot imho, as it ristricts the red army.

of course italy will have to get their NOs as often as possible but how you do that really depends on what british / US are doing.

but i prefer italy pumping out ground units as much as possible. maybe a trn+ inf round one is best. this way you get 12 units at end of turn 3 to africa.

imho if japan hits india j2 ,  he can easily set up a southern front against russia. much faster from here, than through china or up north :D much faster than wus attack. can pop out 5 units each turn at burma/india at j4. he doesnt need to defend theeseIC’s against chinese cannonfodder so 25 ipc each round go rolling to caucasus from then on, leaving japan enough for pacific/china

how fast can uk/us set up serious invasion of france/ italy ?

Mine is 9 I believe.
