It seems that you play the Europe side much like you would in like revised or something. As UK, you would rarely build new fleet until the US is in the war. You should have most of your focus be on egypt/middle east. If you got a bid, try to have at least a sub in 98, and an art in sudan at minimum. UK1 Europe generally boils down to 1 of 2 major moves: 97 attack, or 92 stack. These both depend greatly on what germany does and maybe even what japan does round 1.
If you feel fairly safe from sealion, then usually 97 is the best. This helps if you can easily bring canadians over and if the cruiser in 91 still lives. Build 1 fighter and 6 infantry. Send eveything from 98 (except transport), malta fighter, london bomber and maybe 1 fighter to 97. If germany has air in south italy, bring the fighter, if not, then you should be fine. Try to sink as much of the german navy as possible with your surviving navy in the Atlantic. Sink 96 with your gib fighter and 91 cruiser. Ethe is also a major target, try to send the 98 transport with 1 tank 1 inf from alex, 1 mech from egypt, and the sudan units. The cruiser off India can bombard if you desire. If you really want to hurt him, you can use the india transport.
Try to preserve any planes if possible. Land surviving planes on malta (they can move to egypt next round). Stack london with air and scotland units (maybe take eire with the mech). Stack atlantic transports off canada if possible. Place all of build in london.
Now for 92 stack. This works best if you are either scared about holding london, or if you have surviving fleet in 110. This also keeps pressure on italy. The biggest worry is the german airforce. This REALLY depends on what survived germany turn 1 and where the german air is positioned. 92 stack usually entails either airbase in gib round 1, or algeria stack. Since italy will need to claim a landing spot for german air, you can either deny that landing spot, or have so much in 92 that germany cant kill it. This involves UK build an airbase in gib, and the rest being for london defense from a turn 2 sealion (really depends on the transports germany has). All navy that reaches in 92 while having the tac form 98 and the malta fig kill 96. Then, the transport in 98 can either take persia, or pick up the malta garrison and land on gib. If germany has no navy in range of gib, go for the persia option. Land as much of the london air in gib as you can afford to. This move preserves your fleet, threatens italian navy, and allows you the option to send everything home to stop sealion. Make sure you have a blocker so the italians dont attack your navy.
If the german air is too strong, make sure you hold algeria. Forget the Airbase and buy the 6 inf 1 fig. Land as much in algeria as possible without making UK too vulnerable. Stack fleet as normal.
If germany is going to hammer russia, Russia needs to by nearly all infantry(maybe some art). Russia will also need to retreat back to moscow. You can usually sit in bryansk for a little bit, but eventually you will be in moscow. Only counter attack when you can make it cost effective. You should have 60-70+ units in moscow by the end of russia turn 5 if germany is stacking bryansk. The UK needs to quickly contain italy, and start sending planes to persia. A factory in persia and/or egypt helps alot for this. 3-5 fighters turn 4 into persia can allow uk to reinforce moscow turn 5 if it looks like germany will hit moscow turn 6. Try to have russia get Iraq if at all possible. Watch our for sealion, make sure you dont leave UK naked too early.
If Japan is delaying his attack on UK/ANZ UK should be stacking burma unless he is worried about japan hitting india or killing his stack. Anzac should be able to fly his planes to java turn1, then india turn 2. This depends on the japanese position at the end of his first turn. The US should be focusing most of his cash on Japan for the first 1-2 turns with a little bit in the atlantic if you desire. Battleships and cruisers are virtually a waste of money they are good, just not as cost effective as the other naval vessels. You are much better off with subs, destroyers, and loaded carriers. Try to stack hawaii US turn 1 if possible, turn 2 at the latest(2 carrier 2 sub 1 destroyer buy works best for this). Retreat phil fleet to make queensland and fighter to guam. Turn 2-3 your fleet should of moved to queens with anzac ready to block if needed. Try to brign at least 1 loaded transport a turn down to queens so that you can more easily contest the dutch islands.
Anzac’s first turn buy varies. Usually its transport with infantry. But of Japan has a strong caroline fleet, try a fighter or a sub. When US is sitting in queens, try to supplement it with destroyers/subs for block and fodder. US can open the japan blocks for your subs/destroyers to kill transports in the dutch islands. If you can spare it, make sure you have enough air to scramble in queens n such. In some cases, Anzac can buy a carrier, but this is up to you. If you can put your 3 starting planes in java turn 1 safely, do it. This helps india A TON! And it can be 3 more planes in moscow if needed.
Try to have at least 1 loaded carrier in the Atlantic for US before u would stack gib. Take brazil, and try to have enough land units to prevent italy from taking gib or morocco if germany threatens your fleet. When the US moves to gib, have UK buy an airbase and land fighters on gib with the new airbase. 1 cruiser, loaded carrier, scramble, 2-3 destroyers and maybe a few subs can makes your fleet very hard to crack.
