Netherlands 1798 getting noticably hard to beat

That never happen to me. Yeah on a rare case Denmark got pushed back and lost their capital, but they'll get it back once Prussia is weakened from the south

I have a method (problably not new) that allow me to end before turn 50 most of the times. I use my best generals for this, massena and murat, but the important thing is they have ambulance.
Turn 1: declare war on sardinia and swenden - bribe pruss and ottoman. (You should sent the legendery verhuell to swenden, so he can hit on sea swedish gen and after he dies, keep killing other swenden units or city defence)
Turn 2: declare war on porto
Turn 3: bribe ottoman and declare war on naples(so they will atack french ships and waste their streng there, when italy joins they will rape)
After this just bribe ottoman again and then bribe russia 2 times.
By turn 18 all the coalition except uk should be dead or about to, if they are still holding somehow, you can bribe russia one more time so they will join turn 21.
Now i will explain murat and massena job, since turn 1 you should focus on killing austria gens and weak units while sending them to prussia-poland border, when prussia joins support poland on holding pruss by killing pruss gens on east.
By turn 18 pruss should be dead or about to, so when russia joins (turn 18 or 21) your allies have an army huge enough to deal whit russia, you have to sent murat and massena to britanny and sail to ireland, the level 2 city on west ireland is the objective, after you take it, dublin and the other city are easy to take, whit ireland controlled go for north uk cities, your allies should be taking london and south cities at this point, so uk dies before turn 50, and mainly times before russ.

Thats all, sounds hard but you basically only control 3 units entire game, so is really fast to do. If your cap is on risk early turns you have 100 gold left whitout counting the gold you us for bribes, so you can make 2 militia to defend, or eaither sent 1 general back to cap to defend.
PD: like i said before, the third bribe for russia whit this method is possible but majority of times not necessary, so whit the money of this bribe you can fund or bribe allies like poland or italy but this wont make a real difference, also dont take any city before you done whit the bribes.
I will post images of the invasion of ireland later, it is easy just dont atract uk units when you are on sea.

Nice one, and this thread is now used for formulating bribe strategies lol.

Britain is the only nation you need to stand up against. 

Declare war on Sardinia and Portugal on turn 1 and bribe Prussia and Warsaw turn 1.
Bribe Prussia turn 2. (You can bribe Warsaw too but I don't really think it helps too much)
Bribe Prussia turn 5.
Bribe Ottoman turn 6.
Bribe Ottoman turn 9.
Bribe Russia three times.

Use your generals on the Grenadier and the heavy cavalry to stand up against Britain. The Ambulance (or the tent) is extremely useful for this. 

Wait how does that work? If one follow that order income will be exhausted by turn 2, and you need 5x income to bribe prussia the 3rd time on turn 5, not possible (and delaying would screw up timeline of bribing russia).
