I'm going to highlight a couple of things that have happened in the past few turns (where we have missed commentary, sorry about that). In this past commentary, I'm going to go in to depth about one or two things, rather than give overall commentary.
**COMMENTARY FROM THE PAST: Spring 1906**
Spring 1906: Turkey lost Sevastopol, but I don't think it was necessary. Let's recap the position:
Russia: Armies in Bud, Gal, Ukr, Mos
Turkey: Armies in Ser, Rum, Sev, and a fleet in the Black Sea.
Russia can double attack Sev, triple attack Rum, and/or cut any support from Ser or Sev. Bla is the only unit that can provide unbroken support, and so it feels like a 50/50 guess. Except, I think you can do better.
Let's assume Russia orders straight up attacks on the centers you've just taken from him (the most aggressive assumption). In that case, we have:
1) Bud->Rum
2) Gal->Rum
3) Ukr->Rum
(in each case the others support, and Mos->Sev)
4) Ukr->Sev s by Mos, Gal->Rum s by Bud
5) Ukr->Sev s by Mos, Bud->Rum s by Gal
6) Mos->Sev s by Ukr, Gal->rum s by Bud
7) Mos->Sev s by Ukr, Bud->rum s by Gal
The orders Turkey made were:
Ser->Bud
Sev->Ukr
Rum s Sev->Ukr
Bla s Rum
These defend successfully against all three Rumania attacks, in the hope that Russia doesn't attack Sev. In the Russian orders above we have:
1-3 = lose nothing
4-7 = lose Sev, forced disband
The Ser->Bud order is great, as it cuts support and opens Serbia for a retreat if Rum does get taken from Bud (although Rumania can't be taken with the rest of the Turkish orders). If Russia does somehow get into Rumania from Bud, then the Turkish position is strong - Bud, Ser, Bul, Sev, Bla.
I don't like the support with Rum- there is only one set of orders where Rumania isn't cut, which means that the order is likely wasted.
In this position you could have ordered:
Sev->Ukr
Rum->Ukr
Ser->Bud
Bla->Rum
This would give you:
1,7 = lose Rum, gain position
2,6 = lose nothing
3 = lose Rum and Sev, gain position (Russia is in Sev, Rum, Gal, Bud, you're in Serb, Bul, Bla, Arm and Ukr(!), on the other side of the line) From here, you can ensure you retake Sev, and have the opportunity to take Mos or Warsaw, or potentially pop the army in Rum (forcing an out of position rebuild). All of your units are useful.
4 = lose Sev, but get Ukr (Russia has Gal, Bud, Sev, Mos, you have Serb, Bul, Ukr, Bla, Arm). You can defend Rum, and retake Sev while guessing about Moscow and Warsaw.
5 = lose Sev and Rum, but get Ukr. Russia has Gal, Rum, Sev, Mos, you have Bud, Ukr, Bul, Bla, Arm. This position isn't great if Italy is hostile and in Trieste.
While we're here - I'm not a fan of Alb support Ionian - that's only useful if Italy uses two units to attack Ionian - but he either wasn't attacking, or would have hit with three. Instead, Alb->Trieste would have been much stronger - you could even have asked Italy for the bounce if you weren't ready to make moves he wasn't expecting.
Of course, sometimes in Diplomacy, even the best tactics won't help. I was discussing this position with peterwiggin, and he pointed out that there's a bigger strategy and diplomacy issue here:
"No matter what Turkey did, he was going to have a hard time taking Russia down without help from Italy, England, or both. In this case, if he had done what you suggested, he would not have lost Sevastapol, but he still would have been stalemated by Russia with Italy outnumbering him in the Med, and I'm not sure there's any set of moves that really prevents that as long as Russia doesn't move in a way that gives up Ukraine. The bigger problem for Turkey is just that his stab was not well-timed."
