With your response on how Edmure should handle the defense of the Riverlands, it assumes that both Tywin and Jaime have to cross the Red Fork, in a reverse battle of the Fords. However your mountain pass answer would have Tywin come from Deep Den, loop around and hit the defenders along the Red Fork from behind at Pinkmaiden. Which would rupture the entire defense and leave the Riverlands troops strung out in a line from Riverrun to Pinkmaiden, with Tywin and Jaime hot on their heels.

That is a trenchant critique, and I’m glad you asked it!

Even in that scenario, I would still maintain that it’s a better strategy than sending 4,000 men to get butchered uselessly at the Golden Tooth and theng,  waiting at Riverrun until you get overrun. 

For one thing, it gives you 4,000 more men to hold the Red Fork, which means extra men available to go out scouting for Tywin’s army so as not to be taken by surprise, extra men available to defend Pinkmaiden aaginst Tywin’s army (preventing him from rolling up the line), you still have the option to throwing in the reserves to push Tywin’s second army back, and you have at least a decent chance of getting the army back to Riverrun in good order. Certainly much better chance than in OTL.

For another, it’s still going to inflict more casualties on the enemy than OTL: Jaime’s army still needs to cross the Red Fork and Tywin’s army is stil going to have to assault a well-defended castle. And wearing down the Lannister forces also means slowing them down, preventing that lightning march across the south that knocks out so many castles (including Riverrun). 

Hello! Got a question I’ve never seen tackled before. Here goes: Do you think Lord Tywin tried to recall Gregor Clegane’s attack on Beric Dondarrion? I think It’s in “Ned XII” we learn that Tywin indeed was pissed that Ned sent riders after him. This in turn would mean that he knew Ned was not in the party and the plan to capture him is failed right? So could he have sent a rider after Gregor to stop it but simply was too late? Thanks in advance and keep posting great stuff as always!

No, because Tywin was present for the Battle of the Mummer’s Ford:

“Father must have known that, because he sent out some men to oppose them, under the king’s own banner. He gave the command to some southron lordling, Lord Erik or Derik or something like that, but Ser Raymun Darry rode with him, and the letter said there were other knights as well, and a force of Father’s own guardsmen. Only it was a trap. Lord Derik had no sooner crossed the Red Fork than the Lannisters fell upon him, the king’s banner be damned, and Gregor Clegane took them in the rear as they tried to pull back across the Mummer’s Ford. This Lord Derik and a few others may have escaped, no one is certain, but Ser Raymun was killed, and most of our men from Winterfell. Lord Tywin has closed off the kingsroad, it’s said, and now he’s marching north toward Harrenhal, burning as he goes.”

So it is absolutely not the case that Tywin tried to recall Gregor; rather, Tywin was the anvil to Gregor’s hammer, and the two of them were working in concert to hit Beric Dondarrion’s forces from two directions at once. Yes, Tywin was pissed that Ned wasn’t there in person so that he could force the fait accompli, but that wasn’t enough to get him to call the whole thing off. By this point, he’s already committed to war against the Tullys as revenge for Tyrion’s capture and isn’t blinking at the idea of attacking the King’s banner in the process.
