Took you mind posting a recap of your quest 1? Im using that deck and have a bunch of trouble with it. Got to quest 3 once but failed Hide Tests hurt me.
I wouldn't mind, but I don't remember all of the details either. Are you leaving the Riders in the staging area and not engaging them? You have to kill them-
Oh no, you can't kill them!
Ok, you have to drive them off as soon as you can. Save your Sneaky Gandalves for the 4 points of damage, engage, ready Sam, draw a card, play the Feint or Quick Strike you've saved (and maybe an Unseen Strike too if you don't have Gandalf) and send the Rider to the discard pile.
As far as Hide tests go, get a Fast Hitch on Sam and use him and Frodo to Hide. Discard cards to the Protector of Lorien (that you've put on Frodo) or play Frodo's Initiative to make sure you don't fail.
I have a pretty busy week ahead and probably won't play again until next weekend.
