This is one of the worst encounters.
The (red) creature has a +8 modifier to avoid being Bull Rushed. The green positions are where PCs can stand and see the monster. The yellow positions are where two PCs must stand... unable to even see the monster and thus participate.
Cheers!
You're right, it's terrible. I hate when a dungeon has a tactical challenge. All encounters should occur on an open plain with convenient cover.
If that's not possible, here are some things that you might try.
a.) Rotate fighters. Remember that cover prevents AoOs.
b.) Repeatedly attempt bull rushes. An enlarged barbarian may help.
c.) Use ranged attacs from the west-most green dot
d.) Squeeze into a space with an ally and take a penalty to hit (potentially a fun-inducing house rule)
e.) Use visibility-limiting effects (obscuring mist) and try to sneak past
f.) Break down the wall.
g.) Complain to designers about 5' corridors and tactical challenges.
h.) Leave the dungeon and go home.
I'm sorry, but I just don't see how a tactical challenge makes the game less fun. If the entire campaign consisted of this, I might ask for some variety, but if I was invading a kobold warren (or a thieves' den!), I would certainly expect cramped quarters and all the challenges that come with them.
