The score is 6 to 8 in your favor.
is the upcard. You sit in 3rd seat. Your partner is a skilled player and he passed. 2nd sat passed. You hold the following in your hand: 
. Do you pass or order the dealer up?I ran a simulation of 10,000 hands with these cards fixed and the rest of the cards random, and the result was an EV of -0.24 if I order the dealer up (41% euchres) and +0.28 if I pass (I euchre the dealer 43% of the time - many aggressive dealers loathe turning over a bower, and will call with marginal hands). [Note that the euchres don't add to 100% because the play will differ depending on who orders up, notably the opening lead]. I looked at how a bunch of the hands were played and it seems reasonable, it's just that dealer is in a very strong position. I have found that in general it is poor decision to call up a bower from 3rd seat without a much stronger hand than this (maybe 3 trump with L and A, and an off-suit A, 2-suited).
But the quiz results say I should order the dealer up.
Note that I understood "your partner is an experienced player" to mean that they will lead trump on the first trick, if possible. Just in case I was mistaken I tried having 1st seat lead their worst card on the first trick, but the results didn't change.
What am I missing? If this is an example of donating to keep the opponents to bid a successful loner for the win, shouldn't 1st seat be doing that?
