Is there a way a Novice can sucker punch a master and win one game?

It isn't impossible to beat a master in a simul, you might get lucky...but that is what it would be LUCK. A week isn't really time to prepare but if you can look into some of his/her old games and see what she/he is most likely to play.  You might choose an irregular opening for surprise effect, but with just a week it will be hard to study it deep enough to make a dent.  I have played in several when I was in chess school in the Bulkans, and actually won once against the coach (a FIDE Master) but out of the 3 simuls, only 2 people actually won verses the coach...I mean, that is why they are the coach/Master.

I would NOT recommend a sacrifical line against a Master unless you know the implications COMPLETELY, once its off the board a Master will make you pay terribly. You say its graded, but winning isn't the way to get the grade, make him think harder at your board than anyone elses by looking deeper into the position then anyone else playing (I know empty platitude, but trust me, thats how you'll get the grade).

Do your best NOT to trade down, going to an equal endgame versus a Master is a GUARANTEED loss, to have a chance at even a draw you have to do it in the middle game, which means tactic, tactic, tactic.

Other than the empty (but valid) platitudes, I doubt you will find anything that will give you a leg up.

go to the bathroom alot they will make him nervous...

Get him to set a trap for you.

If he underestimates you, maybe you could play an opening with a well known trap he might use that will give you some advantage when you don't fall for it?

Actually, I can't think of one that would give you enough of an advantage so, I guess I'd try to just enjoy the experience.

If you just want to win your best hope would be to study traps (if he's a master it's very unlikely he'll fall for them but if your a novice it's your best hope, which is still next to nothing!). However, that seems like a waist. Why not play seriously. You will learn a lot from studying your game afterwards. Thus, by improving your chess you get just a little bit closer to his level of play.

What works well in a simul againt you?  Is it always good to play the sharp tactical stuff if you really want to win?

I don't think there is a problem with publishing the game as long as you made clear that it was a simul. What is annoying is the people who boast that they won against this or that master and then it turns out that it was in a simul.

Rabbit punch not sucker punch FTW!

I played and lost. Just tried my normal game and didnt do anything stupid. It would have been fun to pull off a sneaky with though  but i guess thats why their masters. 

So you didn't suckerpunch him?

Ditto on earlier posts suggesting that you muddy the waters.   Strive to complicate ... avoid trades that help him simplify because that's where stronger players eat weaker players for breakfast ... they can play out dry/simple positions as if they are on auto-pilot!

Play wild, but not stupid. You're very likely to lose, but go out fighting!

Statistically speaking,  masters still make analysis errors and visualization blunders (once in a while!) so it might be your lucky day but it just doesn't happen in simple positions. Keep telling yourself that!

I got very  lucky in an ICC simul a while back where an IM missed a shot.  Hope this helps inspire you!

Very convincing game Shivsky

I just watched the Fishing Pole:First Blood part1 video on youtube and I think it could be excellent tactic against average level master in simul. 1.e4,e5 2.Nf3,Nc6 3.Bb5,Ng4!? 4.h3, h5! here is the link one more time... very interesting indeed.

Well back in 2006 I was ICC 1704-ish and USCF 1400-ish...so not even an intermediate player either.  Still ... wanted to show what a wacky sharp opening (Albin) + some tactical muddying-up-the-waters can do against a "distracted" Goliath. 

Wow I didn't know that you are so strong player. May I ask your rating or do you have any title? No sarcasm here I'm genuinely curious.

move the peices around when he's not looking

 and (1) sneak extra Queens on the Board (2) move 3-4 times when he is not looking (3) Hire a GM to play under your name.

(4) Make his pieces mysteriously disappear.

In my opinion, select a positional opening where you can pressurize your master to make a mistake under time. 

If it is an outdoor event you could say that a bird went off with it...
