Good suprise opening?

Another player and I have been playing some games in order to determine positioning in a ladder. I am in the lead (by a win) and am looking to finish strong. My main opening (Spanish Game) I used as white before against this player, and now I want to finish this series with a suprise opening (preferably non-e4) to throw him off. I am thinking of the English Opening, but would like some tips as to other possible openings. Keep in mind this is club play, so my opponent does not know many obscure opening lines.

 Thanks!

Reti 1.Nf3 d5  2.c4

or London 1.d4 Nf6  2.Nf3 followed by 3.Bf4 

It's probably best to stick with what you know, unless you have time to play a few practice games against other opponents before your club match to get used to a new opening. I always stick to what I know when I really care about the results and only try new openings in practice games.

That's good, sound advice. A player is more likely to have better results playing openings in which he/she is familiar rather than new stuff. Even at the GM level, you never see guys playing new openings on the fly. Unless a player has done some serious home-preparation, they will usually lose with a brand new opening.

That would be my suggestion (Grob's Attack).

But some other ones are 1. f4 (Bird Opening) which often leads to a reversed Dutch Defense, one of my favourite positions. 1. b4 (Sokolsky) which often follows  1. ... e5 2. Bb2 or 1. ... d5 2. Bb2 and there are a few traps, but in the trap department, I really suggest the grob (g4)

The ones I have had most success with are 1. d4 1. Nf3 and 1. a3! But Nf3 is unsurprising as is 1. d4. 1. a3 can be a bit disquieting to the opponent and there's nothing wrong with it technically. If 1. ... e5 then 2. c4 is a very good response. Personally, I don't like 1. c4 because of 1. ... e5 but that's probably just me. Lastly, even though you don't want e4, the King's Gambit is great.

As black the Old Benoni (1. d4 c5) is fun, as is the Dutch defense (1. d4 f5), both of which I suggest. 1. ... a6 against 1. e4 I've been playing around with lately, which after 2. d4, I play 2. ... b5 and then often Bb6. But I think it a little risky for tournament. Otherwise against e4, I don't reccomend the Scandinavian, but that's just me; you might want to play with it. I have heard good things of the Evans gambit, but I haven't played it.

Nakamura is the exception to your comment, fischer.  He's played some very uncommon open against other GM's (with varying degrees of success). 

I'd nominate the Bird for white.  For black, you have an array of unique options.

This fischer guy knows what he is talking about.  Don't play something you don't know.  Then you don't have the chance that the other person actually knows the opening(which you just started looking at) and then you are at a disadvantage right out of the gate. 

 But even then, you can be sure Nakamura does plenty of home study before playing the oddball openings. It just goes back to my original point - Don't try to learn a new opening in 10 minutes and then play it in an important game. Either take the time to really learn the new opening well, or else stick with the openings you really know well.

Thanks for the feedback everyone!

 And if anyone cares, it is in a week, so I am going to play and study the openings mentioned in the meantime.

Why thank you!  

Not really. The last statement in my post said, "Unless a player has done some serious home-preparation, they will usually lose with a brand new opening."

And I can guarantee you that Nakamura has done his homework on any line he plays.
