Picking a King's Indian Variation

I have been playing the Samisch, but am getting tired of it.  I was wondering if anybody had any opinions of a new variation for me to play as White.  Thanks in advance, and your reasoning behind the line you suggest will be appreciated.

Lots depends on your style. I personally like the bayonet as i do not like to wait and see blacks attack

What do you think of the 6. ... c5 line from the White side of the Samisch?

Well, the 6. ... c5 variation was indeed what was boring me about the Samisch.  I did not even consider ignoring the gambit.

Be3 variation instead of Kne1 or Knd2 which are long and people tend to memorize those lines.

The Be3 always draws black to kng4 thus the Bg5,f6, Bh4 or Bc1 with Bishop back to E3 to hold the tension.

I don't understand what you mean.  A diagram would be very helpful.

Four Pawns attack:

Samisch:

Averbach:

Main Line:

I think you got the Main Line wrong.

And for the averbach you should probably show 6. ... c5

I recommend the Gligoric Variation:

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.Be3 and now if 7...Ng4 (main move), then 8.Bg5 f6 9.Bc1 (9.Bh4 is an option, but 9.Bc1 has some newer ideas in it) Nc6 10.d5 Ne7 11.h3 Nh6 and now, instead of the "old" 12.g4, play 12.h4!  The opening of the h-file is a bigger problem for Black than the opening of the g-file, and what Black has to do to avoid it is just as ugly for him!

I think the Gligoric is a little too theoretical for my taste.

Well, if the Gligoric is too theoretical, then I recommend not going into a King's Indian defense at all, and play 1.e4.  Lines like the Saemisch, Fianchetto, etc are even more theoretical.  The Gligoric has less theory than the main classical or Petrosian.  The other advantage with the Gligoric, and the reason I recommended it, was that many Black players are so used to storming that Kingside that they are just weakening themselves if you haven't castled yet.

By the way, if you really want to talk theoretical, try playing what I played for the longest time.  The Four Pawns Attack!

The variation that I meant and is fun for white and seems to catch black off guard (Black seems to be expecting the NE1 or ND2 variations in the KI.) I would castle on move 7 for white though.

"... the Gligoric is not easy to play for White because Black has eight (!) main continuations.  Because of all this, White has to be ready to handle the theory of several lines, whereas Black only really needs to know one.  White also has to be prepared to play with several different pawn structures.  This makes it difficult to play compared to, for example, the Petrosian Variation, where White really only has to understand one structure.  Because of this demand on the White player, the Gligoric is more popular amongst titled players than it is at other levels."  

Quoted from David Vigorito in his book, Attacking Chess The King's Indian Volume 1.  This pretty much shows that your comment wasn't quite accurate.  Sorry, I never even read your comment until today, this is the reason for the delayed response.

Rapidwurst, isn't that intensely theoretical?

You can also try the Bg5 Samisch. It's not the most dangerous thing in the world but you can use the same setup against the Benoni too and save time having to find something against both of these openings.
