The English Kings. Lines for my level of play are similar against KID or this opening. My pawn breaks are b5 or f5. The dark squared bishop becomes evil on b4 or g5 after a pawn break has been played. The KN belongs on e2 (I ignore this sound advice)

Blacks development looks excellent. For me, e4 would complete my Botvinnik system with the triangle in the center. (Minus the N..we'll get to that). However I took some time to analyze this position and decided that the B on b6 is problematic - I don't like it there in a Botvinnik kingside push. I asked myself what can I do to punish this different placement. All I could come up with is a frozen b6 pawn. So I decided to go for a queenside push - b5.

Ne1. Have to talk about Ne1. Generally speaking the KN doesn't belong on f3 in Botvinnik systems. However, I delayed playing the Botvinnik and chose in the end not to play it at all. I was ready to transpose into a staunton - but my opponent did not oblige. Now after the b5 push (and a strange Rxc6 recapture..) I wanted to open up tactics on c6 and b7. Ne1 looks hidious but it is not all that terrible - Nc2 certainly gives the dark squares a lift, and bounces will on a queenside advance.
GP34 talked about a swap of the Rc6 and Bg2.. As white I generally accept this. I would certainly have accepted in this position, with intent to play h4, Ng2, an eventual Bg4, Qc2, Rfd1 and bounce the knight up a rook protected open file on the queenside. I would be playing with absolute intention of not allowing a release of central tension.

Black has lost. Mr. Pawn was definitely better with his analysis on Rxc6, and leaving it there for the exchange of the bishop. Now white just has to keep a cool head (That wasn't easy in my first OTB rated USCF game).
20. Nc2 a6
21. Nc3 Bd4 22. Nxd4 exd4 23. Ne4
Ne4? Terrible mistake. Worse is following through with it. Bxe4 on recapture hangs h3. Trading off is good, getting stressed a bit and trying to play principled chess without paying attention to the tactics..is unforgivable.

After Rxc1 I was eyeing Qc7 as the best continuum. I didn't mind losing the pawn and I liked the scope and attack it presented. I liked the idea of Qxb7 and Rb1 putting the rook on a light square with a pawn blocking any long diagonal attack on it. I should have played exactly along this line of thinking...but after Nxd5 my eyes got big with a pin to the king. I should have stayed with my original analysis. Qc4 was a good, but lesser move.
29. Qc7 Nxd5 30. Qc4 Qd8
Now what? Its ugly. Qc7 was better.
e4 allows e.p and things get uglier - still winnable ending, but much more complicated without any reason at all.
No need to look any further.
