I wanted to share with you a King's Indian Game with a nice attack Queen's side without Queen
So the game followed a main line to reach the position bellow after 1. Nf3 Nf6 2. c4 g6 3. d4 Bg7 4. Nc3 O-O 5. e4 d6 6. Be2 e5 7.
O-O Nc6 8. d5 Ne7 :
r1bq1rk1/ppp1npbp/3p1np1/3Pp3/2P1P3/2N2N2/PP2BPPP/R1BQ1RK1 w - - 0 9
In this position the 3 main options are 9.b4, 9.Ne1 or 9.Nd2.
I chose 9.b4 to gain space on queen side. After 9...a5 I chose 10.bxa5 instead of 10.Ba3.
r1bq1rk1/1pp1npbp/3p1np1/P2Pp3/2P1P3/2N2N2/P3BPPP/R1BQ1RK1 b - - 0 10
After 10...c5 11.Ne1!? Rxa5 12.Bd2 Black has a cramped position.
2bq1rk1/1p2npbp/3p1np1/r1pPp3/2P1P3/2N5/P2BBPPP/R2QNRK1 b - - 0 12

12...Ra3!? seems a novelty and may be considered.

The point of the spear after 11.Ne1 13.f3 and the 14.Nd3 :
2bqnrk1/1p2npbp/3p2p1/2pPp3/2P1P3/r1NN1P2/P2BB1PP/R2Q1RK1 b - - 0 14
After 20...Nf6 :
3q1rk1/1p1bn1bp/3p1np1/2pPp3/2P1Pp2/1PNN1P2/3BB1PP/Q4RK1 w - - 0 21
It's time for white to launch the deadly Queen side attack.
After 24.Nxb4 remember that knight that went from f3 to e1 then d3.
5rk1/1p1bn1bp/3p1np1/3Pp3/1NP1Pp2/2N2P2/3BB1PP/R5K1 b - - 0 24
After 28.cxb5*
R7/1pr1nkbp/3p1np1/1P1Pp3/1N2Pp2/5P2/3BBKPP/8 b - - 0 28
In this position black played 28...Nd7 surely with the idea of Nc5 afterwards.
R7/1prnnkbp/3p2p1/1P1Pp3/1N2Pp2/5P2/3BBKPP/8 w - - 0 29
Now do you find the killer move ?
29.Nc6! the punch !
R7/1prnnkbp/2Np2p1/1P1Pp3/4Pp2/5P2/3BBKPP/8 b - - 0 29
After34.Ba5 white still has to eliminate the b7 pawn.
R1n5/1p1nk2p/3pNb2/BP1Pp1p1/4Pp2/5PP1/2r1B2P/4K3 b - - 0 34
Black resigned after 34.Bd1
8/1R1nk2p/3pNb2/1P1Pp1p1/4Pp2/5PP1/2r4P/3BK3 b - - 0 39
Of course I played this game with heavy computer assistance, this does not reflect my playing skills.
