1. d4
This was the second of two games played for the 31th GN Tournament.

 
1... Nf6
Called the Indian Defense, prevents e4, planning to eventually attack the centre by indirect means

 
2. c4 e6
The Nimzo-Indian Defense, opens up the dark-squared Bishop, ready to counter the possible Nc3 with Bb4, pinning the Knight

 
3. Nc3 Bb4
I pin the Knight, planning to eventually capture, giving him doubled pawns on the c file if he lets me

4. Qc2
Which he doesn't. Now Bxc3 is met with Qxc3, avoiding doubled pawns

4... c5
A gambit move, He is forced to capture or cxd4, hanging the pinned knight. I don't actually plan on re-capturing the pawn with my Bishop, as I would lose the Knight pin. He will be left with doubled pawns that I can eventually recapture with a development lead.

5. dxc5 O-O 6. a3
Attempting to chase the Bishop away, removing the pin

 
6... Bxc5
I decide to capture, regaining the lost pawn and attacking f2, a weak pawn

 
7. Nf3 b6
Protects my Bishop and allows developement of the White Squared Bishop, for an attack on the pawn at c4 or Knight on f3

 
8. Bg5 h6
Chasing the Bishop away

 
9. Bh4 Bb7 10. e4 Be7
I didn't like making this move, but I needed to get rid of the pin

 
11. Rd1
Putting pressure on d7

 
11... Nc6 12. Be2 Qb8
Planning to advance my pawn to limit the Rooks strength

 
13. O-O d6 14. Rd2 g5
The center is under white's control, and I have little play on the Queenside, so I decide to go for a kingside pawn advance, maximizing the strength of my Bishop's while limiting the usefulness of his Rooks.

 
15. Bg3 Nh5
Planning to capture, weakening his king and pawn formation

 
16. Rfd1
Though his rooks are well placed, my lone Bishop is enough to hold them off, so I can begin to bring my queen into play

 
16... Nxg3 17. hxg3 g4
Continuing my advance, while gaining a tempo forcing the knight to move

 
18. Nh2 h5 19. Nf1
planning Ne3

 
19... a6
In case he decided to advance his pawns on the queenside, making it harder for him to do so. This follows an important rule, if your opponent has little counterplay on the side your attacking, make sure he can't advance on another side before continuing your attack.

 
20. Ne3 Ne5
Freeing the Bishop and placing the knight in a solid position, ready to advance further
