Here is the second part of my team matches vs Kalyan. In this game I have been able to come from behind after an early game blunder and still managed to checkmate.  | 
| 
 | 
1. e4 e5 2. c4 
 | 
Taking space in the center, but has the inconvenient of weakening the the black spaces in the center (d4 e5). | 
   
    | 
|   | 
| 
 | 
2... Nc6 
 | 
Normal developpement | 
   
    | 
|   | 
| 
 | 
3. Nc3 Bc5 4. Nf3 d6 5. Nd5 
 | 
This has to be considered as a mistake, moving a piece twice in the opening without a good reason. | 
   
    | 
|   | 
| 
 | 
5... Nf6 6. d3 O-O 7. a3 Bg4 8. Be2 Nxd5 9. exd5 Nd4 
 | 
Nd4? I thought about a series of exchanges 10. Nxf3  Bxe2 but did not see 11. Nxe2...  | 
   
    | 
|   | 
| 
 | 
10. Nxd4 Bxe2 11. Nxe2 
 | 
I'm one piece behind... At this moment I told myself : "OK, you made a mistake, just focus back on the game now". I decided to take some expansion on the king side, where he will most likely castle. | 
   
    | 
|   | 
| 
 | 
11... Qf6 
 | 
Threatening Qxf2  | 
   
    | 
|   | 
| 
 | 
12. O-O 
 | 
Now, the F pawn is pinned to his king by my bishop. | 
   
    | 
|   | 
| 
 | 
12... Rae8 
 | 
I'm now planning to push my e pawn and eventually move my queen and advance my f pawn. | 
   
    | 
|   | 
| 
 | 
13. Ng3 Bd4 
 | 
Pinning his b pawn to his rook and keeping his bishop in c8 to defend his weak pawn. | 
   
    | 
|   | 
| 
 | 
14. Nh5 Qg6 
 | 
Now I can push my f pawn forward. I don't know what white was trying to do with that move. It just allowed me to go forward with my plan. | 
   
    | 
|   | 
| 
 | 
15. Qf3 f5 16. Ng3 e4 17. dxe4 
 | 
I think Qd1 was better | 
   
    | 
|   | 
| 
 | 
17... fxe4 
 | 
Threatening his queen... | 
   
    | 
|   | 
| 
 | 
18. Qh5 Qf6 
 | 
Avoiding the exchange and putting even more pressure on f2. | 
   
    | 
|   | 
| 
 | 
19. Rb1 
 | 
Finally freeing his bishop | 
   
    | 
|   | 
| 
 | 
19... Bxf2+ 
 | 
Getting some material back but pinning my bishop to my queen. Still, white needs to move his king and it allows me... | 
   
    | 
|   | 
| 
 | 
20. Kh1 Re5 
 | 
1. To drive his queen back and... | 
   
    | 
|   | 
| 
 | 
21. Qe2 e3 
 | 
2. To lock my bishop in f2. | 
   
    | 
|   | 
| 
 | 
22. b4 
 | 
He is now planning Bb2 to attack both my rook and my queen on the a1-h8 diagonal. | 
   
    | 
|   | 
| 
 | 
22... Qh6 
 | 
Countering his next move and threatening his knight, h pawn is now pinned to his King | 
   
    | 
|   | 
| 
 | 
23. Qg4 
 | 
Protecting the knight and planning Qh3 to try to exchange the queens. |
