11... Rb8 |
So I take the half open file first. | ||||||
| | |||||||
|
12. Rb1 |
Now white's defending the half-open file. More action is now on the Queenside. | ||||||
| | |||||||
|
12... Be6 |
Done in anticipation of ...d5, to open up the centre. | ||||||

Threatens my LSB, and possible fork of Queen and rook, unless I take with pawn. However, doing so would compromise my pawn shield. | ||||||

13... Qd7 |
Keeps centre control, links rooks, and defends LSB without risking my pawn shield. | ||||||

Nice. Opens up a flank attack against the centre, which also will open up space for his rook on the f-file. | ||||||

14... d5 |
Damn the torpedoes! Full speed ahead! I'm taking out his centre. I'm hoping to make a push Queenside. | ||||||

Ouchie. My knight is threatened. Still, I can get a pawn for it. I figure take the e4 pawn, which will let me use that DSB at last to take the pawn on e5. After this, I will be down even more material. | ||||||

15... Nxe4 16. dxe4 dxe4 |
This opens up space for my LSB, which after taking the pawn on c4, will allow me to attack white's defending rook, and possibly get it off that half open f-file, which is a potential threat to me. | ||||||
| | |||||||
|
17. Ncxe4 |
Now I'm still down a piece. Still, my bishops are going right through the centre, so it would be a shame not to get rid of those white pawns, innit? White could also move his/her DSB to c3 after this, protecting that pawn on e5, and offering up a queen trade. Since white is ahead in material, this would be a good play. A general principle of chess, is to trade pieces when you're ahead. | ||||||

17... Bxc4 |
Threatens his rook, which will allow me to take the e5 pawn in piece. Stops white from moving DSB, since s/he has to focus on the rook atm. | ||||||
| | |||||||
|
18. Rf2 |
Rook stays on the half-open f file. Only othe rplace was the e-file, which is also half open, but has a knight on it. | ||||||

18... Bxe5 |
Takes that pawn, also removes h2 square for white. Would like to place the bishop directly on g3, but it is attacked by the e4 knight. | ||||||

19. b4 |
I'm guessing this is an attempt to open the b file for white's rook. I do not want a trade, as I am down a piece (although I'm ahead in pawns for the moment). | ||||||

19... Rbd8 |
Now, I'm doubly attacking the white queen. If that bishop moves, I'm thinking something like 20.Be4? Qxd1 21.Rxd1 Rxd1 . Of course, I don't actually expect white's DSB to move, but I'm applying pressure down the centre now. Also, whites f file rook can't offer much protection to the queen atm, since my LSB is attacking his available squares. | ||||||

20. Rf6 |
Not sure why this move. The rook isn't going anywhere that I can see from here. Seems to be tempting me to take it with the DSB, which would lead to a devastating Queen-King check from the e4 knight. Nice try, but I am NOT moving that bishop. This, however, means my queen and king are on dangerous ground. | ||||||

20... Qd4+ |
So I prevent the forking attack, although I am still exposed here to Ne6, attacking both rooks. However, that would lead to cancelling white's piece advantage for me, after ...fxe6 | ||||||
| | |||||||
|
21. Rf2 |
Returns the rook, which technically wastes a tempo for white. | ||||||
| | |||||||
|
21... Bd3 |
Now, I'm thinking I have to get rid of white's knights, which are in bad positions for me. Too many forking opportunities have come up. I imagine he'll save the rook, which would allow me to take ...Bxe4. | ||||||

22. Nxc5 |
Nope, he wants that knight after all. Still, now it's not defending the g3 square! My DSB is suddenly in a dangerous position for him. Seems white was thinking 23. Ne4 to fork the rooks, but that would lead to 23. Ne4 fxe4 24. Nxe4 Qxf2 25.Kh1 Rxd2, which would be a huge advantage for me. | ||||||
