I intended to give up my b, c, and d pawns for development of my two bishops. I've been successful with this in the past in blitz.
1. e4 e5
2. d4 exd4
This was a mistake. I intended to play c3, but it wored out anyway.
3 ... dxc4.
4. Bc4 cxb2
I give up two pawns for a large advatage in development. This is probably very unsound, but the advantage in development has proved useful to me in blitz games before.
5 ... Nf6
With the large advantage in development, I wanted to press as much as possible. With 6. e5 my intention was to press black's position while forcing his knight back. If 6 ... Ne4 then 7. Qf3 appears to get me a knight.
6 ... Ng8
7. Nf3 h6
h6 was one I hadn't anticipated for some reason, and hindered my plans.
8. Nb1d2 d5
8 ...d5 may possibly have been a mistake as he may not have seen the en passant. He may also have wanted to get his queen out, so I'm not sure, as it allowed him to do that.
9. exd5 ep Qxd6
10. O-O Be6
I expected the pin to be temporary with a 11 ...Ne7 or Be7. That was okay, though because I intended to follow with BxB and then Rb1 or Rc1. I would have had all my pieces in a position to bring them in to an attack then.
11 ... Nf6
With the triple attack on Black's bishop from the knight, bishop and rook I figured I was going to win at least a pawn, plus get my rook in a very strong position. Also on my mind was The possible fork between black's king and queen from the rook if black didn't block it.
12 ... Be7
Blocks the fork, but still allows my rook into a pressing position.
This may have been a mistake. Perhaps I should have played Bxe6, but I can't see why. This is a very open game at this point, and I thought that the two bishops would serve me better than a bishop-knight combination.
I chose to capture with the rook rather than the bishop to keet the black bishop pinned, and gain tempo by causing black to move the queen. My plan was to attack Black's remaining bishop, hoping to win it. I had forseen that the bishop could be saved, but his knight would have to move back to g8 to do this, and this seemed to lead to good things for me as I was far more developed than him.
14 ... Qd7
15. Ba3 Nc6
16. Qe2 Ng8
Forcing the King to move to d8. This takes away the castling possibility. I now have a stationary target to attack. If 17 ...Kf8 then 18. Rf6+ gxf6 (or Nxf6). Black can't play Bxf6 bringing his queen in because his bishop is pinned. After 18 ... gxf6 or Nxf6 then 19. Qf7++.
17 ... Kd8.
18. Bxe7+ ??
I was rushed on time but in retrospect this seems to be a bad move. I lose an attacking piece and allow him to bring in a piece to defend, and allowed his rook on h8 freedom to move down his back row. The idea behind this move was to take the Bishop out so 1.) it couldn't take out mine first, and 2.) it could not move to d6. I intended to bring my rook in the back row to d1 and attack his queen, and perhaps in the rish of blitz pin his queen. Definitely a miscalculation on my part.
18 ... Nxe7
19. Rd1 Kc8
Here, while I still had an advantage in development, I had lost the attack. I could perhaps force him to shuffle his pieces around, but I don't see any way to press him anymore.
20 ... Qe8
21. Qh3 Kb8
I seem to have an attack again with Na6 if I could only see it!!!
22 ... a6
23. Nd7+ ?
I was in a real rush on time here. I didn't even consider Nxa6+. That said, in retrospect after analyzing the position for a while, I don't know if it would have done me much good. For instance:
If black recaptures with his pawn then I seem to have the win. 24. Rb1+.
[FEN]rk2q2r/2p1n1p1/p1n1R2p/8/2B5/7Q/P4PPP/1R4K1[/FEN] (posted in following post)
If 24 ... Ka7 25. Qe3+ Nd4 26. Qxd4+ c5 27. Qxc5++. The other option is 24 ... Kc8 25. Rxe7+.
[FEN]r1k1q2r/2p1R1p1/p1n4p/8/2B5/7Q/P4PPP/1R4K1[/FEN] (posted 2 posts down)
From here it can proceed one of two ways.
25 ... Kd8 26. Rxe8.
[FEN]r2kR2r/2p3p1/p1n4p/8/2B5/7Q/P4PPP/1R4K1[/FEN] (posted 3 posts down)
Black can't play 26 ... Rxe8 because 27. Rd8 leads to mate.
So after white plays 26. Rxe8 Black must follow
26 ... Kxe8
27. Qe6+ Ne7
28. Qf7+ Kd8
29. Qe6+ Kb8 (or Kb7)
30. Rb1+ Ka7
31. Qe3+ c5
If instead of 25 ... Kd8 black decided to play 25 ... Qd7 then 26. Qxd7++.
If, however, instead of 23 ...bxa6 Black decided to play 23 ... Rxa6 then things would have looked different. I can not find a winning line from here, and things look fairly even.
Since, even after analyzing I can't seem to find anything except perhaps being able to force a draw after 23. Nxa6+ I don't feel too bad playing 23. Nd7+. After this black proceeds:
23 ... Ka7
24. Qe3+ b6
25. Qa3 Na5
Here I'm very short on time. I completely miss the threat on my bishop from black's knight.
26. Rxe7 Nxc4
27. Qg3 Qd8
Things have totally fallen apart for me. I have no attack left. h3 was just a rushed move because I was going to really have to rush just to keep the game going and I wanted to avoid the back-row mate.
and black wins on time.
I realize I made a couple of mistakes, however I felt I played this game reasonably well. I didn't see any outright blunders, and I had the initiative the whole time, but I don't see how I could have gotten trhough my opponents seemingly impenetrable defense. This is the sort of game I'm referring to, and I can't seem to figure out what I should have done to win this one.
To answer your question, I can't honestly figure out exactly how my opponent got out of that except by tactically blocking every threat I saw.
Sorry for the long post, and there's my analysis. Any help would be greatly appreciated.
