29... Qxa3+ 30. Kc2
|
logically White's king will be in less danger when it is not in the center, but it doesn't matter how White continues, my queen just dominates the entire queenside. |
 
|
| |
|
|
30... fxe6
|
Rc8 will have devestating consequences now that the bishop isn't controlling anymore, so White's only chance is to sacrifice the inactive queen for my rook that is ready to attack, but that lets me catch up in material. |
|

|
31. Qxf8+ Bxf8
|
Here I have a queen and two pawns for two rooks, and my pawn on e4 is very strong compared to the other pawns on the board. The two rooks are often stronger than the queen in wide open positions where the rooks are coordinated and have other pieces aiding them, but here the rooks are not in any position to attack, and the rooks are horrible defenders. White would probably prefer to have a queen than the 2 rooks, since the queen would be a much better defender to oppose my queen. |

32. Bc1
|
My queen and bishop and pawn will reach full potential and complete the attack, despite the lack of attackers. White's king wouldv'e been much more vulnerable on c4 since I'd be threatening Qb4#, and if Bd2 in the position where White's king is on c4, then I'll have Qd3# |

32... Qa4+
|
33.Kd2 will lead to mate after 33...Qb3 (threatening Bb4 Ke2 Qf3#)
If 34.Ke1 then Bb4 35.Bd2 (try to find the other mates against other moves) 35...Qe3 36.Kf1 Qf3 37.Kg1 Bc5 or 37.Ke1 Qxh1 38...Qf3 39.Ke1 e3!! unstoppable mate |

33. Kb1
|
33.Kc3 loses to Bb4 Kb2 (if Kd4 then Be1 and Qxd1) Qa3 Kb1 Qb3 Ka1 Bc3
33.Kb2 loses to Bd6! and the bishop is invicible since the rook will be forked if it takes, and then the threat of Be5 is dangerous with the followup of more tempo checks.
Here I was worried that after Kb1 there wasn't enough material left on the board to complete the attack, but since White's rooks are horrible defenders, I can make them useless and it's almost like I'm up an entire queen. |

33... Qb3+
|
I will play e3 next move, stopping the Rd2 defense, |
|
| |
|
|
34. Bb2
|
After Ka1 e3, the rooks fail to defend, since disconnecting the rooks often allows rook-forking tactics. Either my pawn will advance to e2 and cause severe annoyance to the rooks, making it so that they cannot interfere with my bishop's completion of the attack on the h8-a1 diagonal, or I will win a disconnected rook. |

34... Ba3 35. Rd2
|
checking will give White a temporary sense of power, but it really just lets my king get a free move. |
|
| |
|
|
35... e3
|
Pretty much any rook move reaches the same doom. When there are material imbalances, you must use your imbalance to the fullest potential, and two rooks for a queen is not a good imbalance when the rooks are defending. 2 rooks tend to be a very strong attacking combo, while they are useless defenders. |
|

|
36. Rc2 Bxb2 37. Rxb2 Qd3+
|
The queen dominates the rooks, while the pawn is close to promotion, so it's pretty much over now. If Ka2 then Qd5 forks. If Kc1 then e2 and the king is badly placed, it stops the rooks from defending the promotion square, and allows the Qc3 tempo idea controlling the promotiong square, not to mention the king is more exposed to rook forks. Rc2 is also bad because of Qe4 threatening the rook, and there's the Qb4 idea that threatens the promotion square with tempo, so after e2 White really can't stop the promotion tactic, or he'll lose a rook. |
|

|
|
38. Ka1
|
White decides his king should be furthest from the action, but my pawn is too strong, White cannot save this position. |
|
| |
|
|
38... e2
|
Now Qc3 is an idea against passive moves, threatening promotion while pinning the rook. I can employ that idea after Rhb1 Qa3 Ra2 Qc3 and I promote. |
|
| |
|
|
39. Re1
|
After this I don't see a way to force promotion since my pawn is under attack twice. I'll have to lose the pawn and win with my pawn majority, but since White's rooks are terribly placed and not good attackers, this should still be an easy win. |
|
| |
|
|
39... Qd1+
|
what else? |
|
| |
|
|
40. Rb1 Qd4+
|
If Rb2 then Qa4 allows Qd1 and both rooks cannot defend the back rank anymore. |
|
| |
|
|
41. Ka2 Qd2+
|
I was starting to get into time pressure here, so I should just win White's pawns since his rooks are helpless defenders, and shouldn't be able to interfere since disconnecting rooks usually allows a forking tactic. |
|
| |
|
|
42. Ka3 Qa5+
|
This is better than taking immediately, since the king is forced to the b-file, now the rook cannot take pawn next move because of Qb5 |
|
| |
|
|
43. Kb3
|
The next several moves were made pretty fast, all I need to do is win White's last pawns and promote, this will be easy since White's king is far |
|
| |
|
|
43... Qxg5 44. Kc2 Qe5
|
White could try to defend this pawn, which is probably his last chance, but I will probably win this pawn eventually, and white probably wanted to get my advanced pawn off the board as soon as possible, but Rh1 was probably the best chance. |
