16... Bxf7 |
Getting the pawn back, but more importantly, challenging the c4 square and the whole light square diagonal. | ||||||

17. Rd1+ |
Driving the king away. Note that 17...Nd5 18. Rxd5+ Bxd5 19. Qxd5+ Kc7 20. Bxe5+ is not at all good for black, as the white bishops and queen are deadly against the exposed black king. | ||||||

17... Kc7 18. Bxe5+ |
Picking up the sacrificed piece, but still down a knight, with two pawns to show for it. But the initiative is the main fight here. | ||||||

18... Kc8 19. Qd3 |
Probably not the best move. The point is to put pressure on d7 and d8, so the Be5 is immune to the queen. I totally missed black's terrific response. | ||||||

19... Nd7 |
! Attacking the Be5, putting white on the back foot for a minute and also shielding d8 for the king. | ||||||

When in doubt, but a rook on the 7th - knight is double pinned now - to the king and queen! Be5 is still immune. | ||||||

Unpinning the knight, and renewing the threat on Be5. | ||||||

22. Qb5 |
Reinstating the pin on the knight and threatening to infiltrate via b7. But doesn't this allow...?? | ||||||

Yes, black will get the queens off, and one would think the attack would be over, but white wants the exchange on his terms... | ||||||

! Putting the question to the queen. | ||||||

23... Qxb5 24. Bxb5 |
And the LSB replaces the queen and keeps the pin. | ||||||
| | |||||||
|
24... Rd8 |
? I think Be6 is a little more flexible, although black does still have issues, most notably ideas like Kf2, Rd1, f4, f5 and or e5, e6 in some variations. The rook is now threatened by the DSB. | ||||||

! I'll allow myself an exclamation mark for this move, as removing the b-pawn opens the a5-d8 diagonal while clearing the rook at the same time. | ||||||

25... Bc5 |
Black moves to interrupt with Bb6. | ||||||

Did not like Bxg7 here as Black's rook gets active after Rg8. This forces the Black bishop to move again to a worse diagonal. It needs to stay on the a3-f7 diagonal to prevent against Bxg7 followed by Bf6, eliminating black's rook from protecting the knight (Black needs to have Be7 as a resource if ever white plays Bxg7). So Black must leave the a7-g2 diagonal, which will allow Kf2, activating the rook while keeping guard of g2 in case the g-file opens for black. | ||||||

26... Be7 27. Rxa7 |
Creating two outside passed pawns, and protecting the a2 pawn from the black sniper. 27. Kf2 a6 brings black some reprieve. Now, the pin is still in tact. | ||||||
| | |||||||
|
27... Bf6 |
Black continues to exchange the attacking pieces. | ||||||

28. Bxf6 |
White accepts, since white's bishop did not have a promising future anywhere else. | ||||||
| | |||||||
|
28... gxf6 29. Kf2 |
Now installing the Rd1 threat. | ||||||
