26... Nf8
the logical response.. black is close to getting his game back albeit a pawn down

 
27. Rf1
The rook gets posted here with the intention of pressurising this file in the near future

 
27... Qd8
? The mistake I was waiting for. Ne6 is better, widening the influence of blacks knight and contesting key kingside squares. Here black aims to defend his f pawn, but critically weakens his 7th rank

 
28. g5
My favourite move of the game! Of course I could have pushed this pawn previously to crack open blacks kingside. The pawn is untouchable for the time being, oweing to the discovered threat against blacks bishop.

 
28... Nd7
holding f6 as a strong point, however apparently overlooking a further advance to g6 which is now on the cards

 
29. Qd1
I was tempted to play the immediate g6. however after g6, Be6, Qd1, Kg8, Qh5, Re7, Qh7 , Kf8, Qh8 , Bg8 and black holds. So I opted for this quiet(ish) move, putting more pressure on black to make his best move to alleviate the pressure, while maintaining the strength of my position.

 
29... g6
Kg8 I felt was slightly better here. If this was played then I'd respond Qg4. From this position the response Qg4 would be met by f5, which would help black.

 
30. gxf6
But of course I played gxf6... which leaves black with a dilemma.. Retake and face a concerted attack. Or ignore a dangerous passed pawn with mating prospects near the king

 
30... Nxf6
opting to capture... his black squares near the king are now a major weakness

 
31. Qb1
I had a lot of options here , and chose a double attack against the b and g pawns. Again this puts the question to black. For example if he plays b6, I respond with Bg5, pinning the knight and queen.

 
31... Qd6
The options arent great here for black, possibly kg7 or b6 would be an improvement. Black possibly anticipating bd5 preemptively aiming to avoid this possibility

 
32. Bf4
My eye is turning to other black squares, and drives the queen back, gaining a likely tempo in the process. Now threatening the incisive Be5!

 
32... Qd7
Queen aims to move off the threatened black squares.. only to hop onto another bad square. As this results in an ugly skewer on b5

 
33. Bb5
The skewer in question, that aims to exchange with the rook once blacks queen steps asside. Although my white bishop is powerful, swapping to the rook wouldnt detract from the continuation of this attack, and it also serves to continue to hound blacks queen

 
33... Qe6
Black plays his final move, with the misfortune of blocking the rooks control of the e file, and then with good reason promptly resigns... My continuation would be Be5, and black is powerless to avoid dropping the knight and further material.. a sample line might continue.. Be5, Qc8, Bxe8, Qxe8, Rxf6, Kg8, Qxb7 and black cannot hold out for long against whites threats. I hope this annotation added something. I posted this match, as I believe the play here is reasonably accurate, and shows gradual pressure being applied to achieve a winning position.
