I imported the game so it's easier for everyone to analyze it.
My take on it is that in move 23, instead of moving a pawn, move your king to g2 in order to move the rooks to the h file.
Thanks daniel.
Here are my thoughts.
First, 36.R6h2 doesn't do anything. Don't play a move if it doesn't do anything.
Second, you were clearly winning after you broke through and traded. In that case, don't be so intent in finding checkmate.
On move 23, I like the idea of moving the pawn to c3 if it's used to close the queen side, that is to prevent counter play. In this position, it's tactically wrong as c5, exploiting the pin on d4 and the weakness of c3.
On move 36, you maneuver to place you most valuable piece in the front of the battery. As videos on "Alekhine's gun" will demonstrate, except for checkmate patterns, the most valuable piece belongs in the rear.
On move 28, moving the pawn to f3 looks like you want the e4 break, but this would be bad. Moving the pawn to f4, to prevent e5, is more correct.
On move 33, you should move the king out of the pin. Black by playing e5 and e4 would completely close the position, but white could still win by pressuring e6, by a bishop on g4, and h7. Black would get enough counter play by playing e5 and exchanging on f4. A possible invasion on the open e-file would keep white too busy to exploit the h7 weakness.
On move 43, you should exploit the weakness on c6 with 43. Be8 Rc7 44. g6 with Bf7 to soon follow. One of these pawns will soon fall, and black still has a useless piece stuck on h8. (I know this is more of an endgame mistake, but it's important enough to bring to everyone's attention.)
My thoughts:
36. Bxg6 if followed by hxg6 leads to mate in 2 with 37. Rxh8 forcing black to play Kg7 38. R1h7#
At the very least, Bxg6 will lead to a 3 point advantage by trading your bishop for a pawn and rook (lines bishop up with 2 rooks and the opponent can only move 1 out of the way).
@ggunter1 I thought I was keeping my eye on exploiting this pin. I guess I got distracted by the black pin on the f4 pawn. Thanks for catching this tactic.
lasers... lots and lots of LASERS. Black king no last long time when under assault by L A S E R
Unpinning 46 Ke2 seals black's fate. The threat Be6 is unstoppable, as 46...Rxf5 47 Qe6+ Rf7 48 g6 is the quietus.
