Wow, this was a great, energetic game with many powerful tactics

By finding the excellent move 31.Qh7!!, threatening backrank mate and, while black has to defend against that mate, by winning black's queen with the skewer 33.Qg8+ Ke7 34.Qxa8, you decided the game in your favour, keeping the upper hand in these wild complications After 31.Qh7, black was left with no chance to save the game.

I also liked your energetic queen sacrifice 36.Qxa5 followed by 37.h7, and black cannot stop the h-pawn from getting another queen, which was a strong way to easily convert your advantage.

If black had been able to foresee the surprise move 31.Qh7!!, he might have been able to avoid playing 30...Rc6? and to try

30...Rb5 (keeping covered the square h7 with the rook on h6, so that the white queen cannot enter devastatingly there) This would have left black with some advantage.

Or maybe, if black was really in the mood for tactics and really mastering it, he might have been able to choose the very interesting move

30...Re6!? , intending to answer 31.Qh7 with a sacrifice: 31...Rdxe5+!!, for example 32.dxe5 Rxe5+, and now white would be forced to retreat the bigshop from g5 (which is covering e7 and thus helping to threaten the back rank mate) with 33.Be3 Bxc4+, and black would be winning.

White could not really try anything like 33.Kd3 (33.Kf1 Qh1#, 33.Kd1 Qd5+ ...) because the mating attack of black's centralized pieces becomes irresistible after 33...Qd5, for example 34.Kc3 Qxc4+ 35.Kd2 Re2+ 36.Kd1 Qd5+ 37.Kc1 Qh1#

Another nice tactical opportunity in this game arose earlier, when black chose to wildly complicate matters by putting his rook on b5, defending it dynamically with the knight fork threat and the pinning threat:

after 26...Rxb5 27.Bxe6! (you nicely eliminated the knight which was threatening the fork) 27...Qa8!? (an interesting try by black to still keep matters complicated, even though you have already seen through and refuted the main point of black's intended combination),

you probably saw that your bishop is attacked, and that you cannot take immediately on b5 because black could then pin the queen with 28.Qxb5? Ba6!

But instead, there is the beautiful move

26...Rxb5 27.Bxe6! Qa8!?

28.Bxd7+! intending 28...Kxd7 29.Qxb5+! and white wins that rook on b5 with check, giving black no time for the Ba6 pin

A very rich tactical game, and you came out of all these complications winning, because you mastered them better than your opponent :-) The decisive tactical blow was your excellent move 31.Qh7!!

oscartheman, 32...Rh6 33.Qg8# is mate

Kupov, the thread opener certainly does not need to be motivated; he is happily sharing some nice and unusual combination with us :-)

Noone claims that this game was perfectly played on each move; the two main blunders (28.Bxd5? instead of 28.Bxd7+ and 30...Rc6? instead of 30...Rb5 or 30...Re6) that turned around this game back and forth were the moves that made the nice and surprising Qh7 possible.

Very nice game, even though there were some mistakes (shown above) :)

Thanks!
