1.e4 c5 2.Sf3 d6 3.d4 cxd4 4.Sxd4 Sf6 5.Sc3 g6
The Sicilian Dragon. In the "old" days a feared weapon amongst white players, nowadays it's black who struggles theoretically

6.Le3 Lg7 7.f3 0-0 8.Dd2 Sc6 9.0-0-0
deviating from the main line which is 9.Bc4

9...d5 10.exd5 Sxd5 11.Sxc6 bxc6 12.Ld4 e5?!
Perhaps a little harsh to call this move doubtful. After all, it is the main move in this line. But, I'm convinced that 12...Bxd4 is clearly the safer option for black. However, for a dragon player it's not always easy to give up the fragon bishop!

13.Lc5 Le6 14.Se4
The white pieces go to nice central squares and, for now, we see little of the classical dangerous dragon attack against the white king

14...Te8 15.h4 Sf4
[alternatively, 15...h6 planning to meet h4 with g5 to close the kingside 16.h5 g5 ]

[16.g3 the alternative line 16...Dxd2+ 17.Txd2 Sh5 18.g4 Sf4 19.h5 has been played many times in correspondence, and with good results for white. But I was not too happy to trade off queens at this point]

16...Ld5 17.h5
[tempting to play 17.c4 but black has a ressource 17...Dc7! now white cannot take the bishop because black the has a double attack on white's bishop and knight on the next move 18.cxd5 cxd5 ]

[17...Sxh5? 18.c4! now the bishop on d5 is lost - no Qc7 trick available for black now]

it's evident by now that the game is being played completely on white's premises. Objectively, the advantage may not be that big, but black really struggles to establish counterplay

18...hxg6 19.Sd6 Te6
[clearly, the alternative was 19...Dg5 20.Kb1 Ted8 The rook is better placed on d8 than on e6]

20.g3 Txd6?!
[I was expecting 20...Sh5 21.Sxf5 Dg5+! 22.Se3 Tb8 after which black starts creating some counterplay. The position is very complex and difficult to evaluate]

21.gxf4 Td7 22.fxe5 Lxf3
with this move, black apparaently wins back the pawn immediately AND wins an exchange,but...

showcases the vulnerability of the black king

this position had been reached a couple of times OTB and in correspondence when I played the game. They all continued with 24.Bxd5. So my next move was a novelty

24.e6!N Tb7
forced move, and comes with a nice threat on b2. So obviously my move 24.e6 was backed up by computer analysis, because now comes the crazy looking

[25.Lb3? Df6= ]

25...Lxb2+ 26.Kb1 Lf6+ 27.Lb3 De8
time to evaluate. Black has an extra pawn. As compensation white has the more active rooks and, most importantly, the more active queen. King safety is a problem for both sides

28.Dg3 Kg7
[28...Lxe7?? 29.Dc3! ]

29.Th3 Txe7
[again, black cannot leave the long diagonal 29...Lxe7 30.Ld4+ Lf6 31.Dh4! ]

30.Lxe7 Dxe7 31.Tg1 De8 32.Th5
threatening Rxf5

32...Td8 33.Txf5
white has only R for B+P and now the bishop helps defending g6

only problem for black is that the bishop is soon pinned to the queen after

34.Txf6! Kxf6 35.Df4+ Kg7 36.Te1 Lxc2+ 37.Kxc2 Dxe1 38.Dc7+ Kh6 39.Dxd8
after a series of forced moves it has boiled down to this endgame which is easily won if white can get the queens off the board. In fact, black cannot really avoid a queen exchange

39...Kh5 40.Dd1+
the game is resignable for black, but he did play on for a few moves

40...Dxd1+ 41.Kxd1 Kg4 42.Ke2 Kf4 43.Kd3 g5 44.Kd4 g4 45.La4
I can always give my bishop for his g-pawn and his king qill be too far away to lock me up in the a file when I take his a-pawn 1-0
