Kraków Seniors Round One

Jakub Marszałek (1345) - Spanton (1743)
Vienna Game
1.Nc3 Nf6 2.e4 e5 3.a3!?
An interesting bit of tricoration. One idea is that after 3...d5 4.exd5 Nxd5 White can play 5.Qh5.
Position after 5.Qh5 - this is a Steinitz Variation of the Scotch with colours reversed and White having the extra move a3, which cuts out the response ...Nb4

3...Bc5
A more-measured response - hoping to make 3.a3!? seem irrelevant.
4.Be2 d5 5.exd5 Nxd5 6.d3 0-0
It still looks like a Reversed Scotch, but with White having played much more passively than Black normally would

7.Nf3 Nc6 8.0-0 Re8 9.Ne4 Bb6!?
Looking after the kingside with 9...Be7 or 9...Bf8!? may be better.
10.c3
Stockfish16 and Komodo14.1 give 10.c4!? Nf6 11.Bg5 with an initiative, not least thanks to the threat of 12.c5.
10...h6 11.Ng3 Be6 12.Bd2 Qf6 13.Re1 Rad8
Black has activated every piece (apart from the king), while White is still to move his queen and king's rook - nevertheless the engines reckon the position is equal

14.b4 Nf4 15.Bxf4 Qxf4 16.Qd2 Qf6 17.Ne4 Qe7 18.h3?!
Almost certainly too slow. The engines suggest something like 18.Ng3!? a6 19.Qc2 Qd7 20.a4 with more-or-less equal chances.
18...f5 19.Nc5!?
Even worse, according to the engines, is 19.Ng3 e4.
19....Bxc5 20.Bxc5 Qxc5
I have given back the bishop-pair but emerged a pawn up and with more space and the better pawn-structure

21.Qb2 b6 22.Rad1 a5 23.Rd2?!
The engines much prefer 23.d4.
23...e4 24.d4 Qd6 25.Nh2 Ne5!? 26.Red1 Nc4 27.Bxc4 Bxc4 28.Nf1 f4 29.d5?
White should have done something about Black's threatened next move.
Black to play and get a large advantage

29...e3 30.fxe3 fxe3 31.Re2
The engines agree this is best, but after ...
31...Bxe2 32.Qxe2 Qxa3
...Black is the exchange and two pawns up.
The game finished:
33.Rd3 Qc5 34.Kh2 Rxd5 35.Qa2 c6 36.Qe2? Qd6 37.Kh1 Rxd3 38.Qg4 e2 0-1
