Sergash: Pat Reynolds is an Irish player who had no FIDE rating at the time of this game (?). I could not find his birth year. Early 2016, he is rated 1937, but the highest rating he ever achieved has been 2146 in 2003. He never earned any FIDE title.Carlsen was 10 years old and rated 2084.
This game appears to have been the first time Carlsen ever played against the Trompowsky Opening.
<8.g4?!N> This was the theoritical novelty of the game, one which doesn't improve anything... Before that, there had been :
A) 8.Nd2 Nbd7 9.0-0 c5 10.c3 = Dinko Brumen (2385) vs. Joze Skok (2145), 19th Bled Open (Slovenia) 1998, round 1, 1-0
B) 8.c3 Nbd7 (8.c5 9.dxc5 Nbd7 10.b4 a5 11.Nd2
Anna Tkacheva vs. Tatiana Marinina, Under 12 Woman Russian Championship 1999, round 9, 0-1) 9.Nd2 (Hans Martin Kolb vs. Klaus Seeger (2105), Baden VLN (league) 01-02 (Germany) 2001, Untergrombach against Heideberg II, round 4, 1-0) e5!

<20...Qa4?!> Carlsen could have secured a solid advantage with 20...Qb5! 21.a4 (or 21.Nf6+ Kh8! 22.f4 d3! 23.Bb2 Rfd8 24.fxe5 Qxe5!
winning back the piece. Komodo 9.42 64 bits) Qc4 22.Nd2 Qc5! 23.Bb3 Bxd5 24.Bxd5 Nb4! 25.Rc1 Qa5! 26.Be7 Nxd5 27.exd5 Rfc8!

Apaprently, Carlsen could not see the difference between 20...Qa4?! and 20...Qb5! He had a second chance to play that line on 22...Qb5! but agreed to the draw offered by his opponent. Or maybe he was still tired of the previous day's win in 58 moves against Philipp Scheffknecht?
