Sergash: Ireneusz Lada was born in Polland in 1948, so he was 52 or 53 years old at the time of this game, while Carlsen was 10. Lada never obtained any specific FIDE title (a Candidate Master maybe?). Rated 2205 at the time of the present game, early 2016 he is rated 1828, but his peak was 2265 in January 1995.
Chess-DB.com reports he started 97% of his known games with 1.c4... like in the actual encounter!
I checked this game with the program Komodo 10 - 64 bits.
<6.g3> Earlier that year, Carlsen had to face 6.e4 and had lost - see J Banas vs Carlsen, 2001
The theoritical novelty of the game was brought by Carlsen <11...Nd7N>. Until then, everyone (11 games in my database) had played 11...Qd7 12.Re1 Nd4 13.Ncd5 Nf5 14.Qb3 Nxe3 15.Nxe3 Rc7 = Viatcheslav Osnos vs. Efim Geller, 31st USSR Championship 1963 in Leningrad, round 8, 0-1.
<12.Ned5?!> Since the actual game, the most played move has become 12.b3 Nc5 13.Ned5 Bd7 = / A. Yanes Canizares (2280) vs. P. Aderito (2333), 48th Capablanca Open (Cuba) 2013, round 5, 1-0.
<12...Na5?! 13.b3 > 12...Bxd5! 13.cxd5 (or 13.Nxd5 Bxb2! 14.Rb1 Bg7 15.Rxb7 e6 16.Ne3 d6 = / ) Na5 = planning Nc4.
<14.Nxd5!? Bxa1> A very interesting move! Objectively speaking, it is probable, though, that 14.Bxd5 is better.
<16...Nc6?! 17.Bh6! > After this, White is threatening Qg7#. Carlsen should have played 16...e6! 17.Nc3! Nc5 or 17...Qe7
<19.Rd1?! Rb8 > The only way to maintain the same level of advantage was 19.g4! planning for g5.
