csmath: 3. ...dxe4
[Sideline in Paulsen. I think Rapport is simply afraid of testing Fabiano's preparations. Caruana has already achieved reputation of dangerous opening expert.]
[Honestly I do not understand what is Rapport trying to achieve. He is striving for a tactical game but the way he is doing that provides white with more chances than black.]
[It seems that direct move 13. ...Qh2, 14. Kd2 Qh3, 15. Qa4 leads to serious advantage for white.]
[wasting time, it is obvious that black needs to play long castling and probably try to get rid of of kingside pawn weaknesses he himself created. 14. ...h5 seems natural.]
[Covering file to prepare castling and saving bishop pair. Typical positional move in style of Caruana. Black is already strategically lost.]
[Yet another move typical of Caruana studious calculation. Now he sees opening of b-file as a tactical chance and switches his plan.]
[Loses but the only chance of playing against unsafe white king 21. ...h5, 22. b3 hxg4, 23. Rxg4! does not look much better.]
[Loses outright but 23. ...Qb5, 24. Kg1 Qxh5, 25. Qxh5 leads to a lost ending though black could try to resist for a while.]
[This lift decides the game since there is no defence from stranglehold with white bishop on c6 and various motives with white rooks and queenside pawns.]
Honestly this game looks like played between two players few master classes apart.
Fabiano demonstrates in how dangerous he can be. His play is generally very sound but when he deviates from "sound" play that is always a consequence of solid calculations.
