Ruy Lopez, did you? Ponziani is so much more fun than 20-25 moves of theory...}
Nf6 {The main move. According to my Megabase Saric had never played against
this opening in official game. But he live-witnessed Carlsen's win against Hou
Yifan in Wijk.} 4. d4 Nxe4 ({Actually, Jobava had a game in Ponziani this year
already, but opponent deviated from the main paths with} 4... d6 5. Bd3 Be7 6.

the reputation of an ultra solid weapon where White can hardly ever lose (or
win). Jobava has his own way instead of the conventional development:} (10. Be2

is bad due to the simple} 15. Nc4 {when White regains the pawn and keeps
pressure for free.}) 15. d6 $1 {[%csl Ya8,Yc8] Diagram [#] The point behind
the sacrifice. Jobava tries to seal the bishop on c8.} cxd6 ({Another way to
defend is} 15... Bxg3 $5 16. hxg3 (16. Bc4+ Kh8 17. hxg3 cxd6 18. Nf3 Ne5 19.

situation for White arose. His four pieces are free in their motion and have
the fun part beating the black king and rook.} Re8 {If Black trades his last
active piece} (22... Rf6 23. Rxf6 gxf6 {his position will get critical after
either} 24. Rd1 (24. Rf1 {is not bad neither.})) 23. Rf1 g6 24. Bd5+ {Diagram
