White's advantage faded away - blitz

This is a 5-min OTB game I played. At some point I felt that I had a huge advantage in piece activity, but being in time-trouble (typical of 5-min blitz) I couldn't find the correct plan and eventually blundered.

It's also possible that I simplified too much too early, but I'll let you be the judge of that:

What would be the most accurate plan for white after 14. Rhe1 Ng6    ? 

i don't see why you didn't take the free piece after 8... Nxe4.

and personally i probably would've castled the other way.. especially with the pawn missing in the c file.. you could've also protected your g pawn instead of capturing one of his on 21.. aside from that, maybe you should've waited a bit longer before trading off all the pieces in play

It's not a "free piece", for after 9. Nxe4, 9...d5 gets the piece back, although 9. Nxe4 d5 10. Qe2 might've been a better move order.

Also possible is 9. Bxf7+ Kxf7 10. Nxe4 Re8 11. Ne5+ (or 11. Qb3+ d5 12. Ne5+ Nxe5 13. Rxe5) 11. ... Nxe5 12. dxe5 Rxe5, with interesting options but dropping a pawn.

As to the castling thing, it's absolutely debatable, but the discussion is that after 13. O-O I still have to activate both my rooks.

In the position on move 17, white does not really have weaknesses to attack (in fact, it's possible d4 could be weak) because of the blocking d7 bishop, so right now the 7th rank isn't so strong. The plan of pushing the the d pawn to open the file is one try, but for that to mean anything a rook will have to be on the d file and that means black can then challenge the e file. . Like some have mentioned, Ng5! is a better way to take advantage of your pieces, as here (this blockade with a bishop on d7 is rare though) the 7th rank just doesn't seem to be enough because of this strange blockade. That must have been annoying to play in blitz especially, not having any breakthrough which you're supposed to have!
