5/0 time controls.  A series of three games, all against the same opponent.  Games given in order.

Game I

Game 2

Beautifully played Game 2. Impressive indeed.

In game 1, after c6 4.d4 transposes into the Panov-Botvinnik attack. I used to use this transposition until people started playing 3...e6 and going into the Icelandic Gambit.

The final of the three games.

23. c5 in game 3 would really look like White has a dangerous pawn blob and no opened files for those Rooks.

DrSpudnik: agreed, though I'd say the same analysis holds true regardless of 23:c5 or 23: Rg3+ 24: c5.  White should be able to win the ending regardless, so long as c5 is eventually played.

Right. The Rook check, though served no purpose that I could see. It may be that the King was nudged over to the f-file at a waste of tempo. The c-pawn push gives White a solid plus, with no open lines for the Rooks and two passed pawns  that will cause trouble soon enough.
