After some maneuvering a dynamically equal position is reached, but then Black allows White to go for a strong attack in the center and up the f-file. I have previously identified my attacking play as an area where improvement is needed, something which was reinforced by the sub-par conduct of this attack. The move f6! is available for quite some time, but is never actually executed, to White's detriment. White's attack peters out into a won endgame position where I was unable to find the key to make progress, allowing Black to sneak in a draw by repetition.
This is the first game published here using the latest Aquarium update.

is Houdini's second choice.
[Its first is 8.d5
which although it doesn't appear so at first glance, is in fact a very forcing move. The double threat of dxc6 and d6 forces Black to lose a pawn or suffer a massive positional bind. 8...exd5

the position is now equal. The doubled pawns are compensated for by the semi-open f-file and greater piece activity due to White's lead in development. As will be seen, the extra e-pawn can even be useful. 14.Kh1

done in order to get the king off the a7-g1 diagonal occupied by Black's bishop and offer a pawn sacrifice. With Black's underdeveloped position, taking the pawn on e3 would be rapidly punished. 14...d6

15.Nd5

31.f6
g6
32.Bxg6
and White has nothing to worry about.]
29...Nc6
Unfortunately Nimzovich's dictum "the threat is stronger than the execution" only goes so far. Here's where f6 should have been executed (again). Instead, the attack starts petering out. 30.Be6

White is still winning, although the double rook and minor piece endgame looks nowhere near as easy as the attack did several moves ago. 33...a4

Here the simple Rxc5 should seal the deal, with Rd5 available as a follow-up to hold the d-file. 35.Bd7

I still needed more time to find the key to the position, Bd5 not occurring to me. Unfortunately... 51.Kf4?!
