END GAME DRAW WHICH SHOULD HAVE BEEN A WIN

In the position below, Fritz is white and has just played 54.Ke2, it is now black to play. 

In the game I played Kc3, it then played Ke3, the sequence was then repeated and Fritz claimed a draw by repetition.

I was not disappointed as I genuinely thought it was a drawn position.

It is not a draw, it is a win for black but I failed to see the winning method.

Tried to post  game below which shows how the endgame should have been played but just cannot get it to post at the minute.

I just could not see that it was needful for black to move away to b1 or b2???

I wonder how many club players would have managed to find the win from the position above?

Ecc 12:12 And further, by these, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.

PROBLEMATIC OPENING FOR ME

Nf3, g3 and other such like move orders are something I have problems with.  

Fritz opened this game with 1.g3 so I was very wary what to play against it.  

Ended up with a draw eventually.

Due to having past difficulties facing such openings, I have aquired two ways of playing against them.

One defence was supplied by Nigel Davies in a black repertoire he gives. 
Due to copyright I cannot say give any details of the defensive techniques he supplies, other to say it is very playable against 1.Nf3, 1.g3 or any of the other move orders.

The second system is a good DVD by Henrik Danielsen.  
What I like about this system, is the fact it only takes 1 hour to refresh the system in your mind, if you know your next tournament opponent may play 1.Nf3 or 1.g3 or anything similar to this move order.
