This is the game I playd against a much higher rated player (around more than 600 points). It is an interesting game played at my local club- and had it not been the #%(&@&*@!$ clock, I might have had a chance to win! (I must have a natural talent for losing on time - this is definately not the first time this has happened!) 

I was playing white by the way...

First, why were playing on the clock? Was it mandatory? The reason is when your placed on a clock like in tournaments and people are not use to the clocks they feel overwhelmed and tend to rush through their game. It took me a long time to adjust to a clock, but if I can finish a game without one, I'm all for it.

Looking back at your game, a few minor mistakes, but all-in-all a well-played game that you have shown here today.

What did you play after the final position?  37. Nh7 looks very strong (a couple of variations in the move list):

37.Nh7, I think Rf5 would be better than Rd8, when the rooks threatens both Rf1# and stop the white rook from getting behind the dangerous passed pawn. 

For some time, after the final position, I just moved my rook and back and forth for a while.

This was an OTB tournament game, so the clock was mandatory (dang it!). I realize that the clock is not the only reason why I lost (as Catalyst pointed out), but very unfortunately, I am not special enough to play without a clock when everyone else in the room is playing with one : )!

Hi :) Peng who was the opponent? Charles Zworestine? And was this at the St George Club Championships?
