Great tournament! A Master for every 4 competitors- 225ish players in total. Here are my two games so far- Michael, I dedicate Queen b8 in the second game to you;)

Round 1 I got low on time and fxg6 was bad! I think with Rf1 I might have had some chances. Second game I played very well apart from Rb1 I think. I was looking for a way to make Ncxe4 work (Ncxe4, Bxe4, Nxe4, Qxe4, d5!) but it didn't need to be prepared. Fritz says bugger the pin on the d-file and play it anyway. I am expecting a frightening strong player in round 3 at 6pm:)

Lost an interesting (drawn) endgame after playing it pretty well up until 47. b5...
b6 in the opening was pretty awful! Am still furious about it!

All in all a great experience, it's left me keen to play more chess! I played very well, well- I calculated very well and got into winning positions against most of my opponents. Unfortunately some insecurity about my positional play made me avoid some positional lines with big advantages and cost me a few points!

All in all a great experience, it's left me keen to play more chess! I played very well, well- I calculated very well and got into winning positions against most of my opponents. Unfortunately some insecurity about my positional play made me avoid some positional lines with big advantages and cost me a few points!

Hi all,

any comments would be appreciated, especially about positional aspects of the game where I felt I let myself down in a few very strong positions.

What happened after that? White's queenside pawns are all weak, black has a very nice knight and the half opened d-file. Seems a lot to play for...

In this position my knight is pinned and the best move for black is Rg8- To be honest I was still in shock at missing Bxd4- d5-d4 looks very strong positionally to me and I only chose g4 because I thought I calculated 2 winning lines after cxd4 for white.

I'd be interested to know what anyone thinks of the position after d5-d4 instead of g5-g4:)

PS- if anyone knows Tristan Stevens please tell him that a lot of people here spoke fondly of "a very strong Australian who played here last year."
PPS- I lost feebly!

In this position my knight is pinned and the best move for black is Rg8- Sure, the N is pinned against the possibility of Bf6 but white's hands are not free either. What about ...Bc8 and if Ref1 to guard the pawn then Rd5. If white plays f6 then Bf6 is off the table so ...Nxb3 and white's pawns on d3 and a4 also look like dead meat.


I'd be interested to know what anyone thinks of the position after d5-d4 instead of g5-g4:) Yes that's probably what I would have preferred.
