Abbreviations

Hi,

I see a lot of abbreviations on various chess sites regarding tournaments, etc, and can sometimes work out the gist of them, but can someone tell me what the abbreviations following mean please: 4SS; 40/90d5 G/20d5

Thanks!

4SS; 40/90d5 G/20d5

4 round swiss system/40 moves in 90 minutes w/ 5 sec. delay (1st time control)/ sudden death second tc (I believe) 20 minutes for all moves w/ 5 sec. delay.

Four Swiss-Style rounds(winners play winners/ Losers play losers). 

That's the first part

Yes, what GD said

Ah, thanks very much both of you! The abbreviations seem a bit confusing sometimes, to the uninitiated. Why the "G" though, for the sudden death?

Thanks!

That is not the normal way I see it--usually it would be SD 20 d5 for a 2nd, final tc, but I was assuming the author's intentions. As a lone, single tc, G 20 d5 is what I'd expect to see.

Thanks!
