Curious what is the time control for Titled Tuesday, cos a lot of the games look super low quality?

After 10 seconds googling I found https://www.chess.com/article/view/titled-tuesday which says 3 minutes + 1 second.

It is currently a new trend which I've noticed. More and more analysis and even complete books are published based on blitz games see my article https://schaken-brabo.blogspot.com/2021/09/openingsstrategie-deel-2.html


This is a bit of a bugbear of mine. When looking at annotated games, it would be really helpful to the reader if the time control was stated, and more often than not, it isn't.

The last slow game I played in the 4PA was also super low quality, on my part. Sad

I'm hoping the next one will be better, and I'm using this exercise as a spur to look into my collection of 4PA sources. So far I haven't spent a great deal of time on any of the individual games. If anything of theoretical interest crops up then that might change.

TWIC 1424 (2022.02.21)

Edited:
Forgot to summarize, white scored 2/6. In all six games TWIC mistakenly had WhiteElo equal to BlackElo, so it's hard to say why the score was like that.


I give "(N)" with the same narrow technical meaning as in the Informator series. It is not a "theoretical novelty", nor even a "new move", but a move that is new to this series.

Added references:


N.B. Some of these twic1424 games are already in database.chessbase.com.

Nevertheless this is an interesting move order for black since 8.Nf3 Nc6 9.Be3 transposes back to 9.Nf3 lines, evading the 9.Be2 wrinkle. How much of an achievement this is for black depends on who is white. Note that 8.Nf3 Nc6 9.d5? Nb4 10.Nd4? is well met by 10...Qh4+.

TWIC 1423 (2022.02.14)

New series, let's see how long / how regularly I maintain it. White scored 3.5/4, but it could have been very different.
