School Mathematics : Line Graph

A line graph tells you the trend of a measured parameter over a specified time period.

 Here the parameter is rating, and the period is one month.

 It helps to maintain a statistical analysis of a desired quantity, and can be read at a glance.

 Needless to say, this is the tracking of my blitz chess rating @chess.com.


P.S. 40 percentile is really not that bad at all ....  😎

Chess blogging - Chessbase is back with a bang !

In view of my keen interest in UI for applications and websites, I feel it necessary to promote an investigation of the new play-chess interface on www.chessbase.com . * It is minimalistic * Allows you to play as Guest * Allows you to choose from different time-controls * Allows you to test your skills vis-a-vis opponents from across the globe Have a look at this interface, that is impressive from a UI developers point-of-view, and very conducive for a chess player to test his wits !  Whoa !  😇😇😇

I have played a program that reached its thought horizon and then had a bizarre response inspite of  having an advantage of one pawn♟️
