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 ! 😇😇😇

Binary trees are a specific version of decision trees that have two nodes,one parent and two children, and this concept is used in database programming with relational databases like SQL server for creating in clustered and non clustered indexes. Alpha beta pruning together with B tree searches makeup the basis of chess programming. I have played a program that reached its thought horizon and then had a bizarre response inspite of having an advantage of one pawn♟️
