Why are there no more adjournments? I keep reading about adjournments in books, but why don't we use them anymore? They seem like cool analysis sessions.
Primarily because computers have rendered adjournments obsolete. In addition, with the advent of digital clocks with delay or increment, it is much more fair to have people play it out over the board. It is much better to have the players decide it than having a team of people helping them overnight, or nowadays, a strong computer.
