It depends.  The most efficient for me was to highlight it, copy it to 
the windows clipboard and execute the following R command.
chess <- read.table(file='clipboard', header = TRUE, sep = '\t')

If you want you can then set it to use in an R post or a script:
chess2 <- dput(chess)
chess2
# You would include similar to the following in your script or email:
chess3 <-
