for those interested in 'pawn promotion,' i would like to report that i
rec'v'd my purchase of the new renko tactical cd from chessbase called
'deadly threats.'
it contains two databases involving pawn promotion examples ( among other
themes, too).
'pawn promotion' database has about 145 examples. 'pawn promotion advanced'
has 45 more.
some of these are old pearls from troitsky but there are practical example
too, many of them.
