Subject: Junior 9 (important endgame weakness)

Author: Kurt Utzinger

Junior9 is a very fine program. One of its main weaknesses
is however the inability to evaluate correctly pawn endings
when the opposing program has a passed pawn or can create
a passed pawn. Below some examples.

White blundered with 25.Rd1?? Rxd1 with a won pawn ending for Black
