If it's not a tactical blunder, then Shredder thinks it can play with 3 pawns for a piece here, which it cannot. 18... g6 and 20... Rda8 are good, but (according to Junior) there's nothing wrong with alternatives, such as 18... exd4, 20... Ra3. The score is about equal. After 20... Rxb4 the score is about +1.
