Taken from a recently posted game by Robert Flesher. Deep Blue, Fruit 2.2, and Shredder 9 UCI block the e pawn by playing Be4. In this position Shredder 9 UCI played 41.Bf5, freeing the e pawn to advance. We have shown that Deep Blue and Fruit 2.2 outplay todays Shredder 9 on strong hardware. After the pawn advances to e4, the game is over and Shredder 9 loses to Fruit 2.2. Below is Fruit 2.2 eval showing it avoids allowing the e pawn to advance.
