For example, I was playing Fire Emblem on the hardest difficulty and had only two piece left to fight with. One guarding my base and one about to take down the commander, both pieces were surrounded and it was the computer's turn.
What it, do. Instead of attacking both my characters with other pieces and killing, instead claiming my base by simply moving a single piece TWO SPACES, it send it's weak commander to kill my closest piece.
It lost, like a dumbass. I was completely ready to take the defeat and it just hands me the win of a silver plater. It was like now, it should be merciful.
