In this game I checkmated International Master Michael Hennigan who was the World under 18 Champion in 1988 and British Champion in 1993. He played the Alekhine defense. I got a small advantage. My e5 pawn blocked his position. I got the bishop pairs. then we exchanged pawns which helped my bishops. I started to attack his king with the bishops and the queen and he made a bad blockade which I could eliminate and I checkmated him.
