The Full Groucho

While preparing children for their first ever chess tournament, I stress the importance of keeping a straight face so opponents cannot read one's thoughts.

The legendary Straight Face Challenge is usually an easy victory for me. (For some reason, merely looking at my face makes people laugh.)

However, Naomi not only passed the initial test with flying colours but also survived what we call The Full Groucho without losing her composure.

Congratulations, Naomi! This was undoubtedly the best performance ever seen in the Straight Face Challenge.
