The Checker Maven

Similar But Not Quite The Same


Click on the image for a full-size version.

Can you find a total of eight differences in the two pictures above? It's a classic sort of puzzle, and unless you're rather skilled with images, finding the last little variation is often quite a challenge.

In today's edition of Checker School, we present two "similar but not quite the same" positions. The optical differences are a little easier to find than in our teaser above, but the over-the-board solutions may prove somewhat more resistant.

In both of today's positions, shown below, White is to play and win. We'll give you a small tip: one of the positions is quite a bit easier than the other, despite similar appearances. Not much of a tip, we agree, but we are known to be notably stingy in the hint department.
