During your school days, did you ever "cut a caper" like the kids above are doing? They seem to really be enjoying their dance class.
This week continues our equally enjoyable checker series, Capers on the Kelso, taken from Willie Ryan's famous Tricks Traps & Shots of the Checkerboard. We're deep into a variation off the main line in which Willie has highlighted an interesting problem-like position.
The uncommented run-up follows below. For complete notes, see the previous columns in this series.
