Most changes to Chesthetica that result in a slightly higher 'version number' are simply to improve the interface, by the way. White is over a rook's worth in material but the precise win in this position still needs to be found. If this one is too easy or too difficult for you, try out some of the others. Solving chess puzzles like this can be good for your health as it keeps your brain active. It may even delay or prevent dementia.
