The graph, with: "Upper" (highest preforming tip angle in the set), "Average" (average tip angle in the set) and "lower" (the lowest tip angle in the set) is a summary of the set. If you tip further than the 50 degrees it will fall on its side. If that piece is tipped to less than 50 degrees and let go, it will fall back to its upright position. Assuming I have given a piece an angle of 50 degrees. I measure how far a piece can tip before it looses its balance and falls over.Įg. Here, some popular plastic sets, including Shelby Lorhman's Ultimate Chess Pieces (v3). Obviously, one of the lines should be a line that represents the piece being measured and the other line should be either a horizontal or vertical reference line. It would be helpful if you would show a diagram which indicates the two lines which define the angle measured at the instant of tipping AND ALSO shows their geometric relationship to the actual piece being measured. Obviously the angle is measured between two lines. The tip data is essentially meaningless unless you show how the tip angle is defined (i.e., measured). If you think I missed an important plastic set, let me know. If you have some insight on how set claim they comply when they dont (maybe I'm interpreting the standard wrong) I'd be interested to hear from you.įor reference the allowable measurements and ratios are as follows. Though being a scaled from the FIDE world championship set, I still judged it on the ratios. NOTE: I'm giving the would chess starter set a pass on the height, as it's stated that it's not full height. The cells in Red highlight the non-compliance. Despite clams to the contrary, none of the sets fully comply with the standards. I've looked at the main ones (FIDE and USCF). So I'm guessing that is just marketing taking some liberties. I havent seen any standards for single, double, triple and quad weighting in chess pieces. The best chess set is considered quad weighted, while the ultimate is only triple. Interestingly, despite the ultimate chess set being more weighty. I'd put it as the winner in this category Not only was the tip angle on the ultimate set the best, it was also very consistent between all the pieces. So to make the comparison reasonably repeatable, I made a jig to tip the piece and help measure the angle. I understand there are some reasonably well-used sets in the market.įinding the angle that each pieces topples is not simple. I found it pretty interesting, so I thought i'd share here. ![]() This is not a review, just a comparison of some measurable metrics, and a few observations. I've done a comparison of 3 plastic chess sets.
