Project Aho Chess Pieces
Thanks again Alex. I did add the subdiv surface to the pawn, but it ends up changing the shape which then needs a lot of adjustments, such as scaling up (again) and loop cuts. If this was my only project going on, I probably would have fiddled around a little more, but time spent is a small concern right now. I think I am getting the basics down fairly well and I am feeling a little more comfortable with Blender as a tool. I started by working on your animation course but decided to try to get better at modeling first, so I stuck this course into the middle of the other one.
- The aim of the project is for students to use CAD and 3D printers to design and manufacture a chess piece, students could also work in teams to design a complete themed chess set.

I am making a chess board and have some design concerns involving glue-up. The board will be made of 2 or 2.5 inch squares. It will have a thin beaded on top frame and then a wider frame about 2 inches on all 4 sides.
Onward and upward – as they say!
In, the chess piece relative value system conventionally assigns a point value to each when assessing its relative strength in potential. These values help determine how valuable a piece is.
They play no formal role in the game but are useful to players and are also used in to help the computer evaluate positions.Calculations of the value of pieces provide only a rough idea of the state of play. The exact piece values will depend on the game situation, and can differ considerably from those given here. In some positions, a well-placed piece might be much more valuable than indicated by heuristics, while a badly placed piece may be completely trapped and, thus, almost worthless.Valuations almost always assign the value 1 point to pawns (typically as the average value of a pawn in the starting position). Computer programs often represent the values of pieces and positions in terms of 'centipawns' (cp), where 100 cp = 1 pawn, which allows strategic features of the position, worth less than a single pawn, to be evaluated without requiring fractions.said 'It is difficult to compare the relative value of different pieces, as so much depends on the peculiarities of the position.' Nevertheless, he said that bishops and knights were equal, rooks are worth a minor piece plus one or two pawns, and a queen is worth three minor pieces or two rooks (:11). Standard valuations The following table is the most common assignment of point values (:24–25), (:40), (:6), (:340), (:11).SymbolPieceValue13359These values are very reliable in endgames with a limited number of pieces.The oldest derivation of the standard values is due to the Modenese School (, and ) in the 18th century (:255) and is partially based on the earlier work of (:115–21).
The value of the is undefined as it cannot be captured, let alone traded, during the course of the game. Some computer chess programs give the king an arbitrary large value (such as 200 points or 1,000,000,000 points, for example gives 106,332 points for king versus 14,332 points for queen in centre) to indicate that the inevitable loss of the king due to checkmate trumps all other considerations (:45), as that is the easiest way to create a computer chess program due to technology limits. In the, where there is usually little danger of checkmate, the fighting value of the king is about four points (:73). In the endgame, a king is more powerful than a minor piece but less powerful than a rook. Hsk1. Also puts its value at four points (:12). The king is good at attacking and defending nearby pieces and pawns.
It is better at defending such pieces than the knight is, and it is better at attacking them than the bishop is (:13).This system has some shortcomings. Combinations of pieces do not always equal the sum of their parts; for instance, two bishops are usually worth slightly more than a bishop plus a knight, and three (nine points) are often slightly stronger than two rooks (ten points) or a queen (nine points) (:24), (:458, 582). Chess-variant theorist Betza identified the 'leveling effect', which causes reduction of the value of stronger pieces in the presence of opponent weaker pieces, due to the latter interdicting access to part of the board for the former in order to prevent the value difference from evaporating by 1-for-1 trading. This effect causes 3 queens to badly lose against 7 knights, even though the added piece values predict that the knights player is two knights short of equality. In a less exotic case it explains why trading rooks in the presence of a queen-vs-3-minors imbalance favors the queen player, as the rooks hinder the queen, but not so much the minors.The evaluation of the pieces depends on many parameters.
For example, suggests the following values in the:SymbolPieceValue1 3 1⁄ 2 3 1⁄ 2 5 1⁄ 410The is worth 7 1⁄ 2, half a pawn more than the individual values of its constituent bishops combined. The position of the pieces also makes a significant difference, e.g.
Pawns near the edges are worth less than those near the centre, pawns close to promotion are worth far more, pieces controlling the centre are worth more than average, trapped pieces (such as ) are worth less, etc.Alternative valuations Although the 1-3-3-5-9 system of point totals is the most commonly given, many other systems of valuing pieces have been proposed. Several systems give the bishop slightly more value than the knight. A bishop is usually slightly more powerful than a knight, but not always; it depends on the position (:77,80) (:7). A chess-playing program was given the value of 3 for the knight and 3.4 for the bishop (:5).Alternative systems, with pawn = 1SourceDateComment3.13.35.07.92.2 1813(rounded) pawns vary from 0.7 to 1.33.053.505.489.941817also given by Staunton in 184733510Peter Prattearly 19th century(:439)4.164.416.62512.92Stockfish2018Endgame values.
Different types of doubled pawns (from Berliner).There are different types of; see the diagram. White's doubled pawns on the b-file are the best situation in the diagram, since advancing the pawns and exchanging can get them un-doubled and mobile. The doubled b-pawn is worth 0.75 points. If the black pawn on a6 were on c6, it would not be possible to dissolve the doubled pawn, and it would be worth only 0.5 points. The doubled pawn on f2 is worth about 0.5 points.
White should not exchange a bishop and knight for a rook and pawn with 1. Nxf7?There are shortcomings of any piece valuation system. For instance, positions in which a bishop and knight can be exchanged for a rook and pawn are fairly common (see diagram). In this position, White should not do that, e.g.1. Bxf7+ Kxf7This seems like an even exchange (6 points for 6 points), but it is not because two minor pieces are better than a rook and pawn in the (:340–42).
Also notes that two bishops are almost always better than a rook and pawn (:11).In most openings, two minor pieces are better than a rook and pawn and are usually at least as good as a rook and two pawns until the position is greatly simplified (i.e. Minor pieces get into play earlier than rooks and they coordinate better, especially when there are many pieces and pawns on the board.
Rooks are usually later and are often blocked by pawns until later in the game (:102). Three minor pieces are better than a queenThis situation in this position is not very common, but White has exchanged a queen and a pawn (10 points) for three minor pieces (9 points). Three minor pieces are usually better than a queen because of their greater mobility, and the extra pawn is not important enough to change the situation (:340–41). Three minor pieces are almost as strong as two rooks (:11).Two minor pieces plus two pawns are almost always as good as a queen. Two rooks are better than a queen and pawn (:13–14).Many of the systems have a 2-point difference between the rook and a, but most put that difference at about 1 1⁄ 2 points, see.In open positions, a rook plus a is stronger than two rooks plus a knight (:79).
pawn 2 at the start, 3 3⁄ 4 in the endgame; knight 9 1⁄ 4; bishop 9 3⁄ 4; rook 15; queen 23 3⁄ 4; king as attacking piece (in the endgame) 6 1⁄ 2; these values are divided by 3 and rounded.In the 1817 edition of Studies of Chess, the editor (Peter Pratt) gave the same values. In The Chess-Player's Handbook and a later book gave these values without explaining how they were obtained. He notes that piece values are dependent on the position and the phase of the game (the queen typically less valuable toward the endgame) (, 34) (, 30–31). gives exact values for pawns, knights, bishops, rooks, and queens as 128, 782, 830, 1289, and 2529 in the opening and 213, 865, 918, 1378, and 2687 in the endgame. The opening is defined as when the combined opening values of all pieces on the board except for pawns and kings (non-pawn material) is less than 15258 and the endgame is when the non-pawn material is greater than 3915.
