Our model takes a triplet (color, piece, square) as the input and calculates a value that measures the advantage\/disadvantage of having this piece on this square. Our methods build on recent advances in chess AI, and can accurately assess the worth of positions in a game of chess. The conventional approach assigns fixed values to pieces (= \u221e, = 9, = 5, = 3, = 3, = 1). We enhance this analysis by introducing marginal valuations. We use deep Q-learning to estimate the parameters of our model. We demonstrate our method by examining the positioning of knights and bishops, and also provide valuable insights into the valuation of pawns. Finally, we conclude by suggesting potential avenues for future research.<\/jats:p>","DOI":"10.3390\/e25101374","type":"journal-article","created":{"date-parts":[[2023,9,24]],"date-time":"2023-09-24T14:36:26Z","timestamp":1695566186000},"page":"1374","source":"Crossref","is-referenced-by-count":0,"title":["On the Value of Chess Squares"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"http:\/\/orcid.org\/0009-0009-9675-1434","authenticated-orcid":false,"given":"Aditya","family":"Gupta","sequence":"first","affiliation":[{"name":"Chess ED, 729 Colby Ct, Gurnee, IL 60031, USA"}]},{"given":"Shiva","family":"Maharaj","sequence":"additional","affiliation":[{"name":"Chess ED, 729 Colby Ct, Gurnee, IL 60031, USA"}]},{"given":"Nicholas","family":"Polson","sequence":"additional","affiliation":[{"name":"Booth School of Business, University of Chicago, Chicago, IL 60637, USA"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-6618-2965","authenticated-orcid":false,"given":"Vadim","family":"Sokolov","sequence":"additional","affiliation":[{"name":"Department of Systems Engineering and Operations Research, George Mason University, Fairfax, VA 22030, USA"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,24]]},"reference":[{"key":"ref_1","unstructured":"Turing, A.M.
