Our two basic games are called Tom and Jerry; the main application is the biregular construction of most of the anticanonically polarised Mori Fano 3-folds of Altinok's thesis. There are 115 cases whose numerical data (in effect, the Hilbert series) allow a Type I projection. In every case, at least one Tom and one Jerry construction works, providing at least two deformation families of quasismooth Fano 3-folds having the same numerics but different topology. © 2012 Copyright Foundation Compositio Mathematica."}],"doi":"10.1112/S0010437X11007226","author":[{"last_name":"Brown","first_name":"Gavin","full_name":"Brown, Gavin"},{"full_name":"Kerber, Michael","first_name":"Michael","orcid":"0000-0002-8030-9299","last_name":"Kerber","id":"36E4574A-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Reid","first_name":"Miles","full_name":"Reid, Miles"}],"_id":"3120","citation":{"ista":"Brown G, Kerber M, Reid M. 2012.
