My old WWII Navy neighbor/journeyman bricklayer (R.I.P.) told me his old tile laying trick (about thirty years ago) was to [1] mix in a bonding/flexing agent (a la previous mentions above) with the thinset, and that the best mix in is diluted* aliphatic resin wood glue, and [2] clean the back of the tile really well with acetone, then [3] after the acetone evaporates, lightly spray the back of the tile with a watered down solution** of aliphatic resin wood glue in water before back buttering or placing the tile the thinset bed.
*depends on whether you're using premixed or mix it yourself thinset, but goal is to get aliphatic resin thoroughly mixed throughout the thinset.
**one quick squeeze from the glue bottle into a quart size spray bottle of water, well shaken and allowed to settle before use... solution should still be very watery, and just slightly milky.
davester's taping suggestion should be mandatory for any tile that you actually care about.
