#1. Use basic strategies to get a working board and apply bi-location tool.
#2. Choose cell J6{235} - bi-location for 2 and 5.Need to form,set J6E4D6C9,progressively,a 4-element bi-location cell set.Forcing the various 1-cell to 4-cell, gives contradictions and inconclusions ;only use basic strategies and force only the 1-cell to 4-cell inconclusive values until J6E4D6C9 = (2,4,3,1) which gives the solution. Bi-location set J6H4D6C9 = (2,8,3,1) also gives the same solution.
#3. Using this solution,with basic strategies, a bi-location 3-cell set:
C9D6J2 = (1,3,3) gave the same solution. No 1-cell or 2-cell solutions were found.

Exocet : Base Cells (1579)AC2, Target Cells H1.F3, (1579)RowsBFH :
AC2=ab -> H1.F3=ab :=> -3H1, -4F3;
a=1 or 7 -> H1=1 or 7 respectively :=> AC2<>17;
AC2=1a or AC2=7a -> contradiction(Singles);
AC2=59 -> solution via XYWing(238)H4,J68-(8=5)H8.
