double senior exocet
6789 in c357
base set 1: r6c12 - target set 1: r4c5 & r9c7
base set 2: r4c89 - target set 2: r6c5 & r9c7
shared target cell of r9c7, therefore 9 gets locked to r6c2 and r4c89
=> -9r4c36, -9b6p45, -67r6c2, -9r6c6, -9b4p5
non-base candidates removed from remaining target cells
=> -4r4c5, -2r6c5
6 in c5 is limited to target cells or r2c5, all 6s in r2 not in the cross lines are eliminated
=> -6r2c1
some basics, including an important naked triple in b5
