If you have ftrs, build and put on worm holes
to supplement your mines. Also if you have the tech, build Ship with ship yard tech, build 3-4 small BS on worm hole with the ftrs and mines. I found this to be effective
but if he has lots of mine sweeping, you need the ftrs and BS's, the mines won't do you any good. You might even put a small defensive fleet at the same worm hole. Use ftrs in Groups with each different type. Example, 15 with beam weapon, 15 with torp's
for total of group of 30 or more, that way you have a 1-2 punch every other turn and 1 punch each turn with each group.

just some ideas mac
