I personally play the ...e5 lines against 6.Be3 and the Panno against 6.Bg5 (...e5 lines are a blunder against 6.Bg5). If White plays 7.Nge2, then typically a trade on d4 opens the B on g7. If 7.d5, then 7...Nh5 and after 8.Qd2, you can play 8...f5 or go for the Bronstein Gambit, 8...Qh4+ 9.g3 Nxg3 10.Qf2 Nxf1 11.Qxh4 Nxe3 followed by 12...Nxc4.
I prefer the latter, but have also played 8...f5.
Have been studying a little Kings Indian Defence and getting a feel for the Orthodox, Bayonet, Petrosian etc. But the Samich variation appears to be a nightmare. Can anybody advise best counterplay? Should I do E or C pawn break or Panno or something else?
