Recently, I got feedback from GM Lev Alburt about a critical ending in the Sicilian Defense:
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 d5 5.Bb5 dxe4 6.Nxc6 Qxd1ch 7.Qxd1 a6 8.Ba4 Bd7 9.Nc3 Bxc6 10.Bxc6ch bxc6 11.Nxe4 f5. Lev said, "I also looked at 12.Ng5 but it doesn't seem to give more than 12.Nd2."
With regard to Nd2 he agreed that best play for both sides is probably, 12.Nd2 e5 13.Re1 Bd6 14.Nc4 O-O-O 15.Bg5 Nf6 16.Ke2 Rhf8 (To avoid doubled pawns) 17.Rad1 Bc7 18.Rxd8ch Kxd8.
"I think that White is slightly better after 19.f3---say 5.5 using my system (What he uses is a ten point system with 10 being a win for White---author) Is it enough to create REAL problems for Black, I don't know."
In the system 1.d4 Nf6 2.c4 g6 3.b4 Bg7 4.Bb2...
I'm not so sure about that move-order because of 3. ... d5. It seems pretty favorable for black to play along the lines of the Gruenfeld here.
I would rather play a late d4 and move into a French with colors reversed if I am so inclined to play b4 against a KID setup. Black is more likely to play d6/e5 in that case.
I would probably play 5...d5 instead of 5...d6, but looking at the final position after 6.d4 this seems fine, black can play 6...c5 and after something like a3 then a5 (either before or after a pawn trade) and far from white having an edge again black is probably already equal (although I tend to favor black a bit but there's probably no real edge for him).
