Is the Lowenthal Sicilian good or bad for black?
Yes, Löwenthal or Kalashnikov (B32)
1 e4 c5 2 Nf3 Nc6 3 d4 cxd4 4 Nxd4 e5 is a good opening.
GM Sveshnikov played it more than his own Sveshnikov or Pelikan variation (B33)
1 e4 c5 2 Nf3 Nc6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 e5 which he considered unplayable after he published his analysis.
