{This week I will finish my two-part article on the Lowenthal by covering
White's more critical options (with 5.Nb5). This and last week's post presents
a repertoire for Black for the player wishing to play the Sicilian without
needing to know much theory, with an emphasis on rapid development and
solidity.} 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5 5. Nb5 {I intentionally
covered White's sidelines in a lot of depth as you're just as likely to face 5.
Nf3 as 5.Nb5 at a junior/club level. But now we get to the critical stuff!} a6
({If you also want to learn} 5... d6 {, the book 'The Complete Kalashnikov'
gives you the theoretical knowledge to play this successfully, but you need to
be rated 2000+ to have any chance of following/understanding the lines! That's
one problem with opening books - they tend to give you far more theory than
you need to know about an opening, which is where a good post or coach can
help sort out the essential lines/ideas.}) 6. Nd6+ Bxd6 7. Qxd6 Qe7 ({If you
decide to learn the main move} 7... Qf6 {too, make sure you go through
Vallejo's games in this line - he's one of the experts in this system, even
beating Kramnik with it in a rapid game.}) 8. Qxe7+ ({One point of Black's
system is that} 8. Qc7 {can be met by} d5 9. Qxe7+ Ngxe7 {, when Black is a
very useful tempo up on the game! Then} 10. exd5 Nxd5 11. c3 {(to stop ...Nd4/.
..Nb4)} Bf5 12. Nd2 O-O-O {would already favour Black.} (12... Nf4 $5 {
intending ...Nd3 or ...Bd3 also looks good.})) (8. Qd1 {and other retreats
will be covered in the next two games.}) 8... Ngxe7 {This endgame is fairly
comfortable for Black, but he should memorise the following tactical point: 9.
Nc3 d5! 10.exd5 Nb4 11.Bd3 Bf5!.} 9. Nc3 (9. c4 {stops ...d5, but Black can
then occupy the d4-outpost with} Nd4 10. Bd3 d6 {, followed by ...0-0 and ...
Nec6. Black can also play ...f5 and ...b5 to chip away at White's central
pawns.}) 9... d5 (9... Nb4 {provokes White into losing the ability to castle
after} 10. Kd1 {but this is not that important with the queens off.}) 10. Bd2 (
10. exd5 Nb4 11. Bd3 Bf5 {is already completely fine for Black. For instance,}
12. Bxf5 Nxf5 13. O-O Nxc2 14. Rb1 Rd8 {would give Black good play against
White's somewhat vulnerable d5-pawn.}) 10... Be6 (10... d4 {is interesting.})
11. O-O-O (11. exd5 Nxd5 12. Nxd5 Bxd5 13. O-O-O {gives Black the choice of
castling on either side of the board; maybe} O-O {would offer more winning
chances, intending a minority attack on the queenside to try and open up
White's king a bit.}) 11... O-O-O (11... d4 {is another good option, taking
more space in the centre.}) 12. f3 Kc7 13. b3 f6 14. exd5 Nxd5 15. Nxd5+ Rxd5 {
This is a very typical Lowenthal endgame. White can press a little bit with
his bishop pair, but Black has active pieces and no pawn weaknesses. In the
end even Carlsen couldn't squeeze a win out of this endgame. Of course if this
endgame doesn't appeal to you, you can always castle kingside or play ...d4 as
indicated earlier.} 16. Bd3 h6 17. Be4 Rd7 18. Bc3 Rhd8 19. Rxd7+ Rxd7 20. Re1

Conclusion: The Lowenthal and related lines present a solid repertoire for
Black, which despite their rarity in practice are fairly easy to play as they
are based on rapid development and the creation and maintenance of a
dark-squared centre (the e5-pawn). The reason the lines here aren't popular
amongst GMs is because White can achieve a small edge if he plays the best
move every move, but they are a good choice below that level, forcing your
opponents into positions where you are much more familiar with the positional
and tactical ideas.} 0-1 Black wins
