the main line.
b) I 0 'ii'a4+ is the choice for those

who don't fancy playing the gambit

be able to defend this, White has the
initiative and can keep pressing and
pressing, leaving Black with rather
dull prospects, Nenashev-Kiarenbeek,
Khania 1 993.

10 ..... d7
This has become Black's standard

way to hold the pawn. Two other tries:
a) 10 . . . 'ii'd5 doesn't have any inde­

pendent importance since after 1 1 e4,
1 1 . . . _.b5 transposes to the main line,
whereas the greedy l l . . .lt)xe4? lands
Black in trouble after 1 2 ._g4 lt)xg3

b) 10 ... h5 !? has only been tried out

find an advantage in the main line, this
seems like the way to go.

This is currently the critical move.

White enough compensation for the

l:tb8 19 i.e l b5 was good for Black in
Dearing-Pritchett, Scottish Ch (Oban)
1 996. White needs an improvement in
this line, but an obvious one doesn't
spring to mind; for example, 14 d5
0-0-0 doesn't seem to do the trick.

14 a4 0-0-0 15 'ii'e2 h5 16 h4
Now:
a) 1 6 . . . l:th6?! is both clumsy and

slow; after 1 7 l:tfe 1 l:tg6 1 8 lllfl �b7

22 'ii'xc4 'ii'a6 (Plachetka-Skrobek,
Warsaw 1 983) White should play 23
'ii'a2 with an ongoing initiative.

b) The untried 1 6 . . . l:tdg8 !? (Piies­
ter) is better, when I don't see any ob­
vious route to an advantage for White.
