A Wonderfully Crazy Game

Transcription

1 ACN Summer of 14 A Wonderfully Crazy Game Several Arkansas players participated in the recent Oklahoma Championship in Stillwater. The last round featured a wild game enjoyed immensely by the many spectators. It was between Arkansas rising young player Alex Wolf and young star Kiana Hajiarbabi of Oklahoma via Iran. It started out calm enough, with the ultra solid fianchetto Vienna Game. Alex built up a nice position with a coming pawn storm attack on Kiana s king. But Alex got a little careless, and Kiana obtained queenside counterplay. Then things got amazingly complicated, just as (wouldn t you know) both players were falling into time trouble. The dozens of spectators were treated to an exiting performance! Thanks to Alex for sending me this game. (Annotated game next page.)

What is stronger-the central pawns supported by a ^^, or the potentially dangerous duo a+b? White's nearest task is to set his e-pawn in motion without allowing Black a timely blockade by e5. 15 re1 ne4!? Sometimes it takes a long time to realize the simplest things. It's a good idea to prevent e4 literally manually! Krasenkov's following play is a model of central restrainment strategy. 16 nd2!? Black's Ne4 is so unpleasant White doesn't shy away from further exchanges to get rid of it. Another about equivalent possibility is (16 c5 bc6 17 bc2 qc7 18 ba4 rfc8 = Compared to 15...Re8 Black has saved a tempo and he has no problems.
