Chess24 Jan Gustafsson on Alpha Zero

15th HZ Open 2011 (4)

Favourite drops his first half point in HZ Open

Arkadij Naiditsch dropped his first half point and it could have been worse against Hagen Poetsch. Jan Smeets, Konstantin Landa, Evgeny Postny, Milos Pavlovic, Deepan Chakkravarthy, Twan Burg and Edwin Van Haastert lead on 4/4. Arkadij Naiditsch and Yasser Seirawan are a half point behind. Below is a rough translation of the Dutch press release.

The strong favourite GM Arkadij Naiditsch split the points against his compatriot IM Hagen Poetsch. The latter will be satisfied with this given the assessment of the final position, but halfway through the game, surely not. Hagen Poetsch took a stranglehold, but failed to push through at the crucial moment (see diagram, and variations).

Hagen Poetsch

Position after 29...Qb6

Poetsch played here 30. e6?, but had the better 30. Qxc4 instead, for example 30. ... Bxg2 + 31. Kxg2 Rd2+ 32. Kh1 Bxe7 33. Qxf7 and the threats are legion. Naiditsch managed to wriggle loose and when the smoke had cleared Naiditsch had a bishop against four pawns against him. The four pawns were rapidly removed from the board, but there was still no more than a draw for Naiditsch.

GM Jan Smeets and GM Konstantin Landa had a much easier night. They were never in trouble and so recorded their fourth wins in a row. GMs Evgeny Postny, Milos Pavlovic and Deepan Chakkravarthy and IMs Twan Burg and Edwin van Haastert joined the group with 4 points. Yesterday's losers had excellent 4th rounds. GM Vyacheslav Ikonnikov still had the greatest difficulty in beating Sven Strange but eventually his opponent cracked. GM Erwin L'Ami also gave Benjamin Go no hope and chance of a surprise. GM Yasser Seirawan built a nice position very smoothly and easily put away the Romanian Romulus-Cristian Stefan. Chess was not always so easy!
