ForewordUON 28May – Aug 2011UON 28 was to be an entirely different UON… but UON 27 ran over the size limitin megabytes and thus was split into UON 27 and UON 28.The material in this UON27 and UON28 was written by Lev Zilbermints. Use of hisanalysis in other publications is prohibited without his prior written consent. Thefirst part of Lev’s material, chapters one through five, are presentedin UON 25 (October 2009).Lev ZilbermintsDue to other commitments I have only performed a very light edit and added diagrams, but not as manyas I would have liked to.Sincerely,Gary K.

Instead, White offers a gambit with 6 Bd3Nc6 7 00. While the Clark Gambit may transpose into the Zilbermints Gambitafter 7…Be7 8 Bg5 Nxd4 9 Kh1, independent lines are well possible.While its earliest game dates from 1992, the Clark Gambit is named after RobertClark who played two games in 1999.UON 28 May - Aug 2011 Zilbermints Gambit 39

UON 28The next three games, all with the Clark Gambit Accepted, were played between1995 – 1999. The first game shows the dangers of weak defense; the second,of White not knowing the theory; the third and last, of pausing when victory iswithin your grasp.But then again, the Clark Gambit is still in its formative stages.B3.

Another line is 11…Bf6 12 Ne4with some pressure for White. While it is far from clear that White gets enoughcompensation even in these sample lines, at least 11 Qg3 is much better thanthe text move.

Commenting on the game Leisebein-Matse Rohde, corr. 2000, Leisebein states,“9 Nxd4 Qxd4+ 10 Kh1 is perhaps weaker?” My opinion is that not enough gameshave been played with the 9 Nxd4 line.

This is because the White Bishop is on the wrong square – f4rather than g5. Black has just barely enough time – one or two extra moves –to consolidate his game.
