So Nakamura played the Leningrad Dutch in the closing round of the Tal Memorial aginst Grischuk, had a winning game, and then threw it all away and had to settle for a draw.
In the Blitz Tournaments Naka played the Bird's, Leningrad Dutch with colours reversed but was less successful.

Enter 1 f4
Bird's Opening!
By IM Andrew Martin

'Back in the late seventies and eighties it was the Trompowsky Opening (1 d4 Nf6 2 Bg5) which was giving Black a serious headache. Will 1 f4 continue in the same tradition in 2010 and beyond?'

In typically forthright style, IM Martin presents his case to try and prove that Bird's Opening is worthy of a place in an opening repertoire - albeit as an occasional weapon of surprise.

The material is split into the following segments:

Bird Game

From Gambit

Leningrad Game

Other Systems

The late Bent Larsen is prominent on this DVD, just as he is on 'Bamboozle'. Indeed, there is a little bit of a crossover with some of the given lines too, with White heading for a reversed Leningrad Dutch as part of the recommended repertoire.

I was interested in the unusual method given against Black's From Gambit. 1 f4 e5 2 fxe5 d6 3 Nf3 dxe5 4 e4 - with an unusual sort of King's Gambit Declined, with options of Bb5 and the chance to build a strong centre with c3 and d4.

Everything appears to be fairly easy to play and worth a try at a local level, but I suspect 1 f4, unlike the Trompowsky, will remain an opening with a cult following.

Note: I looked up the above mentioned From's suggestion on www.chessgames.com and came across the following: 12 games, +5, -5, =2

Four of the last five games, since 2001, were White victories, although most of the players were in the 2100 range.
