Sure, but losing the opening advantage as Black of course is not that big of a problem.
Of course. I still find the Black position rather unattractive after 8.d4 in the Bird situation, but admit that may be more of a personal taste than an objective assessment.
Quote:It is a bit ironic that the idea I found the most attractive until now reflects BirdBrain's thoughts: 7.c3 Qd6 8.Na3 intending to meet ...e5 with fxe5 and Bf4. The knight goes to c2 to protect the weak square on e3.

Further irony: that is also Vigus' recommendation. He gives the following sample line:
1.f4 d5 2.Nf3 Nf6 3.g3 g6 4.Bg2 Bg7 5.O-O O-O 6.d3 Nc6 7.c3 Qd6 8.Na3 Bg4 9.Kh1 Rad8 10.h3 Bxf3 11.Rxf3 e5 12.fxe5 Nxe5 13.Rf2
Quote:1.f4 d5 2.b3 Nf6 3.Bb2 c6 4.Nf3 Bg4 5.e3 of course still is a game - but also a game that did not serve the white side very well in the past. The horrendous score of 39% for White indicates that it demands a closer look if one is going to play 1.f4.
As a general remark, I often find that Black scores considerably better in the reversed colour situation. A tip for Bird players: study the strategies and ideas employed by strong players of the Dutch when confronting anti-Dutch lines.
In this particular line: I suppose Black's idea is to prepare for ...e5 with Nbd7/Qc7/Bxf3 or Nbd7/e6/Bd6/Bxf3. It looks advisable for White to play d4 when ...e5 can no longer be prevented. That Stonewall should offer some chances, since White has the bishop pair and good control of e4. But.... I found quite a few games where White castles short, Black castles long and then proceeds to batter White's kingside with ...g5. The lesson seems to be that White should not commit to castling too early.
