Returning to this:

1 e4 e5 2 f4 exf4 3 Nf3 h5 4 Bc4 h4 5 Nc3 d6 6 d4 g5 7 e5 Bh6 8 0-0 h3!? 9 g3 Nc6 (Fournier)

again... There have been some recent developments in the theory/analysis:

[Event "ChessWorld.net"]

[Date "2015"]

[White "RickF"]

[Black "tsmenace"]

[Result "½-½"]

[ECO "C34"]

...was just about okay for Black. (And I had another game which followed the same path all the way to move 31. Presumably the players were using the same software.)

But this set-up seems now to have been refuted:

[Date "2016"]

[White "AndyAndyO"]

[Black "tsmenace"]

[Result "1-0"]

I can't find anything for Black after 10 e6!. But AndyAndy came up with another, far more natural plan for Black:

[Date "2016"]

[White "juliangon"]

[Black "AndyAndyO"]

[Result "½-½"]

The idea of 18...c6! and 22...b5!, I like very much
