And it seems that the variation isn't dead yet! I managed to set up the position in the online NICbase tonight, -http://www.newinchess.com/NICBase/Default.aspx?PageID=400 , good search function but I can only download one game at a time-, and Oleg Romanishin who also played this line against Beliavsky is still coming up in the search for most recent games, playing 4..Bf5. I think he will know all about which reply gives White or Black the best chances! From your database it seems that 5.h3 has at least some surprise value, but the score for White is good enough that I think 5.h3 is a reasonable alternative for 5.Bf4 or 5.Nh4. 5.h3 scores 67% for White in 23 games in your database, in the NICbase online they have only kept 15 games with it but White still scores 71.8%, 10.5-4.5! But White has more options that all seem to be at least playable. 5.Ng5 is present with 8 gamesin the NICbase, White score only 3-5 that is 37.5% In your database also 8 games so that may be the same games, White scoring 38% A very recent game from Oleg Romanishin that gives more insight into what our expert in this system plays after "mainline" 5.Bf4: [Event "Vlissingen open"] [Site ""] [Date "2005.??.??"] [Round "3"] [White "Purnama, Tirta Chandra"] [Black "Romanishin, Oleg Mikhailovich"] [Result "1/2-1/2"] [WhiteElo "2337"] [BlackElo "2570"] [NIC "OI 1.6"] [ECO "A53"] [PlyCount "120"] 1. d4 Nf6 2. c4 d6 3.
