Many post members have argued that 4.Ng5 d5 5.exd5 Na5 6.Bb5+ c6 7.dxc6 bxc6 8.Qf3 h6 is equal; actually it is +/- because White can play the maneuver Ba4/Bb3 completely shutting down the Queenside counterplay. Since here is no attack, Black is either staring at a pawn down middlegame with no compensation for the pawn or a dead lost endgame with his fatally compromised Queenside pawn structure.

 

Once I got a winning position against Houdini 3 Pro I allowed the computer to build on the advantage. At a Depth of 28, Houdini 3 Pro claims the advantage is +1.2

minus some planless play on Blacks part, this resembles Neelotpat-Romanishin, 2008.


That game involved two grandmasters playing in a serious event. I have no doubt that some of this was opening preperation. White is not winning, Black has compensation since his pieces are more active and White cannot easily create a passed pawn.

White can improve with 20.Na4! If 20...Rad8 21.Be3 c5 22.Nb6! Qf7 23.Nd5+/- Rde8 24.g3! f4 25.Bd2 Re6 26.Bc3 R8e8 27.Ra3 e4 28.dxe4 fxg3 29.Qxf7+ Kxf7 30.hxg3 Rxe4 31.Rxe4 Rxe4 32.Rb3 Bc8 33.Rb6 Bf8 34.Rc6 Re8 35.Rc7+ Kg8 & Black is driven to a passive position; it is a general rule of thumb that a Rook on the seventh is worth a pawn, so this should be a simple technical win "two" pawns up.
