In my game with Conquiscador, Black is trying a Hail Mary; he is busted in the endgame and must break through in the middlegame.
Two Knights' Defense 4.Ng5 d5 5.exd5 Na5 6.Bb5ch c6 7.dxc6 bxc6 8.Qf3!

I feel that my pressure is holding you back, but I am somewhat uncomfortable and this is the first time I have played this variation so my inexperience shows. Still, I would say my position makes it difficult for white to unravel at the moment.

My Nb7, g5, and d4 moves seemed to be my inaccuracies in this variation.
Bd1 should have been met by Nc5.
The second game with Arkhein has considerable theoretical significance. Here is how the position is after a few moves. 8.Qf3 Be7 9.Be2 O-O 10.Ne4 Nd5 11.Nec3. White is prepared to meet Nb4 with Bd1 & has enough time to castle after f5. The problem facing Black is that h6 is a useful move and it is hard to see now Black gets his pawn roller going on the Kingside without this move. In a dozen games I have played Fritz 8 in this variation, the pawn roller gives good counterplay; whether it is enough for the pawn is unclear.
White anticipates the pawn roller hence Ng3 is a strategic mistake placing the Knight in front of the advancing pawns.
This is why I am a Class B postal player. I made two moves in a row for White, Qxe4/O-O; obviously White plays 4.Qxe4, not 4.O-O?? Do you want another game with the correct move order?
Super12345---I have taken the liberty of rebutting your analysis on its merits.
1)8.Qf3 Qd5 9.Be2 is correct not your 9.Qxd5 (Your Fide 2100 player is incorrect) which just pulls the Knight to the d5 square where it has access to both f4 and b4. White dares Black to push the e-pawn. Here is analysis by Fritz 8. 9.Be2 e4 10.Qg3 Bd6 (h6 11.Nh3 +/=) 11.Qh4 h6 12.d3! exd3 13.cxd3 O-O 14.Ne4 Nxe4 15.Qxe4 Rb8 16.Nc3 is one possible continuation; perhaps you can find a better choice for Black. It is usually a bad idea for White to capture a piece when it is simply replaced with another Black piece. For the same reason it is bad idea to exchange pieces if it allows Black to reduce his pawn islands from three to two thereby losing your endgame advantage,
2)I don't like 9.Bd3 any more once Arkhein showed the correct path to refute it, hence my return to the positional 9.Be2 where Arkhein and I are discussing the merits of 8.Qf3 Be7 9.Be2! unclear
3)When you gave 8...Rb8 9.Be2 h6 10.Ne4 Nxe4 (Nd5 11.d3 +/=) 11.Qxe4 +/=
4)If 8.Qf3 Qb6 9.Be2 Bd6 10.Ne4 Nxe4 11.Qxe4 +/=
All evaluations are by Fritz 8.
The purpose of this thread is to establish whether critical lines in the 8.Qf3 variation are better for White. Due to my tendency to blunder (In two of three games), any future games will follow the format of my game with Arkhein i.e. computer assisted. I will resign games in progress with the exception of Arkhein. These should be unrated games so as not to screw up the ratings of other players.

For those interested here is the 2nd and far more interesting game between Sloughter and I.
That is an interesting game!
Oh, and "Slaughter and me." Sorry, couldn't help myself.

Rather than sloughtering this thread...sloughter some opponents with the poisoned pawn variation!

My first game with Arkhein was a refutation of one of my ideas. I tried 8.Qf3 Be7 9.Nc3? Note that if 9...Bg4 10.Bxc6ch Kf8! 11.Bxa8 Bxf3 12.Bxf3 & White has enough for the Queen.
In the second game, I tried the correct idea, 9.Be2. According to Fritz 8 I have a slight advantage but he has a stronger computer!
9.Nc3 is a blunder because it wastes a critical tempo on defense and that square in needed for the King Knight. After 9...O-O, I tried 10.Be2 Nd5 11.Nh3?! The idea is to take the sting out of f5 & attempt to use the open g-file after Bxh3.This is why 9.Nc3 is bad. I can't try 11.Ne4 because of the simple f5 -/+. Now 11...Rb8 is very strong. 12.O-O (If White can't castle, he is clearly busted) 12...Nb4! I completed missed this move; I was more concerned about 12...Rb4 which I intended to meet with 13.Kh1 with complications. Now Black is better.
13.Bd1 (Forced) 13...c5! Once he played Nb4, I knew that he intended the simple c5/Nbc6. 14.a3 Nbc6 15.b4?! 0-1 Desperation. I knew that I had to fight for equality after 15.d3 so I decided to sacrifice a pawn for counterplay. It is inadequate after say 15...cxb4 16.axb4 Nxb4 & Black has all the chances. One of the problems facing White is that there in no realisitic way to avoid d3 just loosening his postion and wasting a critical tempo. In OTB it is =/+. In theory -+. In other words it is a bust of 9.Nc3.
The correct response is 9.Be2 & should be a critical test of 8...Be7.
By the way, I spent a long time looking at the main line with 9.Bxc6ch Nxc6 10.Qxc6ch Bd7 11.Qa6 trying to save a tempo on defense, but believe it or not, Black still gets a great game even though White doesn't lose the g-pawn or get his Queen trapped in the center. It would appear that Black has at least equality after 11...O-O 12.O-O After about 8 hours, Fritz 8 instead of 12.O-O plays 12.Qd3 which is just plain weird. Even though the Queens come off, Black has more than adequate pressure for the pawns, particularly when he plays the thematic h6 at some point.
My second game with Arkhein is going better; when it reaches an evalution of over 1.0, I'll publish the score of the game up to that point, or if it reaches an evaluation of less than -1.0. The same applies to my game with Conquiscador.
Thanks for your interest. May the games begin!
