  Phony Benoni: These crazily unbalanced Two Knights variations are usually a lot of fun. I played them often as Black, but could never quite get the hang of them no matter how much theoretical compensation Black was supposed to have. So I'm probably not the person who should try to analyze this mess.

Any excuse in a storm.

The pun would have been better had Black's name been "Isaiah", but the game is worth it.

Nov-02-16  ninja warrior: isai, actually pronounced "ee-sai-ee" for those wondering... incidentally, isai alvarado is one of the best smash 64 players in the world (ssb being the only game i favor over chess.) =D

  An Englishman: Good Evening: Baffling game in many respects. Why did Black play 9...Nb7 instead of the usual 9...Bc5? Why did White play 10.b4? Do feel fairly certain that 18.Qxb5 was a mistake that pretty much forced Black to develop the Bc8 to its best square.

  offramp: In fact Isai is actually pronounced "eea-Zar-eeah" but after the Zar you have to make a jump to the left.
Nov-02-16  Elrathia Kingi: While there were sub-optimal moves played by both, it seems like white had the edge up until 16.Qb3+. Had he chosen instead to immediately play g3, or to play O-O, white would have held the advantage. By missing the intermezzo 16...Nc5, white gave up the advantage based on the weak position of his king. 23.Rde1 was the fatal blunder, though: simply d3 allowed white to hold on much longer.

A somewhat interesting line goes: 23.d3. Bxd3 24. Ncb5 Bxb5 25. Nxb5 Qxb5 26.Qxb5 Rxb5, resulting in an endgame where black has 2 knights for a rook and a pawn.

  al wazir: 22. Nab5 or 23. Nab5 would have been interesting. White offers a ♘ in order to trade off some material, simplifying and relieving the pressure.

Nov-02-16  PaulMeysman: @Phony Benoni I admire your honesty. But I really want to master it once. My brother once said it was a big mistake to give up a pawn in the opening but I believe the chances are equal but I cannot prove nor did I ever manage to play it well as black. When I've put this game into Fritz. Fritz equalized with a strange move 23. d3
Nov-02-16  Smothered Mate: <Elrathia Kingi>

I don't play this opening with either side, so don't have ​
my own opinions on this, but my Stockfish says that ​ 17. Qb4 ​
keeps advantage for white of a little less than a pawn. ​
(If ​ 17. ... Nxg2+ ​ then ​ ​ ​ 18. Kd1 ​ .)

  Phony Benoni: <PaulMeysman> It can be a big mistake to give up a pawn in the opening. But it can be an equally big mistake not to give one up!

Playing a reasonable gambit should provide some sort of advantage, such as a lead in development, a weakness in the opponent's position, having their king caught in the center, etc. A sound gambit usually provides an initiative, the ability to dictate the course of play.

Many players approach gambits with the wrong attitude by focusing on getting their material back. A player with that sort of attitude should probably avoid playing gambits.

Instead, the gambit player should be focusing on using their initiative to exploit their advantages while not giving the opponent time to use theirs..

That was something I often had trouble with, deciding whether to keep attacking or "cash in" and regain materials at the cost of the initiative.

As for proving the soundness of Black's play, well, that's something else which would give me trouble. I was always an instinctive player rather than a thorough analyst. But I will say this. If White is up the exchange and two pawns and has to find a "strange" move like <23.d3> to survive, then Black's attack is probably sound.

Cranking up my own computer, it appears White may have been scared off <23.d3> by the possibility of <23...Bxd3!>

The bishop is immune, as 24.Rxd3 hangs the rook on h1 while 24.cxd3 allows 24...Qb2#. Meanwhile, Black actually has the threat of 25...Ra8 trapping White's queen. (That's what active pieces will do for you.)

My computer says the best White can do is giving away a knight on b5, when after M25...Bxd5 26.Nxb5 Qxb5 27.Qxb5 Rxb5>

We are left with an ending of R+P vs. 2Ns which is probably somewhat better for Black, but a draw wold be thelogical outcome. And the attack is over.

Now, White was a master-level player in a National Championship event; why would he play a simple blunder like 23.Re1 rather than going for this line? Probably because he was a master level player who saw the consequences of 23.d3, and wanted to do better. These unbalanced positions are hard for the defender, too.

All of which proves nothing, of course. The game still has to be played. And I'm fine with that. Even if computers do "solve" chess some day, it's not going to spoil the game for us lucky people. They won't be doing anything human grandmasters haven't done for centuries.

Besides, I know I'll never be able to remember all the analysis. And, hopefully, neither will my opponents.

Nov-03-16  PaulMeysman: @Phony Benoni You are right about the psychological and time pressure about finding it over the board while you see the time ticking away. Computers don t have these troubles but human games are the best in entertainment and feeling. Chess is also art but the computer isn t an artist.
