Dec-29-13  WoodPushkin: Greetings:

29...Qe6? loses the game. After which Komodo simply breaks down Black's position w/ technique.

Incidentally 29...Rxh4 or 29...BxNc3 and even the exchange sac of 29...RxNc3!? hold the game for Black.

Houdini does not make the strongest moves seemingly making moves at depth <=15.

Komodo's moves are more puissant as the White knight lives up to the expression and saves the win against a perpetual check. White's holding the win albeit w/ help from Houdini...

36...Re6 was a better try as giving away the b6 pawn is simply game over by force.

Also Black's light square bishop is tied down to defense (behind the pawns and inactive) because the d5 pawn is stuck babysitting the e4 square, spelling positional bust!

Finally it's worth studying the final moves of the game as the average human would fight on and there are five moves to make before the Black queen is hung or saving herself and allowing the mate of Black king.

Feb-27-14  AndrewMD: What is the best continuation here? I guess black will play 49 ...Qc2 or ...Qd3, then 50. Qe6+.
Feb-27-14  SChesshevsky: Interesting that Houdini played 13...Bh4 overworking the Queen causing a retreat tempo loss which appears to let White advance the Kside attack which may have won the game.

<AndrewMD> I'm not sure what Black can play. White looks like he threatens Rd8+ then Qc7+ or Qh5+ depending on where the King goes eventually getting behind the King with check and getting material depending where Black's Queen goes.

If Black's Queen goes to c2 or d3, the rook is vulnerable if the Queen goes to f1 its vulnerable.

I didn't work it out but by giving check and getting behind the King it looks like White's eventually going to get something and nullify Black's threats.

  SwitchingQuylthulg: This is perhaps the most human game I've seen a strong computer play. Komodo's whole plan of castling queenside, pushing its kingside pawns and opening lines is very human, and one that Houdini seriously underestimated. And in the key phase starting with move 20 or so Komodo played several important moves Houdini didn't see coming but a good human player would at least seriously consider, culminating in 29.Qe2. It's the type of position where a centaur would outperform Houdini every time - and Komodo played like one all by itself :)

It is not the case Black could have saved himself on move 29; White was completely winning by that point.

  Zhbugnoimt: 13...h4 was to stop White from going 14.h4. The tempo loss seemed justified, as White was forced to give up his LSB.
Dec-28-14  ColdSong: Strangely weak plan by Houdini.Incidentally Komodo wins in this Petrosian Kasparov variation in a very Kasparovian style,I'd say.
