May-30-08  stopajk24: 33..re4 nxh5+ gxh fxe4 Rxe4
not rook takes e for Qf4 check Ke2 ro e1 losing the Queen with rook e4 check so K g1 is possible then black can come on to g4 if he can get his king out of pin
May-30-08  steros: A very interesting match played by two strong players.
May-30-08  stopajk24: yes i think black could maintain his chances with this continuation may then white would respond with Qf2 - Qxe4 and would have some attacking chances but time pressure didn't let these happen
May-30-08  percyblakeney: I'm betting on 33. ... Kg8 as the move Predo made.
May-30-08  DCP23: <steros: A very interesting match played by two strong players.>

  PhilFeeley: I thought for the longest time in this game that Predojevic was holding his own against Moro. Somehow Alexander managed to grind out a win. Well done.

  PhilFeeley: The rook maneuver 34...Re4 proved to be a disaster.

  Jimfromprovidence: 34...g5 looks like a real credible alternative to 34...Re4.

Now, after 35 hxg5 Rxg5, black has a real fighting chance.

May-30-08  twinlark: Predo's first big mistake was <30...Qd6> conceding the d pawn without compensation. The right answer (courtesy of my electric abacus), obviously one that was hard to find in the zeitnot Predo must have found himself in, was <30...Rd7> and the game is still afoot:

Now if White takes the pawn with <31.exd5>, his queen is suddenly embarrassed for flight squares and his position actually becomes lost! (Also <31.e5? Ne4+!> wins).

For example after: <31.exd5 Bxd5> if:

- <32.Qc5 b6 33.Qb5 Bc6! 34.Rxd7 Ne4+! 35.Kg1 (if <35.Bxe4> or <35.fxe4>, <35...Qxh4+> with a winning attack) 35...Bxd7 wins (if <36.Qd3 Nxc3>, or <36.Rd3 Bxb5 37.Rxd8 Rxd8 28.Bxe4 Rd2>> or

- <32.Qa7 b6!> and the Queen is cut off, eg: <33.Qa6 Be4!! 34.Rxd7 Qxd7 35.Bxe4 Qd4+> with a savage attack)

From the diagrammed position, White has two options to preserve the balance, namely <31.Rxc6> and <31.Nxh5+>.

If <31.Rxc6 bxe6>:

<32.e5!> Not <32.exd5? cxd5> followed by <33...Qb8> or <33...Qc7> gives Black a powerful initiative) regains material with some (but probably not winning) advantage. For example: <32...Rb7 (Knight moves is answered by e6+) 33.exf6+ Qxf6> and after the exchange of queens and <Bc2>, White has more pieces and Black has the protected passed d-pawn:

Engine evaluation of this is a slight advantage for White.

May-30-08  sfairat: Such terrible blunders by black...
May-30-08  twinlark: (continued)

After the second diagrammed position (previous post), White can also play <31.Nxh5+> and the game becomes tactical, although with correct play, it seems to be essentially equal:

<31.Nxh5+ gxh5 32.e5 Ne4+! (<32...Qe7 33.exf6 Qxf6 34.Qxf6+ Qxf6> and White has a slight endgame advantage because of the better pawn formation, and the more active pieces) 33.fxe4>:

1. <33...dxe4 34.Rg3+ Kf8 (<34...Kh8? 35.Qe3 Re6 36.Rxd7> with advantage) 35.Qc5+ Qe7 (35...Ree7 36.e6 Rd2+ 37.Ke3 Rxd1 38.Rg8+ Kxg8 39.Qg5+ is drawn by repetition)> and White has to find the right moves (eg: <36.Rd6>) to even maintain equality.

2. <33...Qxa4+ 34.Rg3+ Kf8 35.Qc5+ (<35.exd5 Qxd4+ 36.Rxd4 Rxe5> and Black is better) 35...Ree7 36.exd5 Qf4+ 37.Rf3 Qxe5 38.Rfd3 Qe2+ 39.Kg1 Bxd5>:

Threading through this tactical maze would have been fun, with the engine evaluating equal chances for both sides.

Moro (who was also under the pump from the clock?) didn't take full advantage of Black's concession of the d-pawn when he offered the exchange of the LSBs at move 32.

With the benefit of the engine, it seems that <32.Rc5!> gouges a winning advantage, as it picks up the a-pawn without any positional disadvantage being incurred.

You really have to wonder why Predo would go for <34...Re4>, trying to thread his way through such a tactical maze while in great time trouble.

May-30-08  sallom89: such a wild game!
