Oct-04-05  PaulLovric: no john
Oct-04-05  aw1988: John who? Nunn?
Oct-04-05  notsodeepthought: 32 ... b5! was a nice touch, preventing the white queen from entering the seventh rank with check and pushing the black king back to g8. After that, any threat of a pin with Rg1 was gone.
Mar-14-06  Dodd: I really enjoyed that game! Played it through with my husband. Yes, he could have forced mate earlier, but he never dropped a clanger as far as I can tell. I like the gutsiness he plays with, shattering his own kings wall so early on to attack his opponent. Seems to violate the "safety before all" philosophy that so many people follow - but makes for a very exciting game. I wish I played like that in my thirties, let alone eleven. :-(
Aug-02-07  astaub: It is apparently true tht Black could have forced mate by playing ...f3 on either move 27 or move 29. However, the variations are rather tricky. The Chessmaster 9000 program found this idea to be sound. I had it playing at about a 2750 level.

Here is the analysis starting with
29...f3: Now the threat is 30...Qg4+ and 31...Qg2 mate. However, White can create room for his king on the first rank by playing 30 Rc1. If Black followed the plan indicated earlier in this paragraph, White would play 31 Kf1 and 32 Ke1 and would then be able to retreat his king bishop to f1 if need be.

The way around this defensive possibility for Black is to play 30...Rf4. Now the threat is 31...Rg4+ followed by 32...Qh1 mate. Interestingly,White can not play 31 Kf1 because of 31...Qh1 mate. If now 31 Nf4 Bf4 and there is no stopping the mate threatened by 32...Qh2+ and 33...Qh1 mate. If on the other hand 31 Bd6 , then 31...Rg4+ 31 Bg3 Rg3+ 32 fg Be3+ and 33...Qg3.

Oct-04-09  LaFreak III: 28...f3 is bad
Oct-04-09  LaFreak III: 29...f3 better
Oct-04-09  RandomVisitor: 25.Be2 might be good for white.
Oct-04-09  Cercatore: 35.Rg1 was a complete disaster.
Oct-04-09  Eisenheim: what a way to tie up the position! it was helpless before 35 rg1, after all what is better at that point?

Oct-04-09  SuperPatzer77: <Cercatore: 35.Rg1 was a complete disaster>

White has no defense against the inevitable checkmate below:

35. Nf4 Bxf4+, 36. Kh1 Qg2# 0-1

35. Ng5+ Bxg5, 36. Rg1 Qh4# 0-1

<Cercatore> So that's why White has no choice: 35. Rg1 (a desperate move) Qh4# 0-1

At age of 12, Hikaru Nakamura played extremely well against Alejandro Hoffman.

Analysis by Rybka 3 : <19-ply>

<1. (1.96): 25.Be2> f3 26.Nxf3 Nxf3+ 27.Rxf3 Rxf3 28.Bxf3 Ne5 29.Be2 Re8 30.Qb3 Qc7 31.Qg3+ Bg7 32.Bh5 Rf8 33.Qe3 Ng6 34.Rc1 Qd7 35.g3 Bb2

2. (1.13): 25.e5 Nxe5 26.Ne6 Rf7 27.Re1 Nxd3 28.Qxd3 f3 29.g3 Ng6 30.Rc3 Bf8 31.Re3 Qf6 32.Rxf3 Qxf3 33.Qxf3 Rxf3 34.Rxf3 Be7 35.Rb3 Rb8 36.f4 Kf7 37.Ba3

Oct-04-09  tivrfoa: <RandomVisitor> What white should play after 29. ... Qg4+? I think that after 30. Kh1 the best for black is a draw, because if black keeps with his plan he would probably lose, eg: 30. ... Qh4+ 31. Kg1 Kf7 32. Rd1 Rg8+ 33. Kf1 f3 34. Ke1 f3 34. Ke1 Qh1+ 35. Bf1 Rg1 36. Qd3
Oct-04-09  RandomVisitor: <tivrfoa>29...Qg4+

a) 30.Kh2 Qh4+ 31.Kg1 f3 is mate in 7.

b) 30.Kh1 Qh3+ 31.Kg1 f3 32.Nf4 Bxf4 then Qg2 mate.

Oct-04-09  tivrfoa: Thanks <RandomVisitor>. I'm confused with this: 29.Kg1 -#7/7 Qg4+?= 0.00/59

Qg4+? -> bad move
0.00 -> draw

right? :/

Oct-04-09  TheaN: <tivrfoa>

That draw sign comes from the fact that a computer considers any repetition (from the first in a position and on) to be a move for a draw. It is kind of obvious, as the computer cannot take the clock or thinking moments into consideration.

So, Rybka considers 27....Qg4 28.Kh2 Qh4 29.Kg1 Qg4 as 0.00, as Qg4 and the exact same position are repeated.

Oct-05-09  WhiteRook48: Nakamura rolled Hoffman
Oct-05-09  tivrfoa: Thanks <TheaN> :)
