Well played young Andrew.

White did indeed miss Nf3+. He missed it two moves earlier.

Amin Bassem (GM )2632 - Andrew Muir (IM) 2313. White to play.

[pos]2r2r2/pp1q1pbk/2np3p/2p1pb2/8/2PPBNP1/PP1Q2BP/R4RK1 w - - 0 1[/pos]












The tacical motif is a winning pin on the Black Queen.

The bones.

[pos]8/3q3k/8/5b2/8/3P4/6B1/5RK1 w - - 0 1[/pos]












White can play Rxf5 answering ...Qxf5 with Be4.

So we go back to the original diagram.

[pos]2r2r2/pp1q1pbk/2np3p/2p1pb2/8/2PPBNP1/PP1Q2BP/R4RK1 w - - 0 1[/pos]












And we see the plan opening up infront of our eyes with 1.Nxe5 and 2.Rxf5

Perhaps (I've added 'perhaps' but after years of studying blunders and their
causes, I'm sure I'm on the right course.)
The error has slippd in because there are three ways for Black to take back on e5.
1....Nxe5, 1....Bxe6 and 1....dxe5 and had to check each one before playing 1.Nxe5
and confirming the Rxf5 trick was still on.

At the moment the square f3 is covered twice and in two of the lines.
1...exe5 and 1...Bxe5 the square f3 is not hit.
if there was only one way to take back on e5, 1...Nxe5 then the GM's warning bells
may have/would have kicked in.

(also White's mind is on Queen Winning Pins, not Queen Losing Forks.)

Here is what happened.

[pgn][FEN "2r2r2/pp1q1pbk/2np3p/2p1pb2/8/2PPBNP1/PP1Q2BP/R4RK1 w - - 0 1"]

1. Nxe5 Nxe5 2. Rxf5 {And White has won an important pawn. Black cannot capture back on f5 because of 2.Be4 end of anlysis and 1-0.} 2... Qxf5 {But Black did take back and White now realised his lemon. He played Rf1 then resigned after Qe6. He missed.} 3. Be4 Qxe4 4. dxe4 Nf3+ 5. Kg2 Nxd2 6. Bxd2 {Black is a Rook up.}[/pgn]

Can we not stop the PGN thing from kicking in till the reader is ready for it?
Also the page load up a lot quicker.

Andrew recorded a second win against a GM in today's second match. He's now sitting on 3/3 and has the black pieces tomorrow against GM Gajewski Grzegorz, rated 2644. His rating performance for 3 rounds so far is 3111!

Another good game by the younster.

IM Andew Muir - GM Sebastian Maze (2556) Reykjavik Open 2013

An entertaining and exciting clash of ideas.
The GM goes for young Andrew saccing a piece (not sure if it was forced or planned.)
followed up by an exchange sac making it a while Rook he has dropped into the pot.

Two interesting positions pop up where the GM appears (IMO) to shun a perpetual.

Psychology?

Was the GM using his title to intimidate White and refuse the draw or did White
use his lower grade as a lure?

"C'mon don't allow the perpetual...you can beat me. You are a Grandmaster"

Of course time trouble may have played it's part.

You decide. My brief notes may guide you but don't trust them.
I've messed about with the positions on Winboard.
No engine has had a peek, which is how it should be.
The players were not using engines, so why should I.
See it how you see it. Not how some toy sees it.

So I'm not 100% sure the perpetuals are there, Black can avoid them but is
material down. If there is a mate for Black, especially in the 2nd one
then I've let it slip through.
(To be honest I've no idea what is happening in that 2nd line after 45...Qxd4.
Usually if it's 'don't know' I don't even mention it.)

There is a neat White Queen sac and mate that never got played.
That one I'm sure about. It's a leaper. (it jumps out at you.)
Always easy to assess a position after mate - the game is over.
My trouble has always been assessing a position after a combo has been played.

And always 10 times easier spotting them off board with no clock ticking
and when facing a GM who has been tossing bits at you, even if it is a leaper.

(and by the time you have read this far the game will half over and you will have to re-set it.
Surely this automatic thing can be prevented from kicking off. Who is controlling this forum.
The Mod or the PGN thingy thing?)

Nxa8 Qxa8 35. Be2 {Black is forced into saccing a piece or maybe he intended to a few moves back.} 35... Nxg3 36. Kxg3 gxf4+ 37. Kxf4 Ng6+ 38. Ke3 Bh6+ 39. Kf2 e3+ 40. Kf1 Re4 41. Bf3 Qe8 {Now Black sacs the exchange to keep the position hot.} 42. Bxe4 Qxe4 43. Qg2 {Now 43..Qxd4 44.Qxg6+ Rg7! 45.Qxh6 e2+ mates White so Andrew would have to play 45.Qe6+ with very a possible perpetual (looks like it but not 100 percent sure.)} 43... Qd3+ 44. Re2 f4 45. Ra3 {Again 45...Qxd4 46.Qxg6+ looks perpetulish. (a new word). But as before Black can stop the checks, can White stop the mating threats that are appearing all over the place. This line with the pawn on f4 and weak 1st rank look better for Black. As before if White take h6 Bishop. 46.Qxg6+ Rg7 47.Qxh6 Qd1+ and mate.} 45... Qf5 46. Qg1 Kh7 47. Nc6 Nh4 48. Qh1 Qg4 49. Qe4+ Nf5 50. Raxe3 {Nice exploitation of the pin. I've a feeling now that Black will be happy to let White get a draw.} 50... Rf7 51. Rg2 Qd1+ 52. Re1 Qb3 {Black resigned a few moves later. Andrew could have posted a position in future puzzle books with a White to play mate here.} 53. Qxf5+ Rxf5 54. Re7+ Bg7 55. Rgxg7+ Kh6 56. Rh7+ Kg5 57. Reg7 {That would have crowned that one of just perfect.}[/pgn]

Hi Andy.

Don't let this minor set back bother you. We are all behind you.

"I think Geoff will find a draw - either in rook v 3 pawns..."

Geoff could not see a win, draw or anything else in a Rook ending.

Anything to do with the attacking Kings then I'm you man, all other matters,
openings, middle game plans that don't attack a King, endgames....cue Keith Ruxton.

(in my games if I cannot attack my opponents King I attack my own King.) :U

Good Luck and keep us posted.

Geoff
