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?)
