Andrew has just knocked over another GM.
IM Andew Muir - GM Sebastian Maze (2556) Reykjavik Open 2013
This is a good exciting tussle.
The GM goes for him saccing a piece (not sure if it was forced or planned.)
followed up by an exchange sac.
Two interesting positions pop up where the GM appears (IMO) to shun a perpetual.
Of course my Forum stalker will no doubt post 'psychology' and for once
in a thousand posts he may be right.
But by whom? (answer that one Mr £5,000 brain) 😉
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.
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 & mate that never got played.
That one I'm sure about.
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.
