Doesn't they all use Fritz nowadays, so I doupt too that he checked with Shredder. I have done this type of tests in the past and what they have shown is that if you double the thinkingtime the score goes up (you will probably find these with a search). For now, I don't have time to do this on these tests. I only run them to give me a competitor so I think a little harder to find the correct move. To quote Bent Larsen in his book of this type if a GM took the test: "They could of course have complaint about the score, and had to agree with them in a few times."
