I suspect a big catling bug by Fritz7
Fritz7a did not expect 18.0-0-0 and had evaluation of 0.00
Can Fritz7a find 18.0-0-0 in it's main line at move 17 after enough time
Not that black has no good alternative to 17...Qe5
Here is yace analysis after learning that 17...Qe5 is bad
and Deep Fritz anaysis on p800(48 mbytes hash) when it has no problem to expect
0-0-0 and see that white has a big advanatge after 17...Qe5
The problem was clearly before 17...Qe5 but it is possible that the castling bug
prevented Deep Fritz to play better in previous moves
