+5.54?
tal seems to be crazy.
I do not undertand a reason that it is better than 23...Rxe7.
The opposite Rxe7 that brings the rook into the attack seems to me a better
move.


Here is yace's evaluation after 23...f5(p800 64 mbytes)
It can see only a small advantage for black and it searched for 45 minutes
