Clearly the blunder is 106. Re1 {(Rh1) 0.00/14 14} 106... f4 {-1.53/11 14} 107.
gxf4 {-0.77/13 31} 107... Qf5 {-4.03/10 3} 108. Ke3 {(Re3) -3.66/15 29}.
If you have played through the game (as I am certain you did) you noticed
that J6a spent only 14 secs on Re1, but even after spending 31 secs on it's
next gxf4 it saw it as being only -0.77.
The only purpose for me in playing it through besides FUN !, was to see
if there were practical chances for either side. IMHO if Akopian didn't want
to let the position open up at all it could clearly be drawn.
In the position where the blunder Re1 is played Deep Junior
prefers Rg2.

>Junior6a was not fast enough not to blunder against Fritz6a in 1 hour/game
I delibrately choose 1 hour/game as I was not sure what amount of time
had been consumed by the final position. It seemed a reasonable guess
that 1 hour remained. However with Deeps speed whatever J6 plays is most
unlikely not the same.

Even the position where the blunder occurs is difficult for white and I am
not sure at that point whether it can hold.
