Yeah, This 23. g3 looks crazy to me also.

[Dr.Wael Deeb]

I am already waiting for the tiebreaks

[AdminX]

I am already waiting for the tiebreaks

Agreed !!!

[VP]

Yeah, This 23. g3 looks crazy to me also.

g3 is to protect the King, as the back rank is VERY weak.
Esp with the bishop also covering f1.
I think Anand is playing a good positional game...

Wow! I hope this is not a long term weakening of the white kingside.

[VP]

g3 is played as well
With this more, Topa has effectively solved many a problems, and can concentrate on the weak pawn on c file.
However, Anand can take control of the d file.

If so, then maybe 22. Rf2 not such a good move!?

[VP]

Wow! I hope this is not a long term weakening of the white kingside.

The back rank mate threat would have given Topa headaches- also doubled rooks would have hassled the white queen.
Now it is quite safe.
Very dynamic position- but black seems to have things under control.

[VP]

Rf2 is per say not a bad move, and topa is not under any trouble.
He protects the b2 pawn indirectly, and allows his queen to move...
