White's Kt-a4 had a purpose, attack the enemy Q. Black's Kt might have been better at its usual c6.

Far ahead in material, my method now is to exchange off everything possible. As the board empties, the White Q's power will make itself felt.

The c-file just opened up! Rooks are attracted to open files like fat to a mother-in-law.
11. Na4xc5
Swap all the pieces!

Another exchange?
12... Nc5e4
Sadly no. The Kt takes up an excellent outpost at e4. It is secured by a pawn, backed up by the fellow Kt, and White's e pawn shields the Kt from frontal attack.

Had to decide between eliminating that nasty e4 Kt or getting my Q going against an uncastled King.

Has to get his c Bishop out somehow.
14. Qd1a4
The Q enters with tempo by a check. Three White pieces are aiming at the enemy K. And that c file still calls.
