Some CB and UCI engines installed in my computer say the following:
----------------------------------------------------------------
Engine Line Evaluation
---------------------------------------------------------------
Chess Tiger 14 22.Bd3 f6 23.exf6 Nxf6 - 0.32
Deep Fritz 22.Nd5 c6 23.Nf6 Bxf6 0.31

The King 3.12d 22.Nd5 c6 23.Nf6 Bxf6 - 0.48
------------------------------------------------------------
Only 30" were allowed, so -in some cases- the line could be a bit different
should the engine have more time to ponder. Yet some conclusions are in order:
-the engines who go for 22.Bd3 are painfully aware that Black is better
-among these, Fritz 5.32 give the evaluation which -in my view- is less
accurate. The Tigers are more aware of the dangers of the position, and Exchess
provides far the more accurate evaluation.
-most of the consulted engines go for 22.Nd5. Some of then think White is
better, and among these the Fritzes provide the less trustable evaluation.
Shredder is not as bad as Fritz, but it misunderstand the situation as well.
-the Juniors are, among the commercial engines, who that provide the more
objective evaluation.
- Ruffian 1.0.1 is the absolute best.
Personally, I feel that White is already in deep trouble, no matter what move
is selected. To criticize 22.Nd5 is unfair: one has to look for better moves
earlier, much earlier.
