Black is generally happy to play with two knights against knight and bishop  (preferably white squared).} 6. Be2 Bxf3 7. Bxf3 {The downside of this  exchange is that Black becomes completely passive since the two possible  sources of counterplay - b5 and f5 - both become almost impossible to achieve  under favourable circumstances when there is no counterpart to Bf3.} Be7 $2 ({  The principled move here is} 7... g6 $1 {intending h5 and Bf8-h6.

Firstly, it means  that Nf6-somewhere, can be met with h4, avoiding the exchange of the dark  squared bishops. Secondly, it aims to keep protecting the e4-pawn with the  bishop, in order to give the knight the freedom to find a better purpose. And,  thirdly, the bishop will eventually be very well placed on h3.} O-O (8... h5 9.  h4 $1 {and Black gets nowhere.}) 9. O-O Nbd7 10.

Black is positionally bankrupt, but maybe he can  get enough activity with Be7-d8-b6 and Nd7-c5, to compensate for everything  else?! No, not against Iturrizaga...} 13.
