I played another blitz game (I should really give up blitz games, they're bad for my play) on FICS. This one involved a Ruy Lopez: Deferred Stenitz Var.
I am White and it is Black's turn. Can Black play 1....Bxe4?
Highlight the answer below (within the backets):
[No. 1... Bxe4 runs into the nasty Rook pin with Re1 followed by f3, winning the Bishop. Black might achieve some counterplay because of the open a7-e1 diagonal to the White King but it's still very much in the early stage and it is doubtful Black has sufficient compensation for a lost Bishop.]
