Comparative study on counter moves.

Can you show us how the mackenzie gambit starts with a chess diagram? 

Morphy Defense the Mackenzie Variation was demonstrated in 1973 in a game of Garry Kasparov vs. Shorat Muratkuliev,  1. e4 , e5  2. Nf3 , Nc6  3. Bb5 , a6 

4. Ba4 , Nf6  5. d4 , exd4  5. d4 , exd4  6. e5 , Ne4  7. 0-0 , Be7

Mackenzie Variation for black leaves lots of possibilities for control of the center.

Ok.

Lots of experienced players gain from a good gambit, giving a pawn , or more, to gain position, nothing like a good sacrifice as long as it achieves its goal. 

Interesting views, todays gm s do not have the style of the old gm s .  The games tempo and attack strategy are different.

The importance of getting a good opening can not be denied.

The Ruy Lopez opening is seen at top levels of play.

Its good to see e4 openings still popular in play at top tournaments.
