wow, nice! thanks for sharing this :-D
Legal's Mate

Long before Kermer de Legall was born, Greco analyzed this line in which Legall's Mate presents itself as an unrealized possibility, but White still gains the advantage:

Excellent Example! I have found that this move order is the most common form of the Legal's mating combination. Greco analyzed this? The h3 pawn push is necessary in case Black captures the Knight at e5, so that you can recover the piece with the Queen check at b5. Traps are best that still gain the advantage even when seen, in your example, White still wins the Center Pawn and has a stronger position.

Does anyone have an opinion on the response if black's 7th move is a g6 pawn push? I don't have any engines currently installed so I can't let one analyze this (and too lazy to search out the lesser online engines). I would guess (very much a beginner's guess) Qe2, protecting the c4 bishop, but this loses some tempo (is that the right word?).

That is all correct and true... However White still wins the Center Pawn, still has a lead in development and still has the stronger position.
First I will show you Legal's Game where he first discovered this wonderful combination. Then I will post a game I played earlier today against droidR2D2 at this Site.
It will serve you well to use this trap. It is always an impressive win when used! just Remember the combination and there will be instances on the Board to use it!
