The last post in this mini-series on the opening resulting from Black’s early Lion foray, showed White retaliating in kind in response to Black supporting the Lion with the Go-Between. The position was this:
Black’s intention in supporting the Lion with the Go-Between is to follow up with a “sacrifice” of the Dragon Horse. To this end he first plays P – 5h, Ln x 4h – 4g, then plays DH x 10+, yielding this position:
Since the Horned Falcon now threatens to “eat” the Rook on 10c without moving, White has no choice but to capture it, so taking with the Rook is clearly best. Black then captures the Rook with the Bishop. The exchange of Dragon Horse for Rook and Pawn is about even, but the promotion of the Bishop gives Black perhaps a slight edge in material. Additionally, his Lion is still supported in an attacking position. Therefore White does best to retaliate in kind, leading to this position:
Now the position is almost symmetrical, the only differences being that Black has advanced his Go-Between to support the Lion, and White has played the developing move of P – 5e, opening a diagonal. If Black were to now also open the diagonal with P – 8h, White would have a chance to make it completely symmetrical with GB – 4f, but why would he choose such a slow, non-developing move, when there is no need to protect his Lion? So I conclude that Black has wasted the advantage of the first move. Extensive experience in this position confirms that Black seems unable to get an advantage in this position.
The series will continue by examining the better alternative to GB – 9g, namely retreating the Lion to 7h.
