I'm black. Move 19 isn't something I would have looked at before. For me it's counterintuitive to capture a protected minor piece with my queen. I think I missed mate in one on the second to last move.
I've only been casually practicing tactics on chesstempo here and there on my iPhone. Is it worth buying a premium account on that site?
basically black stakes a claim in the centre by advancing the d pawn.... the mainline continuation is 1 b4.....e5 2 bb2 bxb4 3 bxe5 which white will know well.....
IM GARY LANE SUGGESTS THIS
the best policy is to give black immediate problems to solve in the opening by constructing a pawn centre..
black plays 1 d5 followed by moving queen out to d6 where it not only targets the b4 pawn but also supports the central advance e7-e5. The middle game plan is to develop the kingside swiftly and bolster the pawn centre. A short, sharp game will be enough to catch a glimpse of how black should handle the opening.
