TA 1999 Problem 1 / Attempts

Analysis of the corners:

Upper left: the move at Black 18 (a) is forcing but the exchange of the stone in the corner for a stone in the center is perhaps more favourable for White at this stage.

Lower left: White can live in gote, Black can kill in gote so the corner is 11 points miai counting. It is very large but there are oba still on the board.

Upper right: the region where White reigns at the moment. Requires reduction.

Lower right: Black lives small and White has some forcing moves there threatening to enclose the right side.

Center: White has a useful but weak group.

The upper side is low, so I think that the most promising plan is connected with the hasami on the right side. But the magari at 1 is too painful. I'd play 1 hoping to scare my opponent to extend. Pushing along the sixth line is a bad thing but Black has a lot of moves that would reduce White's territory at the bottom.
