Charles I'm having trouble finding examples for this. Next Black at a: what has White achieved?
Forces the ladder ? I opened these pages following a comment I have read somewhere about the v-shape of the recommended invasion points. --Dieter
- Alex Weldon: What you're thinking of is Attack and Defense - the book by Davies and Ishida, where they suggest contact on the higher stone, shoulder hit on the lower stone or low invasion as the ways to invade this formation.
- Charles You can see the first of those at attachment invasion of mixed three space extension. The shoulderhit move is there labelled a reduction play (too). On the whole it is better that SL doesn't copy books - even good ones such as Attack and Defense - the book .
HolIgor: What ladder?

The result may be not bad for white, but I don't see a ladder.
If white is strong on the right side then this is not a natural point to invade. If black is strong there white is under attack yet.
'Forces' is too strong, though: this leaves Black with bad aji, but also White has played heavily.
This usually will be a failure for White. Charles
