Im referring to move 12 and 20, where my opponent makes an ogeima (large knights move) from his 2 stones. Usually it’s just a 1 space jump or keima (small knights move) and I can’t figure out a way to punish or at least get an equal result.
I don’t think it’s an overplay. The usual move would be a one-space jump (a small knight feels a bit timid if you ask me). Having said that, I think you handled it pretty well. I’m more concerned with you not attacking white’s weak group with L11 for move 9 or 11 or 13.
Yeah, I’ve no idea about it, and I’ve never had it played against me either. Maybe someone else can help you out. Locally, I would have descended (which is sente) and jumped up similar to what you did. I’ll go ahead and add those variations to the game for good measure.
The variations sure were helpful . Yeah the descent was all I could come up with. Still kinda tough. The game was mine to lose and I was pressured to build something whereas W already had a lot in the bag and the centre was still relatively open
I think the reason this is not in any joseki book is that on a 19 x 19 board this would end up being a bad result for white, but on 13 x 13, the middle is worth less, so the influence that black builds up is harder to capitalise on, and the territory white gets is ok.
Just as on a 9 x 9 playing tengen opening is a good move but 19 x 19 tengen opening is less so.
