I think Seo Bongsu is known for his fighting style, rather than aggressive style.Uberdude wrote:I think John is suggesting that early approach is about trying to look intimidating and scary, much like a tattoed pit-bull owner, and that a calmer approach is more likely to lead to improvement. Checking pro games I see Seo Bongsu was fond of that approach and he is known for his aggressive style. He got pretty far in the world and would have been the top Korean player were it not for Chon Hunhyun. I seem to recall he didn't have a pro (Japanese) teacher and was quite popular with amateurs for his brutish fighting.
To me someone who plays 'aggressively' would be a 'one trick pony' - and there is an element of criticism about it.
'Fighting' has a connotation of a much more flexible approach - including when to duck and dive, and stooping to conquer.
a mistake, But it feels like a mistake to me: I think I became stronger when I saw the logic of invading at 3-3 here, and letting Black have the framework. If White doesn't like that, playing D12 rather than E14 makes sense to me: try first to settle the group. The D5 stone does affect choices, though. 
, though. Black can't have a framework strategy if White dominates the centre. This kind of mistake is being pattern-minded: it isn't really on an axis too passive to too active.
seems OK. As Black I would be aiming at E13, to redeem my early stones. So, I don't like 
. I would be tempted by G4, and agree to fight in the top right if needed.
seems over-concentrated, and leads Black into plenty of trouble. Up to 
I would say Black has shown a lack of skill in knowing how to defend quietly. Poor shape, really. 
is on one of the key points of Black's formation, and as Black I would answer at Q14, I think. Settle one group. Black plays a "standard pattern", but the idea of standard patterns in the middlegame is basically fallacious. The L15 stone might have combined with Black at E13, but the direction is wrong.
you say is defensive, but i'd say it is (very) agressive. It is so agressive that it is even the start of white killing the large black group, isn't it?
(alternative move 1) you say l10 is defensive. But I would think that it is a 'larger' move than k2. Yet, you choose to play k2.
and 
here aim for a large-scale game. It isn't obvious that the D5 stone is well placed here. Playable for both?
can block at the other side for almost for free and it's White's scale that increases, not Black's.
