thickness problem  

Fernobob: I was in this position playing as black and noted that while I had fairly little territory, I had a lot of influence over the centre. I'm lead to believe that it's far better to put use influence to attack weak groups than to attempt to turn it into territory but there didn't seem to be any weak groups on the board. In the end, after a nice reduction at the top I went at a but feel that I could have put my influence to better use. Could I have?

thickness problem  

unkx80: While a is not a bad proposal, it does not put any pressure on any of the White groups. If I am to play in that direction, I will play at b to put pressure on white+circle.

However, White does have a relatively weak group on the left side, and the Black group at the top has many cutting points, so I will choose to play at B1 to strengthen it. After B1, I feel that White has no really good way of defending against the invasion at c? In any case, it seems that Black can easily seal the White group in to form a large framework.

By the way, be prepared to sacrifice the black+circle stones if White plays at d. One possible answer is simply to play elsewhere.

Fernobob: Thanks; Supposing there were actually no weak groups at all and my groups didn't have those cutting points, ho would I use influence to make territory in the long run?

unkx80: That depends on the overall position: how thick your groups are compared to your opponent's, and also where the influence is facing. However, in most cases I will be rather pessimistic if you merely have influence but all your opponent's groups are very safe.
