I don't play very much on KGS anymore; however, I played this game and really enjoyed it. I made a few obvious mistakes that I noticed, but I think it deserves a review. Oh unfortunately, I couldn't finish this game due to time since I had a Calc class I needed to attend.

Maybe your calc teacher can explain about 1 hour = 60 minutes and so on? I used to do so when my students arrived late.

Proverb: vital points before large points. Making a base for an unsettled group is vital, not merely large.

Up to move 25, B has a nice attack going, but W has compensating profit. B has a large investment in the three stones on the left, so it is important to keep them strong and efficient. Playing an extension to make a base for this group sometime soon (before W can counter-attack) is critical.

:b31: strikes me as an overplay. You cannot surround these W stones, much less kill them, so this seems like a good time to switch to a vital extension on the left side like C6 or D6. If W cuts at K13, you have the tesuji sequence L13-K14-K15-L14-L15 to escape.

:b35: defends the K13 cut and threatens a large hane at L16, but allows W to switch to the left side, which looks more important.

:w36: is huge, making a base for W and depriving B of a base. Vital points like this are much larger than may appear at first glance. The three B stones on the left are suddenly floating and have lost all attacking and territorial prospects.

:b39: is again big, but not as vital as :w40:. Now B will have to struggle just to live here, letting W consolidate a large corner territory in the process.

There were some mistakes in the fighting after this, but the real problem was getting into this situation in the first place.

Thanks Mitsun. Very helpful. I'll try and look out for the vital moves as opposed to the big moves.

Sure b has plenty internal threats but in the end position wF11 makes the left side ko, no?
