Made a faulty assumption, had to restart, but really nice break-in with the 1111 forcing behaviour of the 112.

aah got stuck on this one. I think i am missing some start here. will have to try again.

The start - the 1-1-1-1 in R7C4 forces the 1-1-2 below it to have its '2' around the 1-1-1-1-1 and so the 3-3 below the 1-1-2 can only have one of its '1's. This means R10R11C3 are shaded and their counterparts for the 3-3 clue, and I think it flows well from here.

Hah, damn, I made that deduction with that other 1111 next to the 12, but failed to see it near the 33. Weird.

Thanks Prasanna for giving the logical break. I guessed to solve this one. However after reading your comment, I could solve it fully logically :)

I thought the interaction of the left-hand pair of (1, 1, 1, 1)s via the (2, 3) was beautiful

Well I was able to solve this with no guessing but unfortunately someone stopped by when I was in the middle of it and I ended up chatting for 45 minutes with them before I got back to the puzzle! It was a great puzzle though and I'm proud that I was able to work out that 1-1-1-1 and 1-1-2 interaction that Prasanna described and didn't have to resort to any guessing. Very satisfying!
