I could solve this puzzle logically upto this point. I would like to know apart from intuition of using uniqueness at center, is there any other steps if others can figure out ?

There is a hard deduction on the left side. You can't get past the 113 in R8C2. If you were to go past the left of it R7C3 would be an isolated cell because of the 14 and 24. The 22 blocks passing down the bottom. This means that section of the Tapa wall must connect down the bottom of the grid.

Some statistics about CTC 2016





Who would have predicted in 2012 that I would be one of the most consistent ones in a future edition? :P I still remember the drastic ups and downs from that year. Its sad that that one mistake came because of a double click around a 1-1 corner clue, would have been nice to have perfect accuracy like deu :)
