(;GM[1]FF[4]CA[UTF-8]AP[CGoban:3]ST[2] RU[AGA]SZ[19]KM[7.50] PW[dhu]PB[alex rix]C[W+10.5 highlights: move 20 to 55 a very successful alphago inspired reduction of B's moyo that brought the game almost to endgame. There were lots of interesting possibilities here I told alex after the game it was "the most interesting variation I've played this week" 68: how to play solid locally 84: my big judgement mistake in endgame 119: nice move to make centre points for B, but there was a very scary cut that took me half an hour to read fully despite the help of playing out variations on my computer screen.

Normally with this sort of shape, B should treat G15 as a good exchange and tenuki, but perhaps W isn't too unhappy to protect at G16 in this situation, as the group reduces the B moyo nicely somewhat inspired by alphago: just a proper retreat is fine after an attachment, only hane once they've invested 2 stones leelabot is indecisive between this and G14, but eventually prefers G14 by 55 to 53% after very large playouts.] (;B[gf]C[very bad shape] (;W[gg]C[hane at head of two stones is even worse for B as E15 is at a shape point] (;B[hg]C[wow! but probably the only move this cut remains very powerful as both sides of W are quite heavy and huge.
