C[This is a tricky position.  If I remember right, Peter told me that Mohex reports Black  has exactly 2 winning moves here.

I know B5 wins, and I think D4 is the other one.


Mohex\: Actually, b5, f2, and e4 are winning. d4 is not.]

C[As I mentioned in the chat at the time, I had a forced win that I knew how to carry out, but I intentionally didn't play it.

(That was to give Black another chance.)]

C[F1 and F2 also win, but don't help - https\://www.hexwiki.net/index.php/Captured_cell - and this is Black's only other winning move.]
))(;B[b3]
C[D5 does still win, but foiling was more efficient and much simpler.]))
(;W[e2]
C[E2 is captured to the F-edge, so White has a ladder escape fork at B2, which means White-to-move can connect C4 to the A-edge via the A1-corner.

C4 also has a template to the F-edge, and White foils if Black intrudes into that template, so Black will get just a ladder along the 6-edge, which does not connect.]
))(;B[b5];W[b4];B[d4]
C[Black gets ladders along both of Black's edges, and due to C3 and B5, both ladders connect.]
