Well, then my 18.m15 is not strong enough. Something like 18.n17 or 18.m18 or even 18.m19 will easily do the job but opens new possibilities on the left. So, the question remains whether Florian's suggestion is really winning for white 18.n1719.f14. Similar situation was 31.e13 and seemed not to be sufficient to cover both the lower left and the upper left corners (or make the connection to n11).
9.n8 10.o10 11.m10 12.k12 and 9.n8 10.o10 11.m9 12.m7 13.p7 14.n12 look good for Black. What about 9.n8 10.o10 11.o9 12.n17?
What to play instead of 7.r11? 7.s11? 7.r10?
|21.t16
.. 22.s18 23.o18 24.q15 25.r15
.. |21.t16 22.q18 23.s18
.. 21.t16 22.s18 23.o18 24.p15 25.o14 or i missed something?
|21.n17 22.q15 23.r17 24.s18 25.f14
sould be winning for white.
