I've asked before, "Why aren't there more draws where no obvious mistakes were made, and the players are more or less evenly matched right up to the end?"

Is this game an example of no obvious mistakes, or am I missing something? I have not analyzed it very deeply yet.

My best guess is that Csaba did not see the |32.j18 response coming. Maybe |31.g18 32.f20 33.m21 34.l21 is better, followed by the actual 35.o17 36.p15 37.q13, and then it looks like Csaba is winning: 38.o13 39.s14 40.p11 41.q8 42.p6 43.o9.

Heh, no obvious mistakes perhaps, but mistakes all the same. Just a little Twixt joke.

Under standard Twixt rules, after 49.p20 white's crossing links could not both exist, but if white just refrains from adding the new N19/P20 link, he would still have a draw, since black's response 50.n20 adding a new N20/O18 link would require the removal of M19/O20 which would give white a win. So, black still would play 50.Q22 with a draw.

Even after 33.o19 it looks like black could have won with

34.q13 35.q14 36.p15 37.r12 38.p19 39.p17 40.n20 41.l18 42.l21.

In Alan's line, how about

31.g18 32.f20 33.m21 34.l21 35.o17 36.p16 37.q18 38.q14 39.s14 40.q10 41.t11 42.p8 and black seems to win

Sorry let me change that last variation:

31.g18 32.f20 33.m21 34.l21 35.o17 36.p16 37.q18 38.q14 39.s14 40.r11 41.t12 42.p10 and I still say black wins. I changed move 40 from q10 to r11.

I change move 40 yet again. This time I add the prophylactic moves j4 and i2:

31.g18 32.f20 33.m21 34.l21 35.o17 36.p16 37.q18 38.q14 39.s14 40.j4 41.i3 42.i2 43.h1 44.r11 45.t11 46.p10 47.p6 48.o4 and black's net looks just strong enough.
