Instead of 35.n15, a more crucial line is |35.g12 36.e11 37.f9 38.g5 39.g7 40.h3 41.i6 42.j4 43.s4 44.m19 45.p21 46.n16 47.o18 48.n13 49.n15 50.l12 51.j11 52.k14 53.e18 54.f16 55.j15 56.j16 57.i17 58.f20 59.g19 60.h19 61.i18 62.j18 63.d20 64.h17 65.d16 66.f13 67.e14 68.g15 69.d12 70.g11 71.c5 72.d3 73.d2 74.e5 75.b3 76.c6 77.b7 78.b8

or 59.d20 60.g18 61.d16 62.d15 63.c14 64.f13 65.d12 66.g11 67.c5 68.d3 69.d2 is the same ending.

|29.p6 was arguably more forcing, but after 30.o6 31.g12 32.e11 33.f9 34.g5 35.g7 36.h3 37.i6 38.j4 39.n5 40.r10 41.k5 42.l5 white cannot connect K5 to N5.

29.o7 was sloppy and casual - and I missed the connection to r8 in the end (thinking 34.p4 was not threatening) and was doomed. I had been thinking along these lines - 29.r6 30.r10 31.o9 32.n13 33.n15 34.m19 35.p21 36.l12 37.g12 38.k10 39.e7 40.k14 and then a battle bottom left decides things, maybe 41.j16 or something in the 41.h19 area to kick off, there are quite a few lines here...

Okay, let's look at your line.

|29.r6 (I agree this is better than P6 or O7) 30.r10 31.o9 32.n13 33.n15 34.m19 35.p21 36.l12 37.g12 38.k10 39.e7 40.g9 41.d9 42.e13 43.e11 44.k14

If 45.j16 46.k15 47.j15 48.m15 49.g19 50.g17
or 49.i18 50.g17 51.h16 52.i21 53.g19 54.f21 55.d21 56.d22 57.f20 58.h20

Do you see something better for white?

Hmm, f19 might work...

49.f19 50.h16 51.g17 52.g14 53.i16
49.f19 50.g17 51.h16 52.i16
49.f19 50.i16 51.h16 52.g17 53.f17 54.e18 55.d18

You are referring to a variation from my comment. You have to repeat the entire variation in your comment, or clicking on the moves will not work. It is also recommended that you place a vertical bar | at the start of the variation from the game. Here's the process:

Click on my comment, on move 48. The following move list is automatically generated, including the vertical bar at the start.

|29.r6 30.r10 31.o9 32.n13 33.n15 34.m19 35.p21 36.l12 37.g12 38.k10 39.e7 40.g9 41.d9 42.e13 43.e11 44.k14 45.j16 46.k15 47.j15 48.m15

Copy and paste the move list into your comment. Once you have done that, make the moves of your analysis and copy and paste them in as well.

49.f19 50.h16 51.g17 52.g14 53.i16
49.f19 50.g17 51.h16 52.i16
49.f19 50.i16 51.h16 52.g17 53.f17 54.e18 55.d18

How about 50.h20 51.d18 52.g17 53.h16 54.e16 55.g18 56.g20 57.g21 58.h22, or 51.d20 52.g17 53.h16 54.e18 55.g18 56.f21

Posted comments cannot be edited, so a recommended policy is to preview and click on your moves before posting a comment.

Heh, I forgot this is Twixt PP.

|29.r6 30.r10 31.o9 32.n13 33.n15 34.m19 35.p21 36.l12 37.g12 38.k10 39.e7 40.g9 41.d9 42.e13 43.e11 44.k14 45.j16 46.k15 47.j15 48.m15 49.f19 50.h20 51.d18 52.g17 53.h16 54.e16 55.g18 56.g20 57.g21 58.h22 59.f20 60.f23 61.d21

I will keep looking.

|29.r6 30.r10 31.o9 32.n13 33.n15 34.m19 35.p21 36.l12 37.g12 38.k10 39.e7 40.g9 41.d9 42.e13 43.e11 44.k14 45.j16 46.k15 47.j15 48.m15 49.f19

Now 50.f17 51.h18 52.i16 or 51.i17 52.h21 53.h20 54.i19 or 51.i18 52.h18

|29.r6 30.r10 31.o9 32.n13 33.n15 34.m19 35.p21 36.l12 37.g12 38.k10 39.e7 40.g9 41.d9 42.e13 43.e11 44.k14 45.j16 46.k15 47.j15 48.m15 49.f19

Now 50.f17 51.g17 and I am toast. It looks like 49.f19 wins, and your O7 was indeed the losing move!

Thanks for the tips, and yes, very annoying. Can't blame O7 entirely, still missed the R8 connection....
