White will have to find an early improvement, not that I am very optimistic currently. I let Yace run on the final position for some time just to make sure, so for what it's worth: 1.Td6+ Kc7 2.Tf6 Lh1 3.Tf1 Lg2 4.Kf4 +- (1.95) Tiefe: 63/90 17:20:40 2273294kN That's definitely a draw score in this case, it had 1.95 since ply 48 and similar scores before, also your explanation is logical.
