| Our goal threat is much too slow for Bomb to be useful yet. Just for grins I let Bomb think about 29b dg5s dg4s Cg2w dg3s overnight. At a depth of 18 steps (and almost all intermediate depths), it prefers 30w Ed4e Ee4e Ef4e Eg4s. It's last evaluation was -0.31, i.e. having our rabbit framed and our dog hostage makes Bomb think it has nearly neutralized our extra rabbit. Bomb would expect us to reply with 30b hd6s hd5w hc5s ed3e, which I agree is basically forced. So after 29b dg5s dg4s Cg2w dg3s 30w Ed4e Ee4e Ef4e Eg4s 30b hd6s hd5w hc5s ed3e I let Bomb think to a depth of 12 steps, and it thought 31w Ha4e Rc1e Rb1e De2w would leave it at a score of only -0.10. This just show's Bomb's helpless strategic evaluation; it would even allow us to occupy d3 with our dog! As with almost every time I dust off Bomb, I wonder why I did so instead of using the time for serious analysis, but I guess the occasional nugget of useful information is worth something.

| Thanks for the effort. I think that we are heading into waters where soon (somewhere in the end of next 20 moves ) bomb`s analysis will be useful.

The winner, not surprisingly, is dg5s dg4s Cg2w dg3s. We are now attacking f3.

For the record: . . . . . . . . . 1. 2. 3. 4. 5. 6. 7. 8. 9. 1. dg5s dg4s Cg2w dg3s (d->g2, C->f2) . . - 7 8 7 8 7 8 9 9 2. hd6w hc6s rb8s rb7s (h->c5, r->b6) . . 2 - 3 3 4 3 6 5 6 3. hd6w hc6s hc5s dd7s (h->c4, d->d6) . . 1 2 - 3 3 5 4 4 5 4. dg5s dg4s Cg2e dg3s (d->g2, C->h2) . . 1 3 3 - 5 2 5 5 5 5. dg5s dg4s dg3e Cg2n (d->h3, C->g3) . . 0 2 3 0 - 2 5 4 4 6. hd6w hc6w hb6s hb5s (h->b4) . . . 1 3 1 3 3 - 4 3 4 7. hd6w hc6w ce7s dd7s (h->b6, d->d6, c->e6) 0 1 3 2 2 3 - 4 2 8. hd6w hc6s dg5s dg4s (h->c5, d->g3) . . 0 2 3 2 2 4 3 - 4 9. dg5s dg4s dg3e dh3s (d->h2) . . . 0 0 1 1 2 2 3 2 - It is nice to have the ties and circular preferences at the bottom of the ballot this time. This week I fell way behind on my postal mixer games too, so I never looked as closely at this move as I would have liked. I'm really hoping that chessandgo overlooks the indirect threat to c2 and blunders strategically, because if he moves correctly, the tension jumps right back into the position and we have to play super-accurately to avoid falling into outright disadvantage.
