Bomb declares we win in 20. It continues:
45b Cg3w eg4s rh3s rd3e
46w Ef2s Cf3x Hg5e Hh5s Hh4s
46b Hh3n eg3e rf4s dg2n |

That's the only response I could find that I was leery about. If that, too, is a forced goal, then my intuition is that we can force goal on move 47. Maybe let Bomb run for a while on this 44s to see if a better 45g pops up, and then voice vote.

I ran Clueless on the position.
It is a forced win.

Shall we tell C&G that he won't live to see 48g?

Thanx everyone for finding the flaw in my continuation. I'm also finding that 44s rf5s dg3s Ch3w rh4s is best. Here's a different response and how I'd propose to handle it.
44s rf5s dg3s Ch3w rh4s
45g rd3w rc3x Ee3w Ed3e Ra5n
45s Cg3w eg4s rh3s ce5w
46g Ee3s Ee2s Ee1e Ef1e
46s Rf2s Cf3x dg2w rf4w re4s
47g Hg5w Hf5w He5s Rf1w
47s df2w re3e rf3s rf2s
So far six mobsters (including me) in favor.

After that 45g opfor finds the following forced win:
depth 14+
time 2141
nodes 211284144
qnodes 25310732
losing_moves 2903
depth_searched 4473
score 32653
pv eg4e rh3s rf4w eh4s w Hg5n Db6e Dc6x Rd4n Rc2n Rc3x b Cg3n dg2n rh2w rg2s
log: Sending forced win move in 2141.88 seconds.
bestmove: eg4e rh3s rf4w eh4s
OpFor hasn't been able to prove the forced loss from 45g yet, but seeing as Clueless was able to I certainly support the given 44s.

UT, this famous quotation from Sienkiewicz fits the mood so well... good ol' Henryk had a way with words  .
Let's move. Onwards to victory.
P.S. Almost forgot about the most important matter -when do we start the next one? I'm quaking with impatience

I think enough TheMob has chimed in. I'm making the move.

I finally looked at the position, and I vote for jdb's move too. I totally missed the point that chessandgo's threat to capture our rabbit in c3, although strong, commits his elephant so that it can't rein in our dog and stop the goal threat. The gain of material would come at the cost of a fatal loss of time. Did Clueless suggest that move (wow!) or just verify that it was a win once it was on the board?
