Not really. the only way to get Jammer in 3 to 2, 4 and 6 is that red absolutely forgets what he/she is doing and forgets lane control, which is totally on red's side. Atm he can't even get into 6 as he is a black-spotted jammer so, yeah. Lane 2, when h2 is moved will be owned by red, preventing that (as even a 1 stops that) and lane 4 you're still basin yourself on the 1/6 vs 5/6 probability that red will only get a 1 (not to forget that in all of those you're considering that blue is consequently getting an even number) It is as good if you count the jammers, yes, but it is not as good if you consider the freedom you've giving to blue. Not even a 1 can elp him on G3, and even on E7, even when blue moves that F7 jammer you're halving his probability of a move here (compared to C7). For blue to care about reversing jammers down to up, it has to be freer, for now its worries are up, as it has no moves. Even IF he managed to reverse, C7 is a move that can be done perfectly at a later moment, while H4-G3 (or even E7) are moves that require more timing (as they give blue less space) being better applied sooner.
