Regarding SZ92. Maybe this game wasn’t typical as I purchased two bombers (as I like them at 12IPC), whereas most would probably buy navy or slow movers.
I think the key to stopping the attack 92 is having enough in 92 (with scramble from Gibraltar) to discourage a direct attack by the Italians, whilst also having enough in Algeria to discourage Italy invading and giving the Luftwaffe a landing spot. Depending on how the G1 attacks play out, the UK can often achieve, but without a bid I guess it is more likely this will be a stretch.
Maybe some existing units could be moved to help the UK against I1 and G2 attacks. Possibly moving one French ship from 93 to 92 could free up a plane to reinforce Algeria, or the three French infantry in North Africa could all start in Algeria. However, there may be unintended consequences to these moves, I haven’t completely thought it through.
As the intention is to have no bid (which I like as an idea), I think the board should still allow the UK to be able to secure 92 with what it has available - if it concentrates only on this move. The alternative of retreating into the Red Sea seems to give the Axis too much of the initiative, and attacking 97 is very dicey.
