There’s another situation. The hail mary. You don’t have enough pieces. You can cover the potential scramble, but come up short on the land battle if he doesn’t scramble. Or you can have enough to win the land battle but not cover the scramble.
So you push everything to the land, hoping he doesn’t see the scramble opportunity. If he doesn’t,you win the land battle. If he does, you feign ignorance and ask to have the move back and not lose anything.
If you can retreat the trannies and they’re unescorted, you only lose one. And some air probably in the first combat round before they can retreat. And you’ve learned a lesson.
If it’s somebody’s first time playing, obviously we should be helping them. But if you’re playing an equal, there’s really no excuse. Where do you draw the line? I’ve J3’ed Calcutta a bunch. Need to remember that destroyer block, though. If I miss it, should somebody point it out? If I attack with bombers and the only place they can land is a place where they can get all wiped out by a couple of tanks, should I point it out? If somebody leaves Denmark undefended and Germany empty with British and American transports within range, should I point it out? C’mon. If you’re gonna be a big boy you gotta play by big boy rules.
Will I drop an “um…are you sure?” in ftf? Sure. But it’s insulting if somebody’s always pointing out your mistakes. Make em. Learn from em. Have fun and move on.
