Where do I hit to and what shot should I play, in this situation?
They lift to the back. alongside the middle of the left hand box.
I position myself to hit the shuttle. I'm marked "m" in the picture. The shuttle isn't super deep but reasonably deep.
My partner is not very good, and stands on the "other" side of the centre line.
If I smash it, and the opponents lift it cross court, I at the back, can probably cover it(the opponents don't put me under a lot of pressure, and I am improving at the back). And my partner cannot cover a cc lift from them when they are at the front, and my partner wouldn't try to either.
There isn't any sane reason I can see for my partner standing there.
If I smash straight, then my partner will probably fail to intercept a block from the opponents.
I have been to group coaching sessions in the past, and am used to the system described on the forum in some German videos as the tunnel system. Where P stands on my side of the centre line. And can thus intercept if the opponents block my smash. I haven't had training for when a partner is on the "other" side. Though I understand the principle that they'd cover 2 or 3 corners. Though in this case my partner would only be able to cover one corner, the one to their right, as they are not as such a level to cover more than that.
If I smash and they block it, we wouldn't get much advantage and would be under pressure.
So should I smash cross court?
I have heard the idea that your partner(at the front)'s position tells you where to e.g. smash it(if you are to do a smash). But that's normally been in conjunction with the instruction that they should stand on the side where I am.
A common thing one is told when beginning badminton is some dogma about not to hit cross court. But in this case maybe smashing cross-court is better than smashing straight.
I know I could do a drop, a punch clear, a defensive clear , but if I did smash, should the smash be cross court?
If I did a drop, should the drop be cross court?
I guess I could smash or drop to the centre line. But if I wanted to vary it then would it have to be cross court?
In this game, my opponents weren't great, and my partner there that was in that game, can play at the front. and back to some extent.
I play with good players sometimes but because of Covid restrictions, the club restricted us to not mixing players between courts , and out of some bad luck the grouping worked out like that.
