Consider the suit only. If partner

- Underlead from A: play Q
- Lead singleton/doubleton: almost break even, just some minor blockage/entry problem
- Lead from small tripleton, i.e. 982: do not play Q.


So the fist question is: do partner lead 8 from 982?

What is the chance/tendancy that partner underlead from Ace?

同伴没有攻,说明不是AK打头,他也不太像同时持有KQ,否则有可能攻K。西在东技术性加倍后跳叫3,非常像有CK,那同伴的点力在哪里?这样他就非常像拿着HA低引了,所以这牌建议上Q。
退一万步讲,如果同伴单张或者双张,上不上Q没啥区别,几乎没什么损失。
