lead h8 h10 南上不上hq?

[bgm]

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。
