so your partner, who might even be a passed hand, bids a third suit.

it might go like this:

1club by opp-p-1sapde- by opp- 2 hearts by partner

or

1diamond by opp-p-2clubs by opp-p-3clubs by opp- 3 sapdes by partner

the opps then go on to bid higher, and i go out of my way to lead the suit, especially if they are in nt and our saide has a fit

usually the suit is crap, and truly i do not want to know if they have that crap headed by a jack

it is very common at bbo so i have decided that i will lead what i feel like leading

the lead directing double of a wonder suit headed by the queen is just super

for partner with whom i play again, i simply warn them, be careful what you overcall, i will lead the suit and ignore all your signals, period.

what ticks me off tho is that i dont see parameters for this in any book.

an overcall is different from a balancing call, so i will not lead a balancing suit

You should always assume that your partner has a reason for making a bid, especially if the bid is into the teeth of the opponents' auction.

Lead partner's suit (assuming that you don't have a standout lead of your own or some very good reason not to lead partner's suit - a void is a good reason). Normally, partner will have top tricks to cash or establish in his suit.

If you routinely play with partners who overcall trashy suits at high levels, then you need new partners.
