Help
I've got a rubber match this evening, which is a first for me, and I really know nothing about how the odds of bidding change from IMPs. Are there any significant differences, eg of when to bid vul vs NV games (seems like they might be closer), when to sacrifice, when to bid slam, how much to allow denomination change because of 100 honours etc?
Obviously this needs to be the kind of info one can digest from a forum in a short amount of time...

I was a host for nearly a decade at the only club in the UK where they played rubber bridge for decent stakes (as opposed to Chicago), so I can offer some guidance.
The biggest single difference is non-vulnerable versus vulnerable sacrifices. -500 to save rubber looks like a great deal until you take into account that you are still 3 to 1 against for the rubber (and even longer odds if they have a part score as well).
Game bidding should be very aggressive in general because partscores bonuses do not apply (the value of a part score is notional). Vulnerable against not you do not need to be as aggressive as you do at game all - game and partscore is an even stronger position, particularly against opponents who do not understand paragraph two. You can punt bad slams here if the match conditions dictate.
There are other minor odds differences, but they are insignificant, and try not to bend it just because you have honours.
Bidding strong hands with a partscore can be a nightmare, and I can't really help you that much in a few lines. But here is one "golden rule": raising to 3NT or 4M is NEVER a slam try - it simply means you have forgotten the score.

Some other ideas:
1) Game bidding should be aggressive when they have a part score, when it's all even see part 2
2) Getting a 60 partial is generally worth 200-300 in expected points (them competing to stop you next hand, and you getting a game)
3) Don't stretch to bid slams--it gives up on the game if it goes down
4) When you have a partial, 2S means anything
(this rule is not true, but gets some of the idea of the advantage across)
