When partner opens the bidding with 1-Major and Responder makes a Splinter bid then this shows our fit, values, and shortness all in one call. This gives an excellent description of our hand and allows partner to re-evaluate their hand based on their working values. In a sophisticated partnership we may choose to have multiple types of splinters, allowing us to communicate even more information to partner. Here we look at the use of Over-Splinters and see how we can use them to give partner additional information about our hand, allowing them to better judge if slam is likely to be a good contract.

Here we look at when to raise responder's suit on 3-card support.  And then what we do after that -- the trump asking bid, sometimes called Spiral. 

A Mixed Raise shows 4-card support and 7-9 HCP in a competitive auction. Let's see how to implement this very useful bid in even more bidding situations.

When partner makes a 1-level overcall it is a very wide-ranging action in terms of strength and shape – about 7 to 18 HCP and a 5+card suit. Advancer generally assumes Overcaller has at least 10 HCP, we look at Advancer’s options for bidding and what partner should expect.

When partner makes an overcall then we have a variety of ways to raise partner's suit. Let's look at our options so we are on the same page with partner in these competitive auctions.

When partner opens in 3rd or 4th seat and we have a good hand, we do not want to go jumping around to show it – partner may have no game interest for their opening bid. We want to have an effective way of describing our good hands cheaply when partner opens in 3rd or 4th seat. When partner opens 1-Major and we have a maximum passed hand with a fit, then we want to be able to show this to partner without getting too high. This is what the Drury convention accomplishes.
