Hi there - can people give me some pointers on the following? I am learning the game and am learning to play a basic acol system. 1. We play Stayman and Jacoby transfers over an opening of 1nt, but are wondering what to do when opposition puts a bid in immediately over my 1nt opening? What is a common treatment for this - I guess you could agree that transfers are off and just bid naturally? 2. Responding with a weak 2/3 type hand. We've played a few boards recently and not known how to communicate these hands effectively when responding to partner. Say I open 1♠ and partner has 6 hearts, 6 hcps, for example. I would take a bid of 2♥ to mean 5 hearts, at least 10 hcps. A bid of 3♥ would be a jump shift and indicate a very strong hand. How can partner show this hand - should they bid this hand? We've found that the weak jump overcall works well against opps for this type ofhand, so i guess we just need ideas on how to bid weak-raises ourselves. 3. Doubling sacrifice bids. Knowing when to penalty double is a challenge for me right now. However, can one generalise that if a sacrifice bid has been tabled by opps, when they are non-vulnerable, then a penalty double is called for? Say we feel comfortable for 4♥ (have a fit, 25 hcps) and opps bid 5♦. If they make it, then we are likely getting bottom board, so doubling it won't make any difference negatively speaking. It could make a big difference positively speaking, if they go off by 2 or 3. We play match point scoring. Thanks for any advice :)
