If first seat opens, and you might be within the second seat, you want opening values with a purpose to make a take out double (that’s 13-14 hcps, perhaps 12 with 4-4-4-1 or 5-4-4-0 distribution, whereas quick in opener’s go well with). Even then, you concern that third seat may have an “opening” hand, that’s most or all the remaining factors, leaving your accomplice with nothing.
If you’re within the fourth seat (that’s the “balancing”) seat after and opening and two passes, you can also make a takeout double with a couple of king much less, that’s, Sep 11 excessive card factors. That is as a result of third seat has proven lower than 6 factors by passing opener’s bid. If opener has near the minimal 13, third seat has 5, you may have 9, your accomplice would have handed in second seat with near the utmost, 12.
If you’re in fourth seat with in third seat elevating the opener’s bid, you might be in an “intermediate” scenario. Third seat has 6-9 hcps, principally the intermediate worth of the vary. If opener has 13, that would go away 18-21 for you and your accomplice.
I would not wish to make a takeout double with 9-10 hcps in such a scenario, however do I want 13-14, assuming I’ve good distribution? Or is an “intermediate” 11-12 ample on this “intermediate” scenario? Larry Cohen refers to those as “OBAR BIDS.” (Opponents bid and lift, steadiness in direct seat.)
