glen Posted May 10, 2015 Report Share Posted May 10, 2015 One of the more interesting systems ever played in the US will be in the US Open knockouts today. Dinkin-Tunçok call if "Modified Fantunes" but it really is unique. Here is the 1-2 second opening structure that they used in the Round Robin to get into the KOs today: 1♣: 10-14 all purpose, either:- 13-14 balanced, can have 5cM- 10-14 unbalanced with a minor - 10-14 three suited- 10-14 5-4+/4-5+ majors- 10-14 7M (7321) 1♦: artificial, 15+, no 5cM except in 1-2 can be 5440/5332/5422 1♥: 8-10, 4+♥s, may have longer second suit 1♠: 8-10, 4+♠s, may have longer minor 1NT: 10-12 2♣: 15+, 5+♥s 2♦: 15+, 5+♠s 2♥: 10-14, 5+♥s, fewer than 4♠s 2♠: 10-14, 5+♠s, fewer than 4♥s 2NT: 20-21 balanced Now that they are in the KOs the system mutates so all two bids are closer to Fantunes. Here is the 1-2 seat structure: 1♣: 8-13, either 8-10 all shapes, or 11-13 and:- three suited- 5-5+ any two suits- 5-4+/4-5+ majors- 7 card suits 1♦: artificial, 14+, 14-21 no 5 card card or longer major or 22+ any 1♥: 14-21, 4+♥s (5+♥s if minimum), may have longer second suit 1♠: 14-21, 5+♠s, may have longer minor 1NT: 11-13, includes all 5332s/5422s even if both majors 2♣: 10+ to 14-, 5+♣s 2♦: 10+ to 14-, 5+♦s 2♥: 10+ to 14-, 5+♥s, fewer than 4♠s 2♠: 10+ to 14-, 5+♠s, fewer than 4♥s 2NT: 19-20 balanced They will be using their big diamond system today and tomorrow to try to upset the #1 Diamond team 2 Quote Link to comment Share on other sites More sharing options...
Free Posted May 10, 2015 Report Share Posted May 10, 2015 Interesting system, but if this is modified Fantunes, they have no clue what (unmodified) Fantunes is. Quote Link to comment Share on other sites More sharing options...
Trinidad Posted May 10, 2015 Report Share Posted May 10, 2015 To me this looks more like Magic Diamond than Fantunes. (And I like Magic better than this "Modified Fantunes" system.) Rik 1 Quote Link to comment Share on other sites More sharing options...
gwnn Posted May 10, 2015 Report Share Posted May 10, 2015 1♠-?only 1NT non GF (yes, even 2♠ is GF, with diamonds perhaps)! 1♠-1NT2♣=0-2 hearts2♦=3 hearts2♥=4 hearts pretty refreshing to see something else in action. Quote Link to comment Share on other sites More sharing options...
PhantomSac Posted May 10, 2015 Report Share Posted May 10, 2015 It is definitely interesting to play against. Quote Link to comment Share on other sites More sharing options...

straube Posted May 11, 2015 Report Share Posted May 11, 2015 I'd be curious to know their 1C response structure. If 1C-1M is nf and 1C-1D is GF then how do they handle the GI hands? To compare or contrast it with the Recursive Diamond (a strong diamond system), the 1C here has far more hand types and a wider range while the Recursive Diamond's 1D response to 1C is GI+.

Kungsgeten Posted May 12, 2015 Report Share Posted May 12, 2015 When I played forcing pass our 1C opening was like Magic Diamond's (similar to the system described but stronger). 1C was any 12-16 unbalanced or 15-17 NT. We used the 1D response as two-way: a weak hand (0-7 in our case) or any GF (12+ for us). The other responses showed Constructive values (about 8-11). I think a similar structure would work over their 1C, with adjusted point ranges. Quote Link to comment Share on other sites More sharing options...
benlessard Posted May 12, 2015 Report Share Posted May 12, 2015 If 1C-1M is nf and 1C-1D is GF then how do they handle the GI hands? Opener wont pass if hes max. so responder will have a 2nd shot. Quote Link to comment Share on other sites More sharing options...
