Bread N' Butter Part V


This is Part V of the Bread N' Butter series: a look at Meckwell bidding in the last world championship when one of them had 10 to 17 balanced, either in opening position, or directly over an opponent's opening. We will consider balanced as any 4-3-3-3/4-4-3-2/5-3-3-2, plus any hand that Meckwell treated as balanced.

Part IV of this series was posted on September 21st, and since then we've looked at some theoretical concepts that can be examined as part of this series. For this and upcoming posts in this series, the postings will consider two potential modifications to the Meckwell style 1D opening:

1) Removing the unbalanced diamond hand types, and thus a 1D is a single hand type: 10/11-13 balanced or semi-balanced.
2) Adding 5-3-3-2s with a five card major, 11-13, into 1D, treating these as a balanced hand opening, and not a major suit opening.

With the news this past weekend that the Netherlands will host the 2011 World Championship (likely late October 2011, exact location not established yet), we will resume the series with the second match on Day 4 of the round robin against the dangerous Netherlands team.

On board 4, Rodwell opened a flat 12 count, and next made a support double. After the three club fit bid (spades + clubs + values), note that Meckstroth's three heart bid is to play, and does not invite in any way. Bakkeren got to a decent game contract and Rodwell led the diamond ace, and then switched to a heart. After drawing trumps, declarer knocked out the diamond king, and then later took a ruffing finesse in diamonds, leading the diamond ten and hoping Rodwell had the jack. Instead Meckstroth had it and that was down one and 7 IMPs to USA2.

On the next board Rodwell opened a flat 11 count in fourth seat, even though he was opposite a passed partner who would have opened any 11 count. However the 4-4 in the majors were nice, and opening 1D got them to 1H making 1 for a push.

On board 8, Meckstroth opened the balanced 17 with 1C since 1NT for them in 3rd seat is only 15-17 when vulnerable. They landed in 3NT for a push, Rodwell's 1NT showing a game force with a spade stopper.

On board 10, Meckstroth opened a flat one heart, and Meckwell had nothing more to say. If 1D would be the system opening (if 5-3-3-2s with a 5 card major are treated as balanced), the contract would likely be the same. In the other room, Zia as South overcalled one spade (their jump overcalls vulnerable are Intermediate), and this allowed East West to reach 3D making. 2S against Meckwell was down one for a push.

Board 11 had a balanced hand but due to a power outage just at the time there is no record of the bidding. Here is the hand from the other table, where they got to a five heart contract:

This was an amazing hand, as Meckwell got to 6H, played by Rodwell, West. On a neutral lead, Rodwell drew trumps and stripped out the black suits, then led a diamond to the king. To beat this North just needs to duck this, and wait with his AJ of diamonds over the queen. Instead he took the king and returned a diamond. Now Rodwell had to guess whether North made a mistake or not. He assumed he didn't, and played the eight from dummy, covered by the nine, and down one losing 11 IMPs.

On board 15, in the other room Hamman, North, opened 1NT with a singleton king and played there, making. Against Meckwell, North opened one diamond, and Meckstroth overcalled one spade. Rodwell showed a spade fit and something in hearts (not much something here) a mixed raise (constructive values with four or longer trumps - thanks to David Morgan for this correction) with a three bid, and Meckstroth parked it in the part score, just making for 6 IMPs. With a game swing on the last board, USA2 had won 40-30, 17-13 in victory points.

    Re Bd 15: I think you will find that 3H is not a fit-showing jump but a mixed raise. They appear to reserve 3M-1 for such hands, with 3M preemptive.

    On board 10, I think I would be likely to compete over 2S opposite a 'guaranteed balanced' 1D opening, since we have at worst a fair 5-2 diamond fit, and quite possibly a better one.

    David - thanks for the correction!

    Roy - I would compete as well (or as Meckwell) but I wasn't sure that would be a mainstream view
