Obviously not going to bid 4♠. The only reason I want to consider double is the auction, how could opener think he is making if he bid only 2♥ the second time? Obviously he thinks he is saving so on that basis I almost want to double. But honestly I think he is going to get a better dummy than he expected, and he is going to guess the hearts, so I pass and just hope to beat him.
To bid_em_up, I see your point about the auction and as you can see I sort of agree. But I don't think that saying it's matchpoints it's only one board pass won't win the board etc. is a good reason to double. For one thing I don't think 50 and 100 will score that differently anyway. But on top of that I don't understand the mentality that we need a great board every hand. I think of it like a cash game in poker. You don't need to try to win all the money every hand, you just do the best you can each hand with what your situation gives you. If that means accepting a possibly lousy score because the risk of making it worse isn't worthwhile, then fine. Getting 3/12 instead of 0/12 is just as useful as getting 9/12 instead of 6/12 on a board.
Josh, it isn't a poker mentality of having to win every board. I am a firm believer in usually playing for average+ and taking good scores as they come. In this case, I believe we are saddled with a
very poor score if we simply pass.
If I thought 4H was a normal contract, I would agree with you. I don't think 4H is a normal contract, unless LHO is walking the dog. If he is, he got me, but assuming partner is competent and will have his X then 3S call, then like you, I don't think LHO is bidding 4H to make. If 4H is making, your likely result is not 3/12 but 0/12 or 1/12, imo. You
pushed LHO into it (or LHO got lucky in his decision). In any case, you cannot expect it to be a "normal" contract. Doubling costs you nothing. A zero is still a zero, right?
It is this point that is key, imo. There is absolutely nothing to lose, whether 4H is doubled or not when it makes. You already have a zero when it makes, you may as well try to improve when 4H doesn't make, but 3S does.
I think the normal contract will be 3S making. In this case, you will again be winning a minimal amount, if anything, when you simply pass. If 3S is making, 4H -1 or 2 undoubled will win very little. I think 3/12 is a high estimate, but I will concede it for the time being. Doubling 4H at least gives you the chance to beat any other pairs who did not X 4H and only beat it 1, tie the pairs who did double it, and assuming you beat it two, not only will you outscore the pairs who beat 4H two undoubled, but you will also outscore everyone playing 3S.
There is practically nothing to lose by doubling, and a significant amount to be gained and in this case, the rewards of doubling are significant enough to tilt in favor of the double. 3/12 is 25%, but 10/12 (or better) is at least 83.3%. So I am risking 25% for the chance to gain at least 58%. If I am right, I will win more than twice as much as I rate to lose. At worst, I turned a bad score into a zero (so I lost 25%). In the middle, I turned a bad score into an average score (gain 25%) and at best, I turned bad score into a great score (gain 50% or more). In the long run, I expect that a decision to double will win more than it loses.
And I will concede a lot of this also depends on other factors as well. The caliber of opponents, my partner, and how many boards the tourny is will all factor in as well.
Assuming the problem comes from a BBO MP tourny, there is a big difference between one board out of 8 where one zero is 12.5% of your final score and a normal ACBL 24/27 board tourny where one board is only 3.7 to 4.1% of your final score. In a short tourny, you are practically forced to double if your intent is to win. One zero out of 8 boards will kill a good tournament, as it is effectively the equivalent of 3 zeros in a 24/27 board tourny. If this was board 8 of 8, and you had a 65% game in the first 7 boards, and you get a zero on this board, your game is now 56.8%, a significant difference. If it was board 27 of 27 and you had that same 65% game going for the first 26 boards, and get a zero, you still have a 62.5% game. Not as good, but certainly nowhere near as bad.
If I see you, Justin, Mikeh or Fred bidding 4H on this auction, I probably pass. If LHO is some random player, I double.
If my partner happened to be you, or Fred or Justin, I pass. I will expect you to already have doubled 4H whenever you had your bids. Opposite a random BBO player or unknown partner or a partner that I know to be weak, timid, etc., you are practically forced to double to protect your side, imo. As I said, I cannot think of a hand where partner can double and bid 3S, and yet he is unable to beat 4H. Can you? (It is possible, I am sure....but it is also highly improbable). If partner doesn't have his bid, well, thats his problem. (Of course, I rarely have this problem and I doubt you do either.....as it is unlikely either of us play with people we don't know already). If partner "knows" he doesn't have his 3S call and that 4H is making (as he rightfully should from our failure to raise to 4S), he should pull the double, imo.
Overall, I still think the double will win. I do not doubt that it can lose on
this particular hand.
