This nasty hand came up with my friend and her partner:



She went two off, although Deep Finesse says it should make. The best contract is a heart game, which would probably be fouind if West had opened 3. The only way I can see to a heart game is if North passes, and South makes an aggressive double in the pass-out seat. North might then bid 4 based on black suit shortages in both hands. No-one else in the room found a heart contract, most were defending 3, either making or one down. Do you think if North passes instead of doubling, South is good enough for a takeout double?

4 is pretty much cold on a cross ruff, essentially cash the A and ruff 3 clubs in dummy and 2 spades in hand, you have 8 tricks and QJ10 left. If W ruffs high you can discard one of your losers.

The rule here is to act aggressively when short in opener's suit, so the double from S would be pretty routine after N passes (as he should), what are you going to do as N if S bids 4 ?

Thanks, yes I agree with being more aggressive in the passout seat in general, especially with a shortage in opps suit, to cater for partner having a stack with no good bid. Care is required at the three level though, because the partner of the pre-emptor could hold a stack themselves, and forcing partner to the four level could result in a significant multiple of -100 on the card. That is the risk you take by being aggressive, but passing is also not risk free.

Did you intend the double as penalties or take-out? It isn't just that you should be more aggressive in the pass-out seat - there is also a good principle that the player with shortage in the suit pre-empted should act if at all possible. So here, North has four spades and no reason to speak. South has a singleton spade and should strain to find the double.

Comment 1: North's double is unthinkably bad

Comment 2: A balancing double by South is reasonable.

I wasn't playing. The North player is an intermediate who I don't think is very good (worse than me). The South player is a friend who is an enthusiastic novice aspiring to improve, and I am trying to help her do that. One of these ways of helping is to look at her bad results when she plays with this woman once a month, and advise if they could have done better. In the most recent evening, they finished with a respectable score (a shade over 55%), and most of their poor results were not their fault (e.g. the cold game against them bid by only one other pair). I do partner her once a month on one of the stronger evenings as well.

Thanks, that is along my line of thinking, and is pretty much what I told her. I thought I'd post it here just to be certain I haven't missed anything.

In’addition to what other posters expressed about balancing, you can also give your friend more advice about responding to a TOX.

Indeed, she could have bid 4D with sth like

xxx
Qxx
Jxxx
xxx

Facing a normal direct TOX (short S and a very sound opening hand, or a powerhouse of its own), with an opening hand herself, a singleton and a secondary support for partner’s implied H, she should not content herself’ with 4 D but should commit to game.

Actually if I had just 1 bid, I’d rather chose 6D than 4. Unless I know partner Xes with such hands where any answer is then pure random.

With a 54 in the minors, it is probably better to bid 4NT (pick a minor) and play in a 44 C rather than 53 D fit. If this is too advanced bidding for her, she should just blast 5D.

Overall, you have a good educational hand on what is a TOX, what principles guide you for balancing, and what to to when partner Xes for TO.

FYP

All these great intermediates working together with honours make the South hand really good.

Sir,
1) The TOD by North is just HORRIBLE.
2))If N passes then Souith hand is all too thin to make aTOD at this high a level
3)The 4D contract is all to easy too make on a cross-ruff.
4)After a TOD by North I would have preferred to play in the Moysian 4/3 Fit in 4H.The number of too many losers in D and C makes 4H more appealing to me.(Our TOD by N guarantees at least four two high honored cards in hearts AND no wasted values/length in the spade suit bid by West,).

Possible but risky would be to call 3NT not double.
I today;s climate some thought to playing penalty doubles in some cases.
Pass stands out here since the auction is not over and partner will double with most reasonable hands.

For once we more or less agree :)

This rule is insane. Bidding anything other than double with x KJx AKxx AJxxx would be horrible. What are you going to do - 4C?? 4N?? PASS???

If we don't have any Spade honors and RHO can't raise...
