Slam Bidding.
In my opening article entitled ‘Under new management’, I mentioned my intention of reporting on the NTL matches as well as the county matches. I had not intended to start immediately but the match on 20/3/24 raised a very important issue. Slam bidding is so very important at teams because, if you lose a slam swing, you may not be able to recover from it.
All 3 of our teams were playing this week and Amethyst and Emerald were drawn against each other. Agate managed to lose by 1 imp and the whole match revolved around slam bidding. On boards 7 and 8, our team mates bid a slam on 8 and stayed in game on 7. Unfortunately, they should have bid slam on 7 and stayed in game on 8 but, to be fair, these were not straightforward hands.

South opened with 3© and, from then on, bidding the slam was going to be problematic, but not impossible. West doubled probably so that he can show a big hand on the next round. However, East jumped to 4ª and this left West with a problem because he could easily imagine that North could have a heart singleton and was about to obtain a ruff. Quite understandable really.
At my table, the auction started in the same way but, over the 4ª bid, West bid 4NT (RKCB) and, after a response showing 2 card keys, the slam was bid as if there was no problem. At no time was the heart void shown and so the slam is a bit on the speculative side.
Unfortunately, I think that this had an effect on board 8 because there was a temptation to try to make amends for the previous hand.

Unfortunately, at my table, I decided to overcall the 1ª opening bid with 2©. East cue bid 3© and Ralph jumped to 5©. This was good tactics at least most of the time but, on this occasion, it made it virtually impossible to bid a slam.
At the other table, our team mates had no interference to contend with and sailed into 6ª. This was an impossible contract with the ace and queen of diamonds lying over the king. It is difficult to spot the 5-4 fit when you have already found a 6-5 fit and so it is not too surprising that the diamond losers were overlooked. The auction went like this :-
West North East South
1ª pass 2NT pass
4© pass 4NT pass
5© pass 6ª all pass
2NT was a good spade raise and 4© was a splinter. 4NT is RCKB and that was followed by the slam. I cannot say that I am happy with this auction. There is an horrendous duplication of values in the heart suit. AQ opposite a void is a terrible waste of values and would suggest that there is a ‘hole’ somewhere else. I do not like RCKB after a splinter, cue bids usually work better. I would have bid 5§ over 4©. Then West would have to sign off in 5ª because he has no diamond control. Then East might have felt that 6ª was a step too far.
In the Amethyst/Emerald match, Paddy Lockwood and David Allen did well to bid the slam on board 7, although they had it a little easier than might have been the case, when the opening bid was 2©, rather than 3©. As the South hand only held 4 points, the hand is not technically strong enough to bid 3© especially at the vulnerability and so it would seem to be reasonable to play the hand as a weak 2. However, as is so often the case, the technically accurate bid can be less effective than the ‘tactical’ bid. The 2© opening bid gave David the opportunity to bid 3© to show a strong hand with sufficient bidding space to find a fit. Blackwood looks far more useful from the West hand, but it prevents any chance of bidding the grand slam, but that would be very difficult after any opening bid made by the opponents.
Unfortunately, they were not as successful on board 8 but anyone who bids a slam on this hand should not be too upset. The difficulty with the hand, as described earlier in this article, is the diamond suit and, unless you play a relay system such as Ralph and I play, and unless there is no interference bidding, it is so very difficult to get this one right. In fact, you need to be a good guesser.
Finally, the last slam of the match was board 16. At my table, I was rather surprised when our opponents failed to bid the slam. I put in a 2§ overcall but it was more to secure a decent lead if Ralph became the opening leader than to achieve anything in the auction. It hardly seemed to be a big problem for them to overcome, but neither opponent felt that they were strong enough to make a move towards slam.
At the end of board 15, we had fought back and recovered 12 of a 13 imp half-time deficit. I had high hopes that our team mates would be able to find the slam and win the match for us. But it was not to be. They received far more interference bidding than Ralph and I put up and so they settled for a ‘safe’ game.
But in the Amethyst/Emerald match, Richard Evans and John Bloomfield conducted a fairly simple auction and bid the slam. However, this hand intrigues me a little because the strength of the hand lies in the double fit. If it could be possible to determine that East/West held a solid 9-card spade fit and a solid 8-card diamond fit with aces in both short suits, it would be easy to bid the grand slam. It is possible to get close to it using a system such as the one that I use if there had been no interference. The hand was :-

With no interference, Ralph and I would bid :-
West East
1ª 10-15 pts, 5+ spades 1NT relay
3¨ 5+ spades & 5 diamonds 3© game forcing relay
3NT precisely 5251 dist. 4§ control ask
4ª 5 controls 6ª/7ª?
East knows West’s precise distribution and that he holds 5 controls (ace= 2 controls, king = 1 control), which can only be 2 aces and a king and not 3 kings and an ace because East has a king and singleton kings do not count as a control. Unfortunately, the grand slam depends on which king West holds. If he holds the heart king, the grand is dependent on a finesse whereas, as it is the diamond king, the grand is a lay down. As grand slams should not be bid on a finesse, we would be obliged to settle for the small slam.
However, there is a way that this grand slam can be bid. There is a little known asking bid that would supply the answer. In the sequence above, 4NT over 4ª would ask for queens but a bid of one of West’s short suits immediately over the 4ª bid would ask about the suit bid. Responder is obliged to show if he has anything more in the suit than has already been shown. Therefore, East bids 5© and 5ª would show nothing more than the ace already shown and 5NT would show the king. When West bids 5ª, East knows that West’s king is the king of diamonds.
Unfortunately, an elegant sequence such as this one is impossible when there is any interference and so we would have had to settle for the small slam. Slam bidding is so important at teams because one slam missed could cost you the match particularly when playing only 16 boards. There are so few boards available to make up for it. Bearing in mind that the reason for us joining the National Teams league was to improve our performances, it might be worthwhile looking at your slam bidding methods to see what might be done to improve in this area. I am not expecting anyone to change to my methods, but many slams simply cannot be bid with any accuracy if you rely solely on Blackwood.
To some extent, the same arguments can be applied to games at teams. We cannot afford to miss one because a game swing takes a lot to recover. However, bidding games is so much easier than bidding slams. In fact, it is often good tactics to adopt a bullish philosophy and just jump to game when there is any chance of success at all. The odds change, though, when a slam is a possibility. Whereas, if you punt a game, there is every chance that your opponents at the other table would also bid the game, that is not necessarily the case when considering a slam. It is more important that the slam should make.
Therefore, slams require careful consideration of the pair’s full assets and, if you are not sure, you will often be better off settling for game. Certainly, just bidding Blackwood will often not be enough, particularly when there are singletons and voids about. Blackwood is only there to check that key cards exist and gives no indication of overall strength, and how many of you have the methods required to show queens other than the queen of trumps? This can be vital when considering a slam in no trumps.
Of course, I am not the best person to be giving advice on how to bid slams using a natural system. I only use natural systems when there is no alternative. But I feel that a fairly easy natural sequence would be sufficient on this deal :-
West East
1ª 2NT strong raise to 3ª at least.
4¨ 5-5 in the 2 suits 4NT RKCB
5© 2 key cards 6ª
This does not show the king of diamonds, but West has nothing in spades and must have more than 2 aces for his opening bid so 6ª should be good. Any of you Acol experts who have a better sequence, please let me know. Unfortunately, at every table, North overcalled with 2§ and, at some tables, clubs were bid several times making it very difficult to bid the slam. However, East should bid 3§ (Unassuming Cue bid) or 2NT, if that is your method, to show a strong raise in spades. After that, it will depend on each pairs ow methods. Would 3¨ show a suit or is it showing slam potential and a top diamond control?
Some play that 3¨ shows a diamond control and denies a heart control and so 3© would show a heart and a diamond control and 3ª shows none of these and a minimum bidding 4ª with no outside control and a maximum. This seems to be a useful understanding to have.
Most Precision players use either Italian style asking bids or relays where the strong hand asks specific questions of his partner and partner gives specific responses. There is no need for ‘flair’ or expert ability because the work is done for you by the system itself. In natural systems, the main method for bidding slams is by using cue bids and these are open to interpretation and not everyone interprets them in the same way. Good partnerships need to work on this area together so that they are sure that both members of the partnership use cue bids in the same way so that the correct information is given and understood.
