you cld write a bit of deal code and test the outcomes I guess.

I played 4 garbage weak2's at MP's for a few sessions and was amazed how much people suicided against it.

assuming you want to bid 2♦ weak 2M only multi as often as possible what is the most aggressive and wide ranging you think you can play? 2 ♥ and 2♠ openers are not available as good weak 2M, most 11HCP hands are opening bids at 1 level. For example 0-10 any 5 card suit at favorable 1st and 3rd. 7-10 1+ top honors 6 card suit at unfavorable 2nd. Is about what I am expecting. How do you play 2nt over this? Do you need to ask how many cards in the suit or do you assume the worst according to the vul? Do you have a bid for a really bad hand at favorable e.g. 3♣? Anyone with answers please post them.

jack can play the hands. If there is a two way guess he will take the most likely guess. That removes most of the perceived problems from the dbl dummy analysis. it is more of a problem in defense where Jacks biggest weakness is probably not always giving declarer a guess in some positions where it can. it doesn't use pure monte carlo. for example if there was ever a two way guess that you can always get right double dummy using pure monte carlo it wld I think never take the guess knowing it can always get it right next trick. You can see this in some primitive programs that cash aces to delay the guess they know is "working". jack has some in built methods for avoiding this.

go here for all analysis. First stop whenever you want to know anything. http://rpbridge.net/

For all of these it is trivial for the person connecting they just have to type in the numbers you tell them to, and if their firewall complains click whatever the box is for yes allow this. Once you have your end set up to allow a connection it is easy. wbridge actions connection type in ip address and port number and what seat you want to sit in for example.

If they both buy a copy of Jack they can play against each other and set the opponents CC to anything they will want for a while at least. Jack will play most conventions. My biggest problem is dbls but I think that will be ok for novices too it does play negative dbls and you can specify up to what level for example provided it is not above 4♠. Qplus will do what you want aswell. Wbridge which is free might be ok. It's ability to play the hands and defend is good enough, the number of options it has may well not be. I suggest downloading the Jack demo and seeing if it is what you want by just trying it offline. Qplus also has a free demo. You may need to understand port forwarding to set up your own connection to each other.

Oh you can buy the original gib if that is still possible from matt Ginsberg and program it yourself and use a script to make it play loads of hands. I did make this work but be warned gib uses an almost incomprehensible method of defining bids.

For dbl dummy ones bbo itself has this which I only discovered a few days ago. http://dealergib1.bridgebase.com/tools/dealer/dealer.php I don't have any programming skill and it is easy enough to use. If you want to analyse hands slightly more realistically I would get hold of Jack. Jack won't play absolutely any system but unless you are trying to do forcing pass or your own version of moscito or strong club it probably has everything you might want except 2 way check back. You can then deal whatever hand shape or auction you like and generate the hands and Jack will either par score them which is just the same as dbl dummy pretty much or you can get jack to play them which he will do with the CC you specify. You can get him to play each hand with several CC's but only at random. Also comparing two CC's is actually hard in that I can't get it to play things twice and then score up automatically. Also in case you want to play the hands your self he can play all the hands and make a tournament out of them which you can play and the boards are scored automatically. Although not perfect this is the best way I can find other people may have found other ways. Qplus will run up to 1000 hand sims for itself and tell you the imp or match point difference between a number of options. Again it has pretty much every convention u might want unless you are inventing your own. It has slightly more strong club options. It has no moscito or forcing pass options. There is a free demo where you can see this feature. Jack and Qplus will also play bridge against you and be good enough unless you are close to international standard that the game won't be a waste of time. You need less programming skill with those than the bbo website but they are less flexible. I don't know of any free bots that will be any use. Also no idea what you can do with gib from BBO itself if you spend money to aquire it. But gib is probably too bad to be useful anyway.

I think it depends if you think your hand is a game force or not, and if 1♦ 2♣ 2♦ 2♠ is a game force or not. If you have a game force it seems responding 2♣ is fine. If you don't have a gf and the auction above is a game force you have to bid 1♠ or you lose the spades.

6c was better than 6nt exactly once in the 100 dbl dummy sim.

and so first time I tried this but I think it was correct. Frequency : 0 0 1 0 2 0 3 0 4 0 5 0 6 2 7 1 8 1 9 0 10 3 11 14 12 56 13 23 Generated 4997 hands Produced 100 hands Initial random seed 1552573274 Time needed 0.917 sec

I got to 71/100 dbl dummy makes 6nt or 7nt. I might try to use the BBO deal program instead though which is better for the dbl dummy questions. I aim to make 1NT 15-17 4333 5332 4432 any.

how about we transfer to clubs and bid 3!♠ assuming that shows a singleton. I can try to do the sim of 6NT.

1NT for me.

Just to point out mine are pretty similar too 30/100 plus 31/100 = 61/100.

Amusingly when I told this to partner he said oh you better alert my 1nt openers too I sometimes have a singleton minor :-). So that kind of removed the problem anyway.

OK thanks

The first screen tells you I.E. won't work it says modern browser and gives a list of examples. Other tables works for me in edge too.

Interesting no one has considered 2♦ which by a passed hand I wouldn't have thought needed many values and just a decent diamond suit and would be readily passable?

[hv=pc=n&n=sjhj9dqjt976ct743&d=n&v=b&b=13&a=pp1sp]133|200[/hv] Playing gazzilli do you respond to 1♠ with this hand ? Does it matter if you are not a passed hand ?

thanks. Ok so playing the same system as someone means making the same bids they do with the same hands ? I am not allowed to think I want to open this hand with a singleton which I know my partner won't ? It seems worse to agree we can have a singleton but not tell the opponents partner can't have one, Or to play we can't have a singleton but occasionally bid 1NT with one.

Just discovered I may be breaking the rules. Note I am in the UK. I am playing a 14-16NT. If I sometimes open these with a singleton I just discovered they are alertable. Now if my partner who never opens these with a singleton bids 1NT is that alertable and what do I write on the CC.

As far as I know other than changing your CC the only robot that you can input what your bid means against is QPLUS. You can if playing with a human press non normal bid or some such button and then describe in as much detail as you like what your bid means. The robot sort of uses this information. For example if you tell it 1♦= 4 + hearts and nothing about diamonds it will use heart bids as cue raises in that auction. There was a move at one point in the World Computer Bridge Championship to have alertable bids explained to other competitors and the interface they use to play the games has or had this incorporated, but I think it has never really been used. The systems allowed are very restrictive and cc's are detailed enough for the most part for them to play each other.

Yes sorry I saw the export and the save as option and made an assumption. You are correct you still can't save stuff to your hard drive from history or a watched vugraph. You can download from the vugraph archive and make a lin. I am downloading the Bermuda bowl for example converting it to PBN and loading it into another program so I can play the hands and compare the results.
