This is a good hand for partnerships to discuss. It is more a matter style than right or wrong. I do not want my partner to jump to six spades with the hand he holds--so I would close my eyes and bid 2 spades---If you believe that opener can bid again with his hand after 4 spades then 4 is fine. I also want partner to splinter over my 2 spade bid---.

I would probably bid 1 heart at match points and 2c at imps--I agree with most of the comments---I see no reason to overcall with the opponents hand 2D only helps the opponents

Making a positive response over a 2 club open should show more than a ragged 5 card suit. It surprises me that so many responders want to take control of this hand. Bid 2 diamonds and wait.

I would probably pass in 3rd seat and 4th.

In Japan you are allowed to open 1nt with a singleton A or K or Q--otherwise it is forbidden

I am reasonably sure pairs like that do not win events---6 spades is absolutely nuts---

Of course your RHO opponent should have used the stop card--to give you time to think. In general I leave such auctions alone--Yes 4 spades could work--but it may not. ]

Partner should know that a 3 diamond bid endplays me--I think 4 clubs is automatic--if partner rebids 4 spades I will pass---I would jump to 5 clubs with 5413 distribution.

It means whatever you choose to do...it is your fault. These kinds of bids end partnerships.

One comment regarding imps---it is not frequency that determines what you should bid--but expected value--matchpoints is a game of frequency. At imps vul if you are bidding game is 40/60 you should bid it.

The problem with a reverse is you cannot stop at 3 diamonds---there is no trouble converting heart to spades. If you rebid 3 diamonds over 2nt(NF) then I think 2 hearts is clear. If you do not have that agreement you make your best guess. I would be aggressive at imps but that is just me.

If you believe your contract is normal then you should take the percentage line. That is the easy short answer---and if you believe the field will be split---you should still take the percentage line for the most tricks. You only adjust your line when you are in a brilliant contract--that only needs to make or you are in a contract that needs everyone else to be wrong.

Why would I want to push my opponents into a 7 spade contract that makes. Bidding 5 clubs helps the opponents does not hurt them.

If you believe this auction is forcing then South must double--I strongly believe that a 2 diamond response should not be game forcing in this auction--but if your agreement is that it is game forcing then South must double as a pass indicates bidding more is ok. Otherwise in a non forcing auction North must double.

I strongly disagree that 2 diamonds creates a forcing auction. Having said that, I double with that hand--If 4 hearts is making we are already booked for a bad score and if I don't double we cannot protect our plus score.

I would always open-At pairs not opening when you have spades is dangerous.

Assuming that the doubler knows what he is doing --of course it can be profitable--but it is a matter of frequency--there are far more hands where using a double for another purpose would yield positive results.

I believe this is a hand that partners should talk about. For me a 3 spade jump is quite strong(only pass if you opened a real dog) so in that context I believe partner should cue bid.

If 2nt is natural and invitational--then bid 3nt or pass as you like. If 2nt is a scramble then bid 3 heats--partner should have 5 good hearts or 6 hearts and 3 diamonds. Without discussion I would take 2nt as natural and pass--bidding 3 clubs is very bad. If partner has clubs no trump will play well.

If the bidding is to be believed partner has nothing--while leading a diamond may give away a trick--you will get it back by continuing them at every opportunity--you really don't care which hand ruffs-the problem with safe leads is that the trumps may be solid enough for the declarer to lead them at every opportunity.

I pass--I do not like two spades because partner knows I do not have 4 spades--unless I am very weak--no negative double-- and if partner is strong and has 4 spades 2 diamonds doubled may be the best spot-- Frankly the auction could have been 1h-3d.... now passing is even more frightening--I can live with -180.

If you say it a good standard--that is you can depend on your opponents to bid reasonably---I think it is reasonable--partner is marked with spade length and a not so good suit--so a smattering of points. I wouldn't find it at the table but other leads are just as dangerous if not more so.

Given the constraints on the system--you have end played partner into 3nt--you should bid 4 spades over 3nt--you are too strong to pass let partner describe his hand
