This bidding problem was sent it by Mr. Vassilis Virvidakis Greece U26 NPC.

	No one would redouble today as North. 1 is the standard action, so the problem is not a legitimate one . If we had bid 1

			Double: “It would never have occurred to me to redouble.” 1 is so obviously superior and should be a one-round force. Anyone who plays 1

From this impossible position I double and, asuming that ends the auction, lead my diamond.

	I think the hand in itself is a very good example of why you shouldn’t redouble with very unbalanced hands.
The likelihood that you want to penalise the opponents is very small as they probably have a pretty good spade fit. On top of that, you are left in the blind as to what your own fit with partner is and partner has no idea of suspecting that you have a six card major.
		Even if you play double as penalty on a low level after a redouble like this one, I think double should be take out when the opponents voluntarily bid very high. My plan is to remove 5 to 5
to 5 .

		First of all, I would have bid 1 the first time, making it a lot easier the next time.

It might also be relevant to know what options East had on the 2-level and their style of preemptive openings.
		However, West chose, opposite a passed-hand partner, to double followed by 4 , instead of bidding 4

		The bid that comes to mind in DBL. RHO’s gamble seems to have run into a spectacular defensive holding of ours.
						The main shortcoming is that our hand is rather poor offensively: if partner pulls to 5 , we are in bad shape (ex: Axx Qx KQxxxxx K).
, we are in bad shape (ex: Axx Qx KQxxxxx K).
					
						We ought to guess partner’s shape: RHO’s urgency looks indicative of heart shortness, leaving partner with semi-balanced (or, if systematically possible, balanced) holding. Therefore, the scenario we feared, of partner pulling to 5 , seems unlikely.

Conclusion: DBL.
