Today I encounterred a strange Gib hand.
Is such a raise bid normal?
hi lycier,
An expert/advanced is perhaps always bidding 4
♠ (pre-emptive) as West, even vulnerable, irrespective of X or an overcall by the opponents, working on the Law of Total Tricks, and recognising that 6-5-1-1 hands are extremely powerful.
More cautious players perhaps will raise to 2
♠, fearing the vulnerability and encouraging partner too much. It's an interesting hand inasmuch that it illustrates GIB's bids are not set in stone.
A raise bid isn't technically right, but it doesn't make it abnormal as quite a few players will bid that way.
