| 1 | Pard | You | Hopefully everybody reading this will agree this is a Gerber sequence. |
| 1NT | 4♣ |
| 2 | Pard | You | This is not Gerber. It is probably a Splinter Bid but it may be a weak jump shift. |
| 1♥ | 4♣ |
| 3 | Pard | You | Not Gerber for most. It may be a jump-shift (?) or may be a Splinter bid showing a singleton ♣. |
| 2♥ | 4♣ |
| 4 | Pard | You | This should be Gerber for everybody. I think. |
| 2NT | 4♣ |
| 5 | Pard | You | It depends on what an opening 3NT means. If it is 25-27 points then this should be Stayman. But I'll bet some call it Gerber. |
| 3NT | 4♣ |
| 6 | Pard | You | Assuming the 2NT bid is 13-15 balanced then 4♣ should be Gerber. |

| 2NT | 4♣ |
| 7 | Pard | You | If you play Jacoby 2NT convention then 4♣ here shows a 5-card ♣ suit. Otherwise it would be Gerber. |
| 1♥ | |||
| 2NT | 4♣ |
| 8 | Pard | You | I think this is Gerber, but perhaps some would play it as a new suit?? |
| 2♣ | 2♠ | ||
| 2NT | 4♣ |
| 9 | Pard | You | I can't believe this would be Gerber. I think it is a game-invitational hand with 4♠ and 5♣s. |
| 1NT | 2♣ | ||
| 2♥ | 4♣ |
| 10 | Pard | You | This is definitely not Gerber. It is a control-showing bid, indicating either the ♣A or a void in ♣s. |
| 1♠ | |||
| 3♠ | 4♣ |
| 11 | Pard | You | This is not Gerber in our book. but I don't know what it is, unless it is a Splinter. |
| 1NT | 2♦ | ||
| 2♥ | 4♣ |
| 12 | Pard | You | This is not Gerber in our book. but I don't know what it is, unless it is a Splinter. |
