checking the odds
Ken, I am not sure a dummy reversal improves the odds in a significant way (apart from the case where s run but trumps are 4-0, in which case the dummy reversal is indeed better). If s do not run, I think the dummy reversal option becomes infeasible (one needs ...
checking the odds
1) Assuming partner has 4 trumps: If s run (i.e. either partner provides the J or s split 3-3), you need to be facing at most 6 red cards (then, s can be discarded on s and your loser ruffed in dummy); this also needs trumps not 4-0 ...
Delayed spade overcall
4+ s, could not overcall on previous round but wants to compete. E.g. (but not necessarily) a 4-card suit with some length (increases likelihood of decent support opposite while unsuitable for a balancing X). In short, any of the first 4 items in the poll might ...
Should South find a bid with this hand?
Overcall the 1 response with 2
Julien Christen's bidding problem: J763 962 Q84 K95
The "willingness to penalize opponents" interpretation of XX seems problematic in this sequence, or at least requires elaboration (3 fast tricks?), as opener cannot have good opposition in both red suits.
Can you change your mind after doubling to show a big hand?
Since partner could not find a bid over 1, (s)he is not going to balance us into anything now if 2 is passed out, so no need to worry about that. We know that partner does not hold a weak but shapely hand (else we would have ...
Wich line for this 6!c ?
Line 3 (finesse against N) is clearly inferior to line 2 (ruffing finesse against S). Then, line 1 beats line 2 against Qxx(N)/xxx(S) while line 2 beats line 1 against xx(N)/Qxxx(S), the other divisions being irrelevant for comparison (with both lines either winning or ...
Forcing or not?
Spencer, I think your rule works fine in some cases (like your example), less so in others. For instance: 1m - 2SA (INV) / 3m is normally played as showing a minimum 1-suiter unfit for NT play (and hence NF). Some partnerships would also play 3 to be regressive in 1 ...
Forcing or not?
The question as asked seems invalid to me because I do not see a clear deductive argument leading to a yes/no answer (regarding the case of s). In other words, it is a matter of systemic choice rather than logic. FWIW, I happen to play with my main partner ...
ATB-missed game
East was perhaps a tad conservative in not raising 2 (a balancing bid that could be made on a very weak hand with a 6-card suit), but the 7th makes 3 (instead of 2) a standout, so I give most of the blame to West
