RIPETOMATO

My impression so far is a bid of 2C by partner shows a good support and one defensive trick,a 2S is preemptive with likely short hearts but no defensive trick ,3C bid shows good support and two outside defensive trick a 3S shows a preemptive hand, as does 4S bid ,to take away a leeway from opponents.I am open tu better suggestions.Since I play LTC I would reply to the three hands posed by Mr.Ace,2S,4S and 2S respectively and will not bother about the results. I don't have the slightest idea how a passed hand can make a jump cue bid when partner has only over called at one level.I am open to enlightenment.

First of all,I would like to know if you play LTC or not.Playing LTC it means if your over call is on 8 losers bid 3S and if it is on 7 losers then bid 4 S.Since You have 7 losers bid 4S.Same after RHO doubles 3C bid.Believe in your partners 3 C bid which shows 7 losers and a singleton club since you have 3 of them and opponents have 9 .Just ignore the double.If you don't play LTC then too bad.But even then in a regular partnership you must have discussed what the 3 C bid means. Bid according to your partnership understanding.
