The silly posts' regarding opponents possible point counts is an indicative factor for bidder to bid a game assuming average ditribution of partner.Nobody should think of himself as sole custodian of great bridge wisdom.Moreover recent joining in bbo forum does'nt mean that he/she started playing bridge from the other day.
Bidding of East is revealing in vulnerable condition with only 3nos of spades.He is short in one suit(probably D) & from bidding expecting west to be short/void in other suit i.e hearts.I will play East with all missing H.
It appears they will be trying to establish a long side suit in norths hand(presumably diamond judging my hand & bidding ) by xruffing to discard loosing clubs. So CA it is.
