It is said that Clave is the core of Latin dance but I'm totally new to this kind of instrument. (only old mans said?)

Can any one help that with its boom 2 3 in one bar and 5 & 8 in the next bar how can I step Int Rumba (I'm familiar with the counting 2 3 4)? I showed the question in other forum but seem that it is hard to be answered.

It seems that Clave is not necessary for us, the Int Latin dancers in the present time? I see no Int Latin Dancers and Coaches teaching about clave?

Dancelover2012. To my knowledge a clave is not an instrument. Just forget you ever heard the word. Remember the Basic Rumba has 3 steps over 4 beats. Beat one is a hip movement only. That's all you need to know at the beginning. Later you may play around with the rhythm for a different effect using an and count.
