Answer

Creo que el significado que andas buscando es el siguiente:

1.¡Hasta Richard es mejor que yo!  
2. ¡Hasta Richard es más inteligente que yo!

Esto expresa que yo soy pésimo haciendo algo, en lo cual hasta alguien como Richard puede hacerlo y yo no. En estos casos puedes usar la palabra "hasta" para expresar tu "even" en el principio de una oración.

Espero encuentres esta información útil.

Answer

Also, the word "aún" can be equivalent to the English "even".  Much like the word "incluso".

Aún más.  Más aún.  Even more.
Si lo hacemos pronto, nos divertiremos aún mejor.  If we do it now, we'll enjoy it even better.

In the case of siquiera it can mean even if. 
Does siquiera only mean Even If at the beginning of a sentence? If it's not the first word in a sentence does it mean  at least or even?

Answer

"Even" in Spanish, means "Incluso" Example:

Todos pueden bailar incluso yo (Everyone can dance even I).

But watch out because also could mean "Ni siquiera" like your example:
It's not even possible. (Ni siquiera es posible)
