Grasping for gains he already grips,
Striving for stakes he has won,
Dad hones his steel shank on his own son’s small slips.
Grasping for gains? He already grips
A fear of benign — yet he holds all the chips.
Will he ever soften what he thinks is such fun,
Grasping for gains he already grips,
Striving for stakes he has won?

What is a triolet?
The rhyme scheme of a triolet is ABaAabAB (capital letters represent lines repeated verbatim).
