Size and position of array

Question

The following is an extract from my LaTeX file which describes a table. The table has a fair amount of space below it. I would, therefore, like to increase the arraystretch. However, by increasing it slightly, the table moves to the next page.

Why does LaTeX think the table is too big for the first page? How can I force it to put the table right after the text?

Thanks!

\section{Payoff Matrix}
\label{sec:Payoff Matrix}

From the brief description in section~\ref{sec:Model and Assumptions} and the full description of section~\ref{sec:Extensive Form}, it is straight forward to create the payoff matrix, which shows the expected payoff to the sender and to the receiver as a function of their strategies.
