All In:
A player faced with a current bet who wishes to call but has insufficient remaining stake (folding does not require special rules) may bet the remainder of his stake and declare himself all in. He may now hold onto his cards for the remainder of the deal as if he had called every bet, but may not win any more money from any player above the amount of his bet. In no-limit games, a player may also go all in, that is, betting his entire stack at any point during a betting round.
Please use parking coords. You will have a short bushwack to this one. Be mindful that the tree line has an old fence running through it. Watch your step. The hint is in the name.
