shove, unless you have a read that villain will bet into weakness.

but, the draw missed. and under cards hit the turn and river. i doubt you get much here anyway. but, he did call the bets, so keep betting. i just think its unlikely he will bet if you check.

in a deeper stack situation, you dont necessarily want to shove here. you would bet more of a half to full pot bet.

but, since you only have about $1.25 left...and thats barely more than half the pot...you shove it all.
