UGH.

a case can be made for folding third, but you say this guy is not a good player and he is very shortstacked, so I think a call is ok.

However, there is no way you can fold this hand on the river. If you think you are beat on the river, you are probably beat on 6th already and you have a dead out in his hand. His most likely holding is split jacks and you will win, possibly a straight or KK or AA in the hole, maybe trip tens (not likely with the 10 in your hand). I think the range is so large that it is a big error not to call down here. If you are going to call 6th with a Q dead, you shouldn't be looking at it as fill or fold, you have to do it with the intention of calling the river.
