I think a value bet on the river isnt the right play at all, because which worst hand will call you? maybe qj and some pocketpairs and to turn your aj in a bluff is a even worse idea. to let the opponent bluff is the best play. so you play it quite well, even if i think it isnt a snap call at all. You have to think with which hands he would overbet the river.
obv. with every 6 but there probably only the a6 maybe the k6s , then also the kk,jj and 88 but that would be an interesting line to take with this hands. he might have kt or kq here and play it tricky because there isnt a big chance for you to have a big hand on the river its quite obv. that you have an jack there,so he might think a big bet would be a good valuebet with kq,kt ,which it is. on the other hand would he check it on the turn. probably yes.
what hands he can bluff the river . i would say all ace high have enough check equity and pocketpairs have enough equity for sure and nl10 player wouldnt turn these into a bluff i guess, so there arent that many hand left he can bluff with . at the end it not a bad call and its an important note to see if he bluffoverbets or not ,because it not so often in smallstakes that players balance there overbets at all.
at the end i would probably play the hand the same way u did.

One thing that coul be a reason for you feeling that you beat the 5/10 easier is,that first you cant concentrate if there is to less money on the line ,bacause not only fear money make u a worse player but also playing with money which means nothing at all to you can make you a worse play than you would be on the perfect Stakes for you and second you might have Problem to adjust to bad players but you are good enough to beat the 5 dollar games(which are soft as well) . To adjust to fishes is a important point to work on then ,because if you play higher its important to spot the Fishes at your table because a lot of money coming from them!!!

I made one mistake in the second example. I wrote " i would prefer the 4 bet shove here" . i meant the 5 bet shove because the opponent 4 bet in this example .

This kind of problem often occured to me as well and a friend of mine helped me with some mathimatical examples. Let assume for both examples 100bb and its 6max.
1.Let say you are in the Co and raise 3 bb with QQ . You get 3bet from the bu to 9bb . you 4 bet to 27 bb and he pushes allin for his 100 bb. you have to call 73 bb to win 200 bb. you need 37%(with rake and to have more than a marginal ev+ a little more) to make this call profitable. Now is the question how much equity we have vs the range of villian. Vs a qq+,ak range we have about 40% and a call would be slightly profitable. Vs a jj+,ak+ hand we already have 48% (would be 23bb per call(massive). but on the other hand if he is very tight or like to flat strong hands and never 5 betbluff( like nobody does that on smallstakes and is a good player i guess) he might have a kk+ range with give us only a 19 % chance of winning the hand. vs a unknown player in smallstacks i would probably call here very often ,because there are enough fishes who maybe even 5 bet shove with tt or sth aq or who are on tilt or who are maniacs and the rocks that only go broke with aa,kk are not as much as the other types i would say.
another alternative is to only call the 3 bet. But if u have some bluffs in your 4 bet range i think to 4 bet with queens are very fine and to play oop with ur queens when u only flat isnt so nice to play .(you often loose even to smaller pairs like jj if an ace or k is on the flop cause you have to play check/fold., if u 4 bet they may call and on the flop u can play bet/fold or they 5 bet all in or they even fold which is the downside of the 4 bet of course.
2. If the Co open for 3 bb you 3 bet to 9bb on the button and he 4 bet to 27 bb i think its more difficult. first of all his range is normally a little bit wider than last example when he 5 bet shoves. on the other hand if we 5 bet shove its harder to imagine someone go broke with jacks and even ak is here a fold more often i guess. Another thing is we play our qq in position if we flat the 4 bet and jj and tt and some bluffs could be in his 4 bet range way easier than in his 5 bet shove range,so we keep them in ,but we dont have the initiative so we may lose on a lot of kxx and axx boards .neverthelessi guess i would prefer the 4 bet shove here.
this two examples are quite difficult i am intersted at your opinions.
if u got kk you always have to broke in normal cg preflop . YOU HAVE TO! and if your were the button in the first example and u would get 3 bet from the sb i think a flat is a very good alternative and if u are in the sb and 3 bet the qq and he 4 bets u its a clear shove 5 bet for me . i hope it wasnt to long and help you a little bit ;)
