Scenario: 9-hand SNG midway, with most players quite regular (no fishes, no professionals).
I raise 66 UTG+2 and get called by HJ. i CBet flop and continue turn for 2/3 pot each street, HJ calls both.
Board is Qh Ts 6h Qc 9h
I put HJ on Q by the turn, since he's unlikely to continue with draws on a paired board. I check the turn, HJ bets 2/3 pot, leaving about 1/2 pot behind. I contemplate jamming but nit-call. My rationale was, with all the draws hitting, a lone Q trips would not be calling a jam, since i can have any straight or flush or full-house. By jamming, i am likely only called by a better hand (QT, Q9, TT).
Assuming my thought process is true (which i know may not be), some players at the table did say that i should be jamming 66 there, since i would put Qx in a tough spot. The question is, is there value in putting people in tough spots even if its -EV (i.e. worse hands fold, better hands call)?
There was a similar scenario in a high roller event where (i think) Pratyush calls an open in position with 66s, checks back the flop, and fires the turn on a A T 7 3 2 rainbow board. He fires the river and gets called by a T, which is what he puts his opponent on. His rationale was that he didn't want a T to have an easy decision on the river, even though its almost always a call.
(apologies, the details on the hands are scarce because they are examples, as the focus on the question is on putting opponents in tough spots)
