Played my first live tournament for some time yesterday, thought this was an interesting earlyish spot:

£125 freeze out

6-handed - table is very passive and rec-heavy.
Hero UTG/LJ A J 12,000
Villain BB 14,000 - definitely a rec, but he joined the table late and had only played 1 or 2 orbits.

Blinds 200/400/400 level 4

Hero opens 1k
Bb calls

Flop (2,600) K Q 4

Bb check
Hero bets 1,200
Villain calls 1,200

Turn (5,000) 9

Villain checks
Hero bets 2,600
Villain tank calls

[I]On reflection I'm not in love with this turn bet. JT gets there. KJ/KT definitely continues; QJ/QT definitely continues; T9 possibly continues and maybe 98 sometimes - but, V took his time before calling flop, so I put him on some middling strength hand and fired again, with the intention of jamming most rivers./I]

River (10,200) 5

Villain checks
Hero - Aborted mission and checked back. After his tanking on the turn I put him on either a super weak K or Qx. But the 9 could have made him 2 pair I guess; the 5 on the river didn't change anything, so I think a rec player might get married to top pair, shrug and call it off; we block QJ so his one pair Qx look like QT maybe Q8-6s; and he could have turned the nuts and he was tanking because he was considering raising.

Having the J blocks hands like JT/KJ - with which I think he'd call - but I also block QJ/J9 which I am targeting.

We just never win by checking back, maybe there was some sizing besides jamming we could use on the river.

I guess ultimately I felt that I had an edge over the table and didn't need to take the risk - interested to get your opinions on this one
