Player6 (MP2): t19001 1 BBs – VPIP: 17, PFR: 17, 3B: 11, AF: 5,5, Hands: 109
Player7 (CO): t9810 1 BBs – VPIP: 24, PFR: 3, 3B: 0, AF: 1,5, Hands: 271
Hero (BTN): t41894 1 BBs – VPIP: 24, PFR: 16, 3B: 7, AF: 2,5, Hands: 274392
Player9 (SB): t27096 1 BBs – VPIP: 21, PFR: 18, 3B: 6, AF: 0,0, Hands: 38

Pre Flop: (t0) Hero is BTN with A T
4 folds, Player6 raises to t1672, 1 fold, Hero calls t1672, 2 folds

Flop: (t3344) 5 K Q (2 players)
Player6 bets t1974, Hero raises to t4724, Player6 raises to t17254, Hero folds

Here I did bluff raise, I try to get let V fold, all his Ax hands, maybe weak Q`s and any pair or connectors hands, + if I get called, then I have a backdoor nutflush draw, overcard and a gutter to the nuts.

Obv after his shove I fold.

Does my play make sence here?

Next hand (hand 2)

Here I think, I raise the flop cause the bord is pretty dry and there is not mutch V could hit and I didn`t V would catch something on the turn and/or River by checking back.

Is this the right play or should I think in order of showdownvalue?

Some thoughts/criticisme is welcome, thanks.
