In 6max tournament decent, slightly loose agressive player raises 2,5x in highjack. I 3bet 2,5x from the button with 9d 9c. Everyone folds, then he decides to call (both 60bb deep).
Flop comes Ks 9s 5s. He checks I decide to bet 55% of the pot and he calls. Turn 8h. He checks I bet 55% again and he calls. River 6c. He checks and I check back. I know I may be losing certain value by not beting because of Ak combos (hard to explain he is not 4beting me preflop tho). I'm more inclined to check because of all the Ax spade suited combos which he could be slowplaying me. I just see very few value combos with which he would call 3barrels (being quite a solid player) and I would still be in front. Do you think I'm losing value by not betting or is my thought of protecting showdown value legit? Let's see what you guys think!!
