Early stages of $350 live tournament. Hero has $22k of 25k starting stack. Villain is a competent thinking player Hero has played with before, aggressive but a little splashy. Villain likely perceives Hero as solid and on the tighter side.

9 handed, 50/200/400 blinds. Hero is in SB with Kc5c. Two early/mid position limpers, then Villain (16kish effective) limps in cutoff. Hero completes and BB checks.

Pot: 2450. Flop Ks 5s 2s.

Hero in SB donk-leads 2k. (Thoughts on leading out versus x-r line?) Three folds, then Villain in cutoff makes a small raise to 5050, leaving himself about 11k behind.

Do we jam here, or call and plan to shove non-spade turns?

Given our blockers, Villain's value range is heavy skewed to flushes. I'd expect bottom set to raise larger, and the remaining pair/FD combos (like Kx/QJ10s) to flat call given the strength of Hero's lead. Villain is almost certainly raising a naked As here too, so folding feels way too exploitable, but perhaps I am wrong.

Call.

I think leading out on this flop is almost always correct as letting it check through to a V with any single spade is bad.

I'm not sure I'm jamming a non-spade turn. You could also bet to leverage V's smaller stack.

I like the donk bet in an unraised pot with the monotone flop, as well as the sizing.

If you think V is a good player, his raise is small but he is setting himself up with an optimal size for a bluff/semi-bluff shove on the turn, particularly if he holds the As. Had he bet more, he'd be leveraging his stack poorly because he'd be giving you good pot odds to call the turn. I think this might make me more likely to call the flop and x/c a turn shove.

If he were betting that flop for value, and to play for stacks by the turn, I think he should have bet a bit more on the flop to set up a smaller shove.

I think this simply becomes a question of whether he's already got the flush. If so, you're way behind. If you believe he has the As, it becomes a flip. If you add in the rest of his range, it reduces his odds pretty significantly. I like a shove here, but perhaps a call would be slightly better. If he calls your shove on the flop he's not doing it with anything less than a spade draw. If a spade hits the turn it gives you the opportunity to get away from it, but if no spade, I'm shoving the turn, which he'll probably fold and you'll take it down.
