I've got 10k, sitting at a 50/100 table with fizzlesticks and a bunch of unknowns. I get dealt KA spades UTG. I pop it up to 350, guy on my left with a full stack calls as well as BB (he had about 5k I believe). Flop comes [10s Qs 4d]. I bet 600, about half the pot, looking to get raised. Guy on my left calls, BB folds. Turn comes 8d. I bet 1500, he calls. River comes 3s. I bet 3k. Guy folds. Thoughts?
